AC Nexus Advanced Power Distribution & Ground Enhancement System: $20,000
Steve McCormack, once the proprietor of The Mod Squad, is the man who introduced the concept of accessory isolation feet—his Tiptoes were aluminum cones with flat tops and sharply pointed feet. Now he's brought to market this passive AC-power filter, whose Panzerholz enclosure contains two fist-sized silver-conductor capacitors from Duelund. The IEC AC inlet is a Bocchino Audio Marriner10 and the AC outlets are four Furutech Nano Crystal Formula duplexes. Four Cardas ground posts of solid copper are also provided; not provided is an incoming AC cord, though the AC Nexus's distributor will bundle it with a 6' EinKlein David cord for a total of $28,000. Thus equipped and used in MF's reference system, atop a Harmonic Resolution Systems isolation platform (SMc Audio suggests that the AC Nexus is sensitive to vibrations), the AC Nexus coaxed from MF's gear a welcome degree of serenity, "Along with a butter-textured sweetness of sound." But, as Mikey wrote, "overall, it was too smoothed-over for me, too romanticized." Replacing the EinKlein David cord with an AudioQuest Dragon resulted in a more "open" sound. (Vol.41 No.6)

Audience Adept Response aR12-TS AC power conditioner: $8995
The Adept Response provides power-factor correction, RF noise filtering, transient suppression, and 12 Hubbell high-conductivity power outlets. Each outlet is isolated from its input by one filter, and further isolated from the other outlets by a combination of two additional filters, allowing an entire audio system to be plugged into a single AR. BD noted a profound overall improvement in his system's performance, characterized by enhanced clarity, precision, low-level detail, image definition, soundstage size and depth, and tonal density. "A thoroughly thought out, well-designed, nicely executed manifestation of all that's currently known about power conditioning," said BD. "TS" changes from the earlier aR12 include: a new, larger ground with connections welded rather than bolted; Teflon capacitors throughout; and the use of monocrystal copper wire on the Teflon caps. With the aR12-TS in BD's system, dynamic transients expanded, resolution of low-level detail significantly improved, soundstages opened up, images became more dimensional, and voices took on additional harmonic richness. "The Audience aR12-TS is the best power conditioner I've heard," said BD. (Vol.30 No.4; Vol.34 No.10; Vol.35 No.1 WWW)

Audience powerChord: $539/6ft
"The wonderfully flexible powerChord, too, was a winner, significantly cleaning up the sound by lowering the noise floor, opening up the space between instruments, and significantly improving the system's resolution of low-level and inner detail." Though BD's reference, Synergistic Research's AC Master Coupler, offered better senses of space and ambience, the Audience was very nearly as good and much easier to use. (Vol.25 No.8 WWW)

AudioQuest Dragon Source AC cord: $4400/1m, $3300/additional meter
High-current version: $5400/1m, $4300/additional meter
The top models of AudioQuest's power-cord lineup, the Dragons are available in two types: Dragon Source ($3400/1m), intended for source components, and Dragon High-Current ($4400/1m), intended for use with power amps, AC-power regenerators, and other products that draw higher-than-average current. All Dragon models are made with a combination of solid silver and solid copper conductors, and feature AudioQuest's battery-powered dielectric bias system (DBS). After fitting his system with Dragons of both sorts, MF reported "a major improvement in the overall sound" and decided to buy them: "In the context of my audio system, based on what I hear every day, it's well worth it." (Vol.41 No.5)

AudioQuest Niagara 1000 AC conditioner: $999.95
Although it lacks the Niagara 7000's isolation transformers—things known for being bulky and expensive—the far less costly Niagara 1000 has the same "ground-noise dissipation" system and "ultra-linear noise-dissipation" technology as AudioQuest's well-reviewed flagship product. The result is a 20"-long, six-outlet, dark-chromefinished power strip that, in the words of HR, lifted veils: "isn't that what a $1000 power strip is supposed to do?" Herb concluded that the Niagara 1000 "might be the single most important, most high-value component I've auditioned for Stereophile." JA was also impressed by the unexpected manner in which the Niagara 1000 cleaned up the sound of his system. (Vol.40 No.4 WWW)

