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 WWW)

Audience Adept Response aR12-T4: $11,400 ★
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. Current version is an update of the TS BD reviewed, but JCA judges that the changes, at a minimum, should not reduce performance. (Vol.30 No.4, Vol.34 No.10, Vol.35 No.1 WWW)

AudioQuest Dragon Source AC cord: $4500/1m, $3400/additional meter ★
High-current version: $5500/1m, $4400/additional meter
The top models of AudioQuest's power-cord lineup, the Dragons are available in two types: Dragon Source ($4500/1m), intended for source components, and Dragon High-Current ($5500/1m), 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." MF later wrote, when comparing the Dragon AC cables with another brand that what he heard "was another leapfrog forward producing more transparency (in the sense of the ability to see into the sonic space), more air, and more rhythmic authority. ... Nothing else I've tried ... matches the Dragon AC cord's transparency, quiet, and taut musical grip." (Vol.41 No.5, Vol.45 No.9 WWW)

AudioQuest Niagara 3000 Low-Z Power Noise-Dissipation System: $3300
The Niagara 3000 is an AC power conditioner with two high-current receptacles for amplifiers, five source-component receptacles, AQ's Transient Power Correction (which provides a current reservoir specified to provide more than 55 amps of "instantaneous" peak current), and AQ's Ground-Noise Dissipation System. TG found that with his twin subwoofers powered by the Niagara 3000, "it was obvious that there was less distortion in the signal, and the bass was deeper, more dynamic, and more musical than before." He added that with his system powered by the AudioQuest, the conditioner extracted a "previously unheard level of tangibility" from streamed recordings. FK agreed, finding that the Niagara 3000 added to his system's sound a "closer approximation to in-the-flesh music, heard whole—from top to bottom (low notes to high notes and everything in between), side to side (left channel to right), and front to back (the pinch-me illusion of soundstage depth)." He commented that with the Niagara 3000 there was "a seamless absence of noise—across the frequency spectrum." (Vol.43 No.12, Vol.44 No.8 WWW)

AudioQuest Niagara 5000: $5500 ★
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: $9800 ★
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 81lb 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: $99.95/6' ★
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: $1395/1m; +$300/additional meter ★
Source Version: $1145/1m
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: $309 ★
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)

CAD Ground Control GC1.1: $2250
CAD Ground Control GC3.1: $5500
These passive systems are intended to reduce a broad range of high-frequency noise picked up by and created by electronics, as well as RF noise that gets into connecting cables and components from the AC mains. MF tried the two-socket GC1 and the six-socket GC3 along with CAD cables ($350 each) that connect on one end to the Ground Control units with 4mm banana plugs and are terminated on the other end with USB, RCA, XLR, spade, and 4mm banana plugs. He found with one of his favorite LPs that the Ground Control system resulted in "more delicate" sound but with still well-articulated attack. The background was blacker, recorded strings had more luster, female voices were smoother, and sibilants were more cleanly expressed so that the LP sounded "more 'there' and less recorded." He subsequently wrote that "Now that I've lived with it for another couple of months, I can render my verdict: I can't live without it." (Vol.43 Nos.7 & 9)

Clarus CPB-2 Duet Power Block: $1250
This "well-engineered," two-outlet, high-current power conditioner features a noise-reducing low-pass filter (up to –49dB, 100kHz–6MHz) rated at 30A and utilizes a proprietary technology that Clarus calls "C-Core." Thermal Metal Oxide varistors protect against surges. MF auditioned the Duet with the matching Clarus Aqua AC cable ($549 for 3', $1849 for 12'). With the Clarus in the system, MF found that it produced quieter backgrounds and a somewhat reduced a layer of "haze," this probably caused by high-frequency hash. It also didn't limit dynamics, he found. (Vol.44 No.2 WWW)

Ferrum HYPSOS Hybrid Power System: $1195
This internally complex, programmable power supply accepts 110–240V AC in and can output a user-selectable DC voltage from 5V to 30V at up to 6A. A linear supply feeds a low-ripple switching supply (SMPS) through a single-stage filter, there is a two-stage filter on the output of the switching supply, and the SMPS is followed by a low-noise linear regulator. HR used the HYPSOS with Ferrum's OOR preamp/headphone amplifier—see Headphones & Headphone Accessories—and decided that the HYPSOS "brought new glow, space, and atmospheric vibrancy to everything I played. These enhancements were most recognizable from the upper bass through the top of the female vocal range." (Vol.45 No.2 WWW)

Kimber Kable PK10 BASE PowerKord: $350 1.5m (5'); longer lengths available at $140/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: $1749.99
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: $2749.99 (QKORE1); $3849.99 (QKORE3); $5499.99 (QKORE6)
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: $5999.99/1m
See Interconnects.

