2014 Recommended Components Powerline Accessories

Powerline Accessories

APC AV S15BLK: $730 w/battery backup ✩
"The S15BLK is a comprehensive power source, conditioner, and controller that features extensible external power and isolated EMI/RFI filtration for each of its outlet banks. Voltage regulation is accomplished electronically and without the hysteresis or rebound problems of slower, motor-driven compensation. Protected even the heaviest of KR's loads while also eliminating gray colorations and intermittent chassis vibration. "The S15 made the bridged eVo6 into an even better power amplifier—a super amp." (Vol.28 No.9 WWW)

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 3 US AC power strip: $35
AudioQuest's sturdy little 3 US has three standard three-pronged power outlets and accepts a standard IEC power cord of any length and girth. "Plug in a good cable and you have a serious extension cord that will distribute AC where you need it," said KR. "Like having a power strip in your back pocket. You never know when you will need it," he sums up. (Vol.35 No.12 WWW)

AudioQuest NRG-X3 AC cord: $99/6ft
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)

Ayre Acoustics L-5xe power line filter: $1500 ✩
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: $259 ✩
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)

CablePro Noisetrapper NANA power strip: $350 ✩
Manufactured by Wavelength Audio Video and available at most Naim Audio dealers, the Noisetrapper NANA is an eight-outlet power strip featuring 12-gauge silver-plated OFC internal wiring, silver-soldered connections, and a hardwired, shielded power cord, all built into a nonmagnetic enclosure, and devoid of LEDs, MOVs, and filters which might corrupt performance. Plugging his entire system into this one strip, Art found "unambiguously good" performance: "My system was simply easier to listen to, and required less nervous energy on my part in order to convince myself I was hearing music." As of 2013, 12 gauge stranded UP-OCC wiring adds $100, Furutech high performance IEC inlet adds $27.35, passive noise reduction package adds $30. (Vol.29 No.3 WWW)

Environmental Potentials EP-2450 Home Theater Power Supply: $1025.21
Environmental Potentials EP-2050 Waveform Correction Absorber: $728.99 ✩

The EP-2450, a lightweight, full-size chassis, has eight unisolated AC outlets that can pass 20 amperes of HF-filtered, ground-filtered, surge-protected AC, and comes equipped with a filtered and surge-protected coaxial line. KR used the EP-2450 to rid his system of noise generated from digital amps. "Reduced amp noise to effective inaudibility!" The E-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)

Fono Acustica Sinfo power distributor: $9995
Made in Germany, the Sinfo is an attractive six-outlet power strip made of solid Panzerholz, a natural wood material said to protect against vibrations and electromagnetic-wave contamination. It uses Oyaide's top-of-the-line outlets and power inlet; the IEC blades are trimmed down from a phosphor-bronze slab, hand-polished, and plated with a combination of platinum and palladium. The outlets are connected with exotic, thermo-treated wire, and the Sinfo contains no capacitors, inductive filters, or transformers. With his gear plugged into the Sinfo, the sound of MF's system was consistently lusher, richer, and sweeter. Expensive. (Vol.35 No.12)

Furman IT-Reference 20i power conditioner: $3699 ✩
Furman Sound's top-of-the-line power conditioner provides four duplex outlets offering balanced and power-factor–corrected AC, as well as two duplex outlets offering unbalanced power for high-current-draw power amplifiers. JM: "The IT-Reference 20i is built like a tank, and worked flawlessly. It brought a slight lowering of the noise floor without any reduction in dynamics." (Vol.30 No.10 WWW)

GutWire B-16: $99/5 feet $$$ ✩
Uses Schurter and Leviton connectors on multistranded, oxygen-free copper wire. With the B-16 in place, JM noted improved image focus and clarity. "A great value," he said. (Vol.31 No.10 WWW)