AudioQuest Niagara 5000: $3999.95
KR, who admits to many years of skepticism about the audible advantages claimed for power conditioners, has had a change of heart, evinced by his use of the words love and Niagara in the same sentence: "I love what the Niagaras 5000 and 1000 . . . have done for the sound of my system." At half the price and less than half the weight of AudioQuest's flagship Niagara 7000, the Niagara 5000 differs from it primarily in lacking the Dielectric-Biased AC isolation transformers on its eight noise-dissipation outlets. (See entries for the Niagara 1000 and 7000 elsewhere in this edition of "Recommended Components.") Bolstered with some of AudioQuest's NRG Edison AC outlets ($149 each), the Niagara 5000 compelled Kal to write that "the noise from [my] tweeters was reduced, and the noise from [my] woofers was now completely inaudible." And there you have it. (Vol.40 No.9 WWW)

AudioQuest Niagara 7000: $7999.95
Billed as "a complete rethinking" of AC distribution, the AudioQuest Niagara 7000 is a power-conditioning accessory that provides a total of 12 AC outlets: four hard-grounded high-current outlets, plus eight others divided into two groups of four, each said to be 100% isolated from the other and from the four high-current outlets. Inside this attractive 81-lb box are circuits comprising AudioQuest's Ultra-Linear Noise-Dissipation technology, six banks of direction-controlled ground-noise dissipation, and AC isolation transformers to which AQ's trademark Dielectric-Bias System (DBS) has been applied. Although MF described the Niagara 7000's outlets as "the most difficult to use I've ever encountered," owing to their sheer grip, he was impressed with the Niagara's effectiveness, which he regarded as being on a par with that of his Shunyata Research Hydra Triton v2 and Hydra Typhon distributors. Each had its strengths, MF said, noting that "the Niagara 7000 better resolved fine detail and threw a deeper, more expansive soundstage." (Vol.39 No.2 WWW)

AudioQuest NRG-X3 AC cord: $99.95/6ft
The NRG-X3 three-pole AC cord uses strands of long-grain copper for its semisolid, concentric-packed conductors. SM connected the NRG-X3 to the Emotiva ERC-2 CD player and heard a cleaner, brighter top end; faster, more assertive attacks; and longer, lovelier decays. "The AudioQuest NRG-X3 delivered more music, made more sense of the music, managed to more fully convey the artists' intentions, and made me a happy guy," he said. (Vol.35 No.1 WWW)

AudioQuest Tornado AC cord, High-Current Version: $1199.95/1m; +$250/additional meter
Source Version: $949.95/1m
When HR replaced his Pass amp's standard power cord with the High-Current version of AudioQuest's stiff, three-conductor Storm Tornado, he noticed "a change in the fundamental shape and tone character of the music coming out of my speakers. Instruments and voices seemed stronger, more three-dimensional. A sleeping dog would have been startled by these differences." Inversely, when Herb replaced the Tornado with a $1 generic cord, he described the results as "like putting on scratched sunglasses and a wool coat on a hot day." That said, HR reported that, with the cheap cord, one of his favorite recording artists endured in having "a naturalness of tone and temper . . . I didn't need a Tornado to enjoy his music." (Vol.41 No.8 WWW)

Ayre Acoustics L-5xe power line filter: $2450
In an attempt to dissipate unwanted high-frequency energy riding on the AC line as heat, the L-5xe, built into the same case as Ayre's P-5xe phono stage, the L-5xe line filter uses a coil of wire wrapped around a nonferrous core for each of its four AC jacks. "Its slight softening effect seemed to improve image palpability, three-dimensionality, and midband texture," said MF. However, the Ayre's "pleasing romanticism" lacked the believability of the faster and more detailed Shunyata Hydra 2, he felt. With the L-5xe in his system, JM noted a taller, wider soundstage and sweeter highs, with no loss of resolution. "Without question, the L-5xe made the system more listenable," he decided. (Vol.30 No.7, Vol.36 No.10 WWW)

Brick Wall PW8R15AUD surge protector: $289
This small, solid, black block is a series-mode surge protector rated for 15A loads and comes equipped with eight outlets in four filtered banks and a captive 14-gauge AC cord. Gave KR the sense that his equipment was safe from catastrophic insult without changing his system's performance whatsoever. (Vol.28 No.5 WWW)

Environmental Potentials EP-2050 Waveform Correction Absorber: $729.99
The EP-2050 provides protection from AC-borne noise by means of a tracking filter, and uses a metal-oxide varistor to clamp and absorb surges. KR: "Examination of my house's line voltage on an oscilloscope revealed a smoother, cleaner 60Hz signal than before." (Vol.28 No.9 WWW)