Nordost Qsource Power Supply: $2749.99
See Jason Victor Serinus's review elsewhere in this issue. (Vol.45 No.10)

PS Audio DirectStream Power Plant 20: $9999 ★
PS Audio DirectStream Power Plant 12: $5499 ★
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 Follow-Up, 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." Following issues with his AC power, MF found that a Power Plant 20 restored the sound quality of his system. (Vol.41 No.11, Vol.42 Nos.4 & 5, Vol.44 Nos.4 & 5 WWW)

Shindo Mr. T. isolation transformer: $2595 ★
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)

Shunyata Everest 8000: $9500
The Everest is intended to bleed off noise on the powerlines. This is done primarily by Shunyata's "CCI Filter," which is described by Shunyata as using "modules that consist of proprietary multi-stage filters that reduce power-supply–generated noise without the use of heavy transformers, coils, or large capacitors." BD used this power conditioner with a Shunyata Sigma v2 XC ($3250) power cord to connect it to the wall and Shunyata Alpha v2 NR power cords ($2000) between the Everest and his front-end components. (He also used the latter cords for his VTL power amplifiers.) "Casual listening was more than enough to hear the difference: My system sounded significantly better," he wrote. Carefully comparing the sound of the system with and without the Everest 8000, he found that without the Shunyata, "it was as if a slab of smoke or haze was now encasing the performers, who were themselves flat and perhaps even a tiny bit out of focus." With the Shunyata, he "became aware of fine details that simply weren't there before; neither the clarity nor precision required to define them had been present." Summing up, BD wrote "The changes the Shunyata system made to my system . . . weren't subtle. The magnitude of noise reduction was startling. The additional spatial and temporal details revealed when the noise was eliminated made performances richer and more involving and returned a lifelike energy that I hadn't realized was missing." (Vol.44 No.5 WWW)

Signal HiFi SignalCable 20A MagicPower AC cord: $109/3' ★
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)

Stromtank S 1000 battery power source: $15,975
The German-made Stromtank uses a lithium-iron-phosphate battery array with a storage capacity of 1000Wh that can power front-end components for 5–8 hours before recharging. (Its 450VA continuous output power at 77°F is not sufficient for high-power amplifiers.) JVS tried the S 1000 with his source components and experienced greater color saturation and transparency, better integration of orchestral instruments in different ranges, and a less gray background compared with the components powered directly from the AC line. Without the Stromtank, the highs were slightly noisier, lows were shallower, and there was a relative lack of clarity on bass lines. "I'd expected the Stromtank S 1000 to improve the sound of my system, but I never thought it would serve as the missing link to component greatness," he concluded. (Vol.45 No.7 WWW)

Torus Power RM20 AC power isolation unit: $3999 ★
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)

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: $2200/1m ★
Compared to the more expensive Shunyata Research ZiTron Anaconda, the Platinum Electra sounded less vivid and less natural, said MF. (Vol.36 No.11)

I was very surprised to read that the Benchmark DAC 3 is no longer a Recommended Component . In the earlier 2022 edition of Recommend Components , it was an A+ component . Your stated reason for the deletion was because it was not auditioned in a long while . Well why not audition it then ? Also, why is an audition necessary ? It measured as one of the best DACs ever . Why would its measurements change simply because you have not auditioned it recently ? I understand its your policy , but it seems rather unfair to Benchmark that you no longer recommend it for that reason . I believe a much fairer policy would be that a highly rated component should only fall off the recommended list if it is auditioned periodically and you determine that its current level of recommendation is no longer justified based on the factors that you use to include a component of the recommended list .