HiFi-Tuning Silverstar/Gold fuses: $39.95–$59.95 each ✩
These German fuses, distributed in the US by Ultra Systems, have silver filaments, ceramic bodies, and gold-over-silver terminations. Mikey replaced the cheap fuses in his Musical Fidelity kWP preamplifier and was rewarded with a subtle but noticeable improvement in smoothness and coherence. The HiFi-Tuning fuses worked well with both the Onkyo A-9555 and PS Audio GCC-100, imparting a clearer, more dynamic sound, with crisper transients, said RD. The element of the HiFi-Tuning Supreme fuse ($59.95, small; $89.95, large) is 99% silver impregnated with 1% gold. Its case is of ceramic rather than glass, for better resonance characteristics, and is cryogenically treated. Installed in the PrimaLuna ProLogue Premium integrated amplifier, the Supreme fuse created "a marked increase in clarity," said RD. Go figure! Available in various sizes. (Vol.30 Nos.2 & 9, Vol.35 No.5 WWW)

JPS Labs Aluminata AC Cable: $3999 ✩
The Aluminata AC has three 8-gauge Kapton-insulated conductors and uses a Wattgate plug and IEC connector, both with gold-plated contacts. Along with the matching interconnects and speaker cables, the Aluminatas "brought a new measure of spaciousness, scale, smoothness, heretofore unimagined detail, and overall musical ease and naturalness to my music system," AD enthused. KR agrees with AD that the expensive Aluminata lowers his system's noise floor. (Vol.30 No.4 WWW; also see CS's VTL review in Vol.25 No.11)

JPS Labs The Digital AC-X Cable: $399 ✩
Uses "very-high-purity" stranded copper conductors, insulated to a 300V rating and said to contain a special compound that absorbs and dissipates high-frequency energy. AD: "The Digital AC endowed the music with a better sense of flow and a smoother, more 'liquid' presentation....The sound was more open...with an easier, more natural sense of movement from note to note....The performance as a whole also seemed more dramatic and, in some spots, downright louder." He purchased The Digital AC to use with his Sony SACD player. Current "X" version has updated capacitors. (Vol.26 No.4 WWW)

Kimber PowerKord 10: $280/6 ft, other lengths are available at $25.00/ft. ✩
ST uses Kimber Kords throughout his system, and noted tremendous differences with a Jadis Defy-7. But try before you buy, he warns. (NR)

Kubala-Sosna Emotion AC cable: $1100/m; $300/additional meter
A KR favorite. See "Loudspeaker Cables." Add $300 for each additional meter. (Vol.29 No.7 WWW)

Quantum Resonant Technology Qbase QB8: $1399.99
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)

Shunyata Research Hydra Triton power conditioner: $4995
The Hydra Triton power conditioner is the first Shunyata Research product created using the company's new Dynamic Transient Current Analyzer, a low-impedance power source that simulates the power grid and measures the effects of powerline accessories on a hi-fi system. The Triton offers four pairs of AC outlets, each using brass with a high copper content for the conductors, and employs Shunyata's new Multi-Phase Differential Array, a system of 30 microfilters, each aimed at specific noise components. With the Triton in MF's system, music sounded louder and cleaner and was more transparent, spacious, and detailed. "There's no trade-off," said MF. (Vol.35 No.1)

Shunyata Research Triton power distributor: $4995
With the Triton in his system, MF noted blacker backgrounds, more low-level detail, and an enhanced sense of three-dimensionality. Add the Typhon for $4995, which, partnered with Shunyata's Triton, further blackened backgrounds, further enhanced low-level detail, and further expanded the sense of three-dimensionality, said MF. (Vol.36 No.11)

Shunyata Research ZiTron Anaconda power cord: $2995/1.8m
Compared to the less expensive Wireworld Platinum Electra, the ZiTron Anaconda sounded more colorful and realistic, said Mikey. (Vol.36 No.11)

Shunyata Research SR-Z1 wall outlet: $95
A JM favorite, this heavy-duty duplex outlet has a vented case for heat dissipation and uses highly conductive brass connectors. (Vol.36 No.10 WWW)