Kimber Kable PK10 BASE PowerKord: $249 1.5m (5'); longer lengths available at $86/m
ST used Kimber Kords throughout his system, and noted tremendous differences with a Jadis Defy-7. But try before you buy, he warns. (NR)

Kubala-Sosna Elation AC cable: $2000/m, $500 each additional meter
A JA favorite. See "Interconnects." (NR)

Kubala-Sosna Emotion AC cable: $1250/m; $350/additional meter
A KR favorite. See "Loudspeaker Cables." Add $300 for each additional meter. (Vol.29 No.7 WWW)

Luna Mauve AC Cord: $1800/2m
Luna Orange AC Cord: $1200/2m
A new company from Quebec, Luna Cables designs and manufactures four lines of cables: in order of ascending cost, Luna Orange, Luna Mauve, Luna Red, and Luna Black. In all Luna cables, the conductors are old-style tinned copper—in some, the conductors are actual new-old stock tinned copper from decades ago—and Luna eschews polymers in favor of natural materials, such as the hand-dyed cotton used as an outer sheath on all of their models. Designer Danny Labrecque is a tube-and-vinyl aficionado and a longtime Shindo Laboratory dealer, and Luna's résumé suggests that, while not specifically intended as such, their interconnects, speaker cables, and AC cords will jell with systems influenced by vintage-audio values. That's what attracted the attention of AD, who was impressed by what he heard. In particular, AD flipped over Luna's humblest power cord—remarkable, since he seldom has much use for aftermarket AC cords, period. From the Luna Orange series, it sells for $900 CAD for a 2m cord. When he tried the Luna Orange AC cord on his Shindo Haut-Brion power amplifier, it was, he said, "as if I'd found, somewhere in my system, a theretofore undiscovered knob labeled Vividness, and had goosed it up a couple of clicks." (Vol.39 No.8 WWW)

Nordost Qbase QB8 Mark II: $1599.99
Of this AC strip's eight outlet sockets, only the one at the center of the strip goes straight to ground. For the remaining seven, resistors are inserted between the sockets and the ground in an attempt to reduce the noisy currents that can come from having multiple ground points of differing potentials within the system. (Vol.32 No.12 WWW)

Nordost QKore grounding units: $2499.99 (QCore1); $3499.99 (QKore3); $4999.99 (QCore6)
Intended to serve as a manufactured ground reference, Nordost's QKore Ground Units contain a "low-voltage attractor plate" made of a patented inorganic alloy, intended to avoid the variables—temperature, humidity, soil composition, phases of the moon—that can compromise the electrical grounds of most households. QKore Ground Units are equipped with QBase Ground gold-plated binding posts and supplied with silver-plated copper QKore Wires. Three versions are available: QKore1 ($2499), which has one QBase Ground terminal and one 2m-long QKore Wire, and is meant to ground the user's primary distribution block/AC power conditioner/etc; QKore3 ($3499), which has three QBase Ground terminals and one 2m-long QKore Wire, and is meant for grounding audio components; and QKore6 ($4999), which combines in one box the QKores 1 and 3, and comes with two 2m-long QKore Wires and extra grounding terminals. After living with all three, JVS declared that he couldn't imagine the serious enthusiast who would choose to be without the "markedly 'blacker' backgrounds, increased transparency and detail, more vivid colors, and greater overall veracity" they brought to his system. (Vol.42 No.1 WWW)

Nordost Valhalla 2 AC power cord: $5249.99/1m
See Interconnects.

PS Audio DirectStream Power Plant 20: $9999
PS Audio DirectStream Power Plant 12: $4999
The largest of PS Audio's Power Plant AC regenerators, the 96lb P20 provides 16 outlets and has a peak load capability of 3600VA. Like previous Power Plants, the P20 can output a pure sinewave, with adjustable amplitude, or it can alter the waveform in ways that PS Audio says can improve the sound of the system connected thereto—a palette of adjustability the manufacturer refers to as MultiWave. JCA found that MultiWave adjustments had less audible effect than the introduction to his system of the P20 itself; of the latter, he wrote that going from a Wiremold power strip to the P20 was "one of the biggest changes I've heard when switching out components (loudspeakers excepted), and easily larger than the differences I heard the last time I compared two preamps." In a followup, JVS praised the P20 for helping get the most out of the Verity Audio Monsalvat Amp-60. "As good as the system had sounded with the [PS Audio PowerPlant] P5," wrote Robert Deutsch, "with the P12 there was a major step forward in overall realism. With no change in volume setting, the sound was more dynamic." With his McIntosh MC275LE, The midbass-to-low-bass region was clearer, with bass drums and timpani seemingly having a more solid foundation, and transients generally having crisper onsets and more rapid decays. The MC275 LE seemed to lose some of its "tubey" characteristics—it sounded more neutral, more like the real thing." (Vol.41 No.11, Vol.42 Nos.4 & 5 WWW)