JRT's picture

Les, toward some light hearted amusement, consider a reductio ad absurdum.

The quoted material below was excerpted from the first version (published 01 May 1963) of Stereophile's recommended components, just the A,B,C rated amplifiers and preamplifiers:

Quote:

Preamplifier-Control Units
A: Marantz 7, McIntosh C-20
B, C: Dynaco PAS-2

Power Amplifiers
A: Marantz 8B, McIntosh MC-60 (footnote 5), Marantz 9A (footnote 5)
B, C: Dynaco Stereo 70

Footnote 5: mono amplifier.

Reductio ad Absurdum... Should the old gear listed above continue as currently recommended gear, or is it best left in its original context in the circa 1963 article? ...and why or why not? ...and is it a much too different set of cases for comparison? ...why? Would that old gear be good fodder for a listing of recommended vintage gear, and is that good subject matter for the current Stereophile readership? These are mostly rhetorical questions, but not all.

JRT's picture

Would you also include the essentially similar PAS-3, and then also the PAS-3X with updated tone controls, and then maybe also Frank van Alstine's improved Super PAS Three, etc.? The original short-list can grow large.

It would be nice if the "title" of the piece recommended was clickable, so one could easily then read the full review of all these thousands of "recommended components" instead of searching like a ???

Just a thought??

I must say I'm surprised to see Perlistens into Restricted Extreme LF category as I thought they were full range speakers.

Kal Rubinson's picture

For most, they will be full range but, as you can see from JA's Fig. 4, the FR is rolling off smoothly below 100HZ such that it will easily mate with a complementary subwoofer. I believe that was Perlisten's intent. That said, unless you are assessing the sound of low, low organ pedal tones, explosions or thunder, the bass from the s7t is clean, powerful and musically satisfying.

Robin Landseadel's picture

There's a lot of Dance Pop/Techno music that gives the lowest octave a workout. Managed to blow out the small bass driver from a Paradigm bookshelf speaker with a Sarah McLaughlan track---"I Love You" from the album "Surfacing"---a quiet ballad with a synth bottom without overtones, so there's pure, deep bass. Another good example would be the work of Bill Laswell, a producer/bass player.

Kal Rubinson's picture

OK but how is this relevant? On the one hand, I am not surprised that one can blow out the small bass driver in a bookshelf speaker. On the other, I doubt if it would do that to the Perlisten.

Robin Landseadel's picture

Blowing out the driver of a Paradigm Atom might not be meaningful save that I blew it out with a track that is low in level and undynamic. More to the point, it sounds like the speakers in question could use a sub. Of course, you pointed out that the speakers in question are designed to integrate well with subs. My Infinity 250 speakers, small floor-standing speakers, also requires a sub for deep bass.

What is meaningful is that there is more to the bottom octave than organ pedals and explosions. Lots of modern productions take advantage of digital recording/playback's ability to record/reproduce the lowest octaves of sound.

Kal Rubinson's picture

Yes, there is a lot more to the bottom end than I cared to mention but the distinction between the small Paradigm Atom and the s7t is that the former needs a sub (or a LP filter) merely to survive wide-band signals while the latter does not.

Did you read my comments about the Garage Door test? I doubt that either your Paradigm or your Infinity could compete with the Perlisten, with or without a sub.

Robin Landseadel's picture

Doubtless. My point was more about program material and really deep bass. In any case, my Infinity Primus 250s are aided by my Sonance Son of Sub. As the system is in a small room, it's probably as much bass as the room can take.

Anton's picture

I like to hit this issue and pretend all my Hi Fi gear is gone and I have to start over with my budget and this list.

Droooooool.. and I'm done FOREVER.

Soulution, MBL... heaven.

KEFLS50W's picture

It will be interesting to see if Stereophile catches up to the focus on active, integrated designs. The relevance of separates seems to be waning in comparison to these sexy and modern designs (many of which are good value to boot) from KEF, B&W, Q Acoustic, ATC, Dali, and others. LS50WII for example gives me access to high quality, high current class a/b amplification I would not have been able to afford with separates. On another note, why are REL subs not listed - they would floor the competition listed in terms of sonics and build quality. Sorry but SVS is a home theater product and KEF KC62 is for kids.