Shunyata Research Venom Power System
The Venom system consists of Shunyata's PS8 eight-outlet power-distribution strip ($695), three models of Venom power cords ($75–$295/1.75m), a Venom HDMI cable, and the Venom Defender plug-in noise filter with surge protection ($195). Optional stainless-steel spikes ($200) replace the PS8's stock rubber feet. Housed in a handsome enclosure of brushed stainless steel that's meant to sit on the floor beside or behind an equipment rack, the PS8 uses cryogenically treated Hubbell outlets, oxygen-free copper wiring, and a Carling Technologies hydraulic-electromagnetic circuit breaker. The Venom Defender contains a thermally insulated metal-oxide varistor that provides 22,000 amps of surge protection. With the Venom products in his system, JM noted a significantly lower noise floor and more easeful overall sound. "Highly recommended," he said. (Vol.36 No.12 WWW)

Silver Circle Audio Pure Power One 5.0 isolation transformer: $5500 ✩
Though expensive, the Pure Power One 5.0 includes a 65-lb, 5kVA, custom-built isolation transformer, a proprietary EMI/RF filter, four double-ganged, gold-plated Furutech AC jacks, and a Vesuvius power cord. The PP1 5.0 eliminated noise and increased dynamic range, allowing music to emerge from the soundstage with far greater three-dimensionality. "There was no downside to using the PP1 5.0, only a big upside," said Mikey. (Vol.33 No.8)

Torus Power RM20 AC power isolation unit: $3295 ✩
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 $3000. (Vol.31 No.1 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)

Not a mistake. The Atlas was last included in the April 2013 "Recommended Components" but was deleted from the October 2013 listing on the grounds that it had been almost 4 years since anyone on staff had auditioned it under familiar circumstances.

I've pulled an all-nighter writing, so I gotta be burnt-out.

How to get to the next page in the headphones section.

Is it only this one page???

Just click on the Headphone picture or on the "Headphones" in the list. 

MikeMercer's picture

ThanX Kal!!

That's how I got there.

I think it's only one page - which is a shame.  There's SO much great stuff for John and Co. to cover! Schiit Audio, Cavalli Audio, ALO Audio, Aurelic, JH Audio, Mr. Speakers, and DNA for example. 

John! If you EVER want any help covering the VAST personal audio universe?!?!?

My Sonic Satori Personal Audio Lab!!

BTW - we're havin a BLAST over at Audio360!!

Stereophile has an entire online sister publication dedicated to personal audio, innerfidelity.com. It also has another that covers computer audio, audiostream.com.

ThanX Mike!!  I wonder if you've compared your writing style to Tyll at InnerFidelity and wondered why he has the gig?!?!?!  

In all seriousness, InnerFidelity is great and has covered just about every brand you mentioned, I think.  Tyll tends to shy away from the super-custom year-long-waitlist stuff but I find it a good thing compared to forums full of people who drop $4K on amps like it's nothing. 

I also don't think Tyll posts unboxing vids.

The Sony MA900 headphones have a 70mm driver, just for your information.

Dear Editor:

I read the review of the Musical Fidelity DAC. I am not sure how that qualifies as a "formal" review. Yet, that product is placed in the A+ category? I would think that something that goes into the A+ Category would be thoroughly vetted in order to qualify to be a member of the Best-of-the-best category.

Not buying this recommendation...

Thanks

We include in "Recommended Components" products that have been reviewed in one of our regular columns. Although these reports don't include measurements, they are as rigorously prepared as any other "formal" review in the magazine.

subbanerjee wrote:

You will note that there is the reference "See ST's review in this issue." With all reviews that are published in the same issue as "Recomemnded Components," the rating is provisional.

in the magazine".

Reading through the review, here is the section that refers to the performance of the DAC...

"Compared to the V-DACII, the V90 DAC offers still greater low-level resolutions, superior dynamics, and fatigure-free listening. It does space and place particularly well, and really shines with brass, where lesser DACs tend to turn dull. The Brass Ear would love it."