Shindo Mr. T. isolation transformer: $2195
Just as Seth Brundle, the protagonist of David Cronenberg's The Fly, set out to purify his body by sending it from one teleportation pod to another, so are certain types of transformers designed to purify AC line voltage by sending it from one coil to another via electromagnetic induction: The desired 60Hz AC makes the trip, but the higher frequencies, which our playback gear regards as noise, get left behind. The Shindo Mr. T is one such isolation transformer: a massive Haruna Denki transformer mounted inside a steel enclosure 9" wide by 6" high by 6.25" deep, painted in Shindo's trademark shade of metallic green and fitted with one IEC input and six ceramic AC outlets. A Shindo power cord—these are intentionally slim and bereft of a ground plug—is included. The Mr. T brought a number of refinements—including greater melodic ease and a lessening of artificial texture—to AD's system, which includes a Shindo preamp, amp, and interconnects (and, at times, a Shindo-modified Ortofon SPU pickup head). It also worked wonders with AD's Garrard 301 turntable, revealing in music a better sense of momentum and allowing "tempos [to seem] quicker—although pitches were unchanged." (Vol.41 No.7 WWW)

Signal HiFi SignalCable 20A MagicPower AC cord: $79/3'
KR came right out and said it: "Of all possible system cables, the one that I believe has the least potential to influence a system's sound is the AC power cord." He also spoke of chafing at the idea of premium-price cables that are too inflexible to use behind his equipment rack. Enter the SignalCable 20A MagicPower cord, based on 10 AWG stranded, high-purity copper, with hospital-grade Marinco terminations. (The 20A connectors are optional at no extra cost.) As of this writing, KR was considering buying more of them. (Vol.41 No.3 WWW)

Torus Power RM20 AC power isolation unit: $3499
Torus Power's Power Isolation Units (PIUs) combine surge suppression with massive toroidal transformers to provide AC power conditioning and protection from voltage surges. The RM20 uses a single 2400VA toroidal transformer to supply 120V and 20 amperes to the 10 AC outlets on its rear panel. It has a 20A circuit breaker for its On/Off switch and uses a 14AWG detachable AC cord rated at 15A/125V. "The PIU greatly enhanced subtle details of tone, timbre, and imaging when dynamics were extreme or volume was loud," said LG. CS20 version has 17" faceplate (silver or black); also costs $3295. (Vol.31 No.1 WWW)

Torus Power TOT AVR power conditioner: $2499
The TOT AVR power conditioner, which has at its heart a sizable isolation transformer, also offers an Automatic Voltage Regulation (AVR) system designed to maintain a stable voltage of 120V, ±5V, within a range of 85135V. The TOT AVR can also be had with Torus Power's Series Mode Surge Suppression (SMSS) system—a $250 option that, in units sold in the US, clamps the voltage instantly if it rises more than 2V above 135V. LG found that the TOT AVR was not up to the current demands of his 400W monoblocks (Torus makes other, more rugged conditioners), but that it otherwise "improved musical detail and three-dimensional imaging for a wide range of music," along with providing the peace of mind of knowing that his gear was safe from lightning. (Vol.40 No.3 WWW)

Triode Wire Labs American Digital AC cord: $499 up to 5'
The High Power Digital American power cord was reportedly designed for power amps, power regenerators, power conditioners, and power bars: a theme emerges. Nevertheless, HR began his time with Triode Wire's cord by using it with digital source components, including his Schiit Audio Yggdrasil D/A processor, and was impressed: "I was surprised to hear more even more vigor, more distinctly drawn images, and a lot more physicality." A few days later he reinstated the Schiit's own stock cord, but after playing only two CDs "became impatient" and went back to the Triode Wire Labs. That said, when he tried the Digital American with his Pass Labs solid-state amp, he found the improvement less remarkable than with the more expensive AudioQuest Storm Tornado cord. (Vol.41 No.8 WWW)

Wireworld Platinum Electra power cord: $1700/1m
Compared to the more expensive Shunyata Research ZiTron Anaconda, the Platinum Electra sounded less vivid and less natural, said MF. (Vol.36 No.11)

Time for Stereophile to review the Denafrips flagship Terminator DAC (under $5k) :-) ........

Kempff's picture

Audioquest Nightowl Carbon (and its Nighthawk sibling) have been discontinued.

There's a new version of the Chord Mojo? Do you know something no one else does?

Bogolu Haranath's picture

AQ NightOwl Carbon is listed under Class-B headphones :-) .......

Kempff's picture

That’s my point. Discontinued items aren’t supposed to be listed.

Bogolu Haranath's picture

May be the people who worked on the list are dis-connected :-) ........

Jim Austin's picture

When we contacted companies about changes in their product lines, as we do before every Recommended Components issue, we were told by AudioQuest that the NightHawk and the NightOwl were still current products.

As for the Mojo, the reason given for its deletion from the list is in error--my error. It is the Hugo, not the Mojo, that has been replaced. The Mojo was deleted because it was last auditioned by a Stereophile writer in the February issue, 2016. Unless awarded a star, components typically "age out" after about three years.

Jim Austin, Editor
Stereophile

Kempff's picture

I guess one hand doesn't know what the other is doing at AQ. They sent out a letter to dealers over a year ago announcing that they were "leaving the headphone category," and they stopped producing the nightbirds at that time. But their website still features them as if they're current.

I'm not sure I understand about the Mojo, though. There are quite a few things on the RC list that were reviewed before the Mojo and don't have stars -- the Audeze LCD-X and Senn HD-650, to pick a couple from the same page. Besides, the Mojo surely deserves a star if anything does: it's a classic, sounds fantastic, and has no competition at its price point. It was the RC listing and JA's review that convinced me to take the plunge, and I've loved it ever since.

Jim Austin's picture

Thanks for your note. Well, the HD-650 should have a star, and I'm going to give it one; there aren't many headphones (HD-600 to name one) that have been around as long and still perform well. In any case, I own a pair, and I think JA1 does, too. As you can read in the intro to the section, we keep things on the list if a reviewer has recent experience and still finds the product worthy. The LCD-X is an example of that: JA owns a pair and uses them often.

That's the general case: Products that were reviewed longer ago than the Mojo but still on the list are there because they are in some reviewer's system.

I've never heard the Mojo, but based on its reputation, I certainly respect it. Whether it's a "classic" is of course a judgment call; smart people can disagree.

Best Wishes,

Jim Austin, Editor

to "excellent" ?

Are some reviewers assigning the Excellent designation but not quite meaning it unless the "truly" adverb precedes the critical adjective? Is this a "secret" writers code word for some reason ?

Why do people feel the need to crutch support their declarations with clumsy adverbs?, seems like it dilutes the most important concepts and fosters mistrust of the Writers intentions.

Those dam Brits have taken to say'n "to be honest" or "if I'm honest" . ( We don't see it here, thank you. )
Feels like the Brit leading off with "If I'm honest" is someone I shouldn't be listening to. ( especially if it's coming from a Religious Minister that buys a series of my Sunday performance Sermons ).

My Audio Importing, Manufacturing & Retailing experiences reveal these Recommended Component Issues to have critical influence in the buying decisions of Audiophiles. Your gifted "fiancé of audio adventures" ( Mr.HR ) is probably the most influential man of letters in this here entire Industry. Mr.Steve G. is souring into Cassey Neistat territory with his Audio related YouTube dailies, big hair & colorful shirts. ( he only needs an electric scooter to ride the now-Empty Streets of Manhattan ) The NEW Steve G. is makning 33.3 look like its soooooo Old-School tired. Of course, I approve.

I can't thank you.

Of course you proffer dam good advice, as usual.

I'm something of a Maverick Brand Ambassador for Schiit & PS Audio ( although either Company would & should say that I'm strictly out-on-my-own and not part of their operations ) I think that Mr.s Stoddard and McGowan are both men of high integrity ( maybe even including M.Moffat who might be a horrible smart ass and proud of it )

I was once a Dealer for PS Audio ( 1980s ) and Tyll introduced me to Schiit back in 2011. Both outfits manufacture in the USA, service their products, answer customers, make A+ level products and price sensibly. What's not to like except for Schiit's dam Name and their stupid rear mounted power switches.

As far as those UBIs are concerned, the Corporate worshiping donkeys may not allow we civilians the same life saving financial treatment being lavished on their sponsoring donor Class. Boeing to accept $60 Billion after ruining their financials with the 787 and 737 mismanagements.

Fingers crossed on those $1,200 ea. with $5,000 per family, I'll be investing in Color changing LED Lighting.