That's it. And it made it as an A+ DAC?

Come on. As the Editor-in-Chief,  I assume that you question your reviewers when they submit this and want it included in A+. Should you not say, "I don't know Sam, but let's give it a more thorough going over before we put this $299 DAC in A+."?

As you can discern by now, I am not buying this review or your disclaimer that it is a "provisional" rating. I think that a product should have got a thorough going over before it is placed in the rarified air of an A+ rating.

It isn't a disclaimer, just a factual statement. The definitive rating will be published in our October issue listing, following my follow-up to Sam Tellig's review. In the meantime, you are perfectly entitled to your opinion on what we write.

Actually I got this DAC based on recommendations else where. It is properly run in but I did not get the performance of this DAC. It is bright and possibly a tad cleaner but no reason to be A+ product. And yes, it is definetly fatigue-ing. I liked Rega DAC better and Audiolab M-DAC is brilliant though they are a bit different in price range.

The KEF 207/2 is no longer on the list...

The KEF was positively reviewed in February 2008; see www.stereophile.com/floorloudspeakers/208kef/index.html. The R207/2 hasn't been auditioned by a Stereophile reviewer since that review, so, as is our policy, it was deleted a couple of years ago. That is why there is no mention its deleion in this listing. However, as we say in the introduction on the first page: "Where deletions are made, we endeavor to give reasons...But remember: Deletion of a component from this list does not invalidate a buying decision you have made."

We used to highly recommend the Synchrony One, but as with the KEF speaker mentioned above, our review was six years ago - see www.stereophile.com/floorloudspeakers/408psb/index.html - and the speaker was dropped from the listing a year or so back due to none of us having any continued experience with it since the review.

The complete Recommended Components from 2003-2013 can be purchased from our on-line store.

John, it's hard to take a "2014 Recommended Components" list seriously without any mention of Magico S5's, Vitus components, Jorma Prime or Statement cables or Stillpoints isolation devices. Is this the swisse cheese list?

From the introduction to the listing: "Components listed here have been formally reviewed in Stereophile..."

Unlike some other recommended lists, we restrict "Recommended Components" to products that have already been reviewed in the magazine and thus subject to full scrutiny. And there are products from Magico and Vitus included.

That's fair enough John. I'm pleased to see Magico and Vitus make the list! Both outstanding manufacturers.

I would love to read further on your initial article (Sam's Space, I believe) about the Dynaudio Focus 160.  I have heard good things about this product and would like to know of your sound basis for making this speaker a recommended component.

I have searched fruitlessly for this article and it has evaded every type of google search.  Dynaudio mentions the review on its site but, alas, they provided no link either.

Is Stereophile Vol. 35 No. 1 not avaliable online?

Can you send us any kind of html link through this discussion thread?

Thanks.

Is there a reason that this iteration of the list doesn't include any product images? I initially thought that it might just be my tablet, but I get the same wall of text on my desktop and phone as well.

Last year we could include images because we had the time to prepare the Web reprint from the tablet app. Thus year we are both temporarily operating short-staffed and wanted to post the complete Web version as soon as possible after the appearance of the April issue on the newsstands/in subscribers' mailboxes. This meant discarding both images and review URLs, I am afraid.

We could see ubber, ultra and expensive cables on interconnects and speaker cables, but not on digital cables. Is there a reason?

Some cables calls attentions, e.g. Stereolab Master reference 818 BNC/SPDIF, Wireworld Platinum Starlight USB, Kimber KS2020/2120, etc.

Shouldn't the Centrance DACMini CX be listed under this section also given the DacPort is also?

Next month,will be four years since I purchased new, my 5004 matching AV receiver and BDP. The AV receiver has died (processor) and the BD player still sounds great when you can finally get the disc to load (mechanical). On occassions, I have had to give up trying. I was very happy with my entry level setup until it died. I now will try a Fusion 8100 AV receiver as a preamp to a ATI AT2005 amp powering my PSB T6's