Ortofan's picture

... Maverick Brand Ambassador for Schiit Audio - and since Messrs. Stoddard and Moffat seem to know their way around tubes, as well as transistors - perhaps you could suggest to them that they design a variation of the Vidar power amp with a vacuum tube front end. It could effectively be a budget version of the PS Audio BHK amp.

I'm certain that Mr.Stoddard would entertain your own personal inquiry far more than they would value my nudging suggestions which typically get tossed ( like my standard insistant demand for ALLLLL dam power switching be located on the dam FRONT panel AND! Dammit, change the Brand Name to Stoddard & Moffat like any respectable Company would normally do!!!

I love your idea for Product Development Improvements. ( go ahead and nominate yourself to Schiit's advisory board, I'll second it)

Are you sure about Moffat and tubes ? I wonder if he's cooking up a nice tube DAC?

Your idea of a tube DAC is a smart idea for S. Audio ........ They could offer that DAC with a choice of tube or transistor output ......... They could also offer a choice of multiple digital reconstruction filters for that DAC :-) ........

tonykaz's picture

Why does it need multiple reconstruction?

I suspect that we are already past the point where DACs feature discernible sound quality differences, although professionals like Bob Katz carefully choose converters and can hear details beyond "normal" amateur listeners.

But...

... for the sake of outlandish Pricing, Schiit could offer a DAC made up of ONLY Tubes, much like the very first IBM Computer needing a very large room. Price it at, say..., 3 Million Dollars. Lets give em sumpt'n to talk about.

Dear Misters. of Stereophile, it seems to me that they have made a mistake in removing the DAC Bryston from the list, since Larry Greenhill has them within his teams for his reviews, as well as other components of Bryston. His last review was on February 27, 2020. You can't say you haven't been auditioned in a long time.

Just curious how that decision is made? I have a VTA 120 from Bob Latino and it too can be purchased fully assembled--great amp for the money (along with his mono-blocks)--surely they along with a couple of other similar amps deserve attention.

I am wondering why the B&W 702 S2 are considered “Full Range” while their specifications don’t go to 20 Hz. Stereophile’s review measurements also don’t support this categorization. If these really aren’t “Restricted Extreme LF”, the same should apply to the Revel Performa F228Be.

This seems arbitrary to even have Restricted Extreme LF categorization for the other classes unless there are different requirements for them?.

It is not very clear (at least to me) how items rated in one class are subjectively considered to be superior performers to those in the class below. To clarify this it would be helpful in each case to include a small blurb in the comments for each item not considered to be in class A as to why they were not included in the class above. For example the comment for an item in class B would say " Misses class A because in all systems tested it lacked the ultimate resolution of the lowest ranked item currently considered to be in class A" or "Is slightly too sweet or bright to be considered neutral".

In some cases the reasoning can be gleaned by careful reading of the reviews (and perhaps that is Stereophile's intent), but in many cases it is simply not clear.

As a case in point, consider the case of the Kef Reference 5. It is rated as class B while the LS50 is rated as class A LF. However a reading of the Reference 5 review specifically with comparison to other speakers (eg. Magico) currently listed as class A provides no clue to the reason for the ranking especially relative to the ranking of the LS50. Yes, the Reference 5 appears to be slightly sweeter than other class A speakers, but we are also told that its high end performance is similar to the class A Magico.

Now I have heard both the LS50 and Reference 5 in various systems. I also own the little brother to the Reference 5, the Reference 1. It is my opinion that there is no sane person who after hearing all three who could realistically make the case that the LS50 is anywhere near the performance of either Reference speaker. This opinion appears to be supported by any objective testing I have seen. How then does Stereophile explain this discrepancy?

Stereophile owes it to its readers to explain such anomalies as it risks casting doubt on the legitimacy of the Recommended Components list. Perhaps there is a valid reason in the example provided. If so, I would like to hear it. Your general comments in the "How We Do It" section does not appear to cover this.

Hi! Stirful & other text addicts. I wandered into good sound visiting a surviving friend who ran off to Paris, France after he got his PHD at the University of Minnesota to teach Romance Languages at the Sorbonne. We are both offline (Text-talk for too old for anyone to care that he is now (Class
D) a dread illegal alien in France) after running Sorbonne until they demanded he retire. He has since married his lover in this US of A, is free of her homeland, China. They had visited her family in China and were happy to get their marriage approved. Families are perhaps as picky as loyal readers of this fine publication, even online.I HAVE UTFERED
