In 1978, Bill Low began building audio cables for customers of his hi-fi shop. Just two years later, satisfied with his cable designs, Low founded AudioQuest in order to serve the larger audio market. Now, over four decades after that, AudioQuest has become one of the most-recognized brands in all of high-end audio. And it hasnt only been cables driving the company's success. Audiophiles embraced AudioQuest moving-coil cartridges, introduced in the early 1980s, as well as the AudioQuest Music recordings, which began appearing in 1990. Todays AudioQuest catalog has cabling solutions for almost any audio, video, data or power needs. It also includes a variety of audio accessories, from the genre-defining DragonFly portable USB DAC to the state-of-the-art Niagara power conditioners.AudioQuest's motto from the very beginning has been Do No Harm, the company's version of the Hippocratic Oath. To that end, they build components and cabling with the best available materials and technical design to get out of the musical way by inducing the least amount of noise and distortion.
To achieve this goal, AudioQuest focuses on four main design aspects. The first is the use of solid-core conductors. AudioQuest believes solid-core wire to be of superior construction, identifying wire-strand interaction to be a major source of distortion in audio cables. But they also recognize that solid-core conductors are not practical for many applications. Through concentric wire geometry, they developed Semi-Solid Conductor cables, allowing multiple strands to mimic solid-core wires, thus lowering distortion.
AudioQuest also prioritizes the directionality of cables. The company explains that every metal will have scaly, non-symmetrical grain patterns once wire is drawn through mandrels during production. These scales are problematic, allowing radio-frequency (RF) noise to travel along their surface. Fortunately, there is less resistance in one direction and radio-frequency noise will seek the path of least resistance. AudioQuest identifies conductor directionality by listening, which determines the direction that most effectively drains the induced noise from the cable.
AudioQuest's says its use of higher-purity metals reduces noise and distortion. But by carefully mixing metals and conductors sizes, AudioQuest has developed cost-effective techniques to build high-performance, high-value cables at every price point.
Finally, there's noise dissipation. Radio-frequency contamination is ever increasing, and AudioQuest has developed three techniques to combat this. The first is ZERO-tech, which is their terminology for achieving no characteristic impedance for the cable. According to AudioQuest, this technology eliminates the electrostatic field between the high- and low-signal conductors, enabling a consistent octave-to-octave RF noise dissipation. A second technique is referred to as RF/ND-Tech. RF/ND is said to cancel induced RF noise by utilizing a common-mode, phase-cancelling array coupled with proprietary dielectric materials.
To further address noise dissipation, many AudioQuest cables utilize their DBS (Dielectric-Bias System), introduced in 2004, which includes an RF-Noise trap for reduced dielectric distortion and noise. An insulated anode and uninsulated cathode inside each cable are connected to battery packs at the cable's downstream end. The batteries keep the cable's dielectric constantly charged with DC and thereby ensure that the dielectric never drains its energy as distortion. Because the battery packs are attached when the cables are terminated, the cables arrive ready to use. No hundreds of hours of burn-in are required before the cables begin to sound the way they should. AudioQuest argues that the phenomenon of cable break-in is actually a matter of the dielectric adapting to a charged state, and whenever the cable is not being used, the dielectric returns to its uncharged state.
Black Beauty is part of AudioQuest's Mythical Horses Series and incorporates ZERO-Tech noise reduction. To further enhance noise reduction, the RCA barrels are copper-plated, and the RCA plugs are silver-plated red copper. The cables are directional with clear markings on each RCA connector, and the barrels are large enough to allow for an easy grip during installation. The Black Beauty cables certainly live up to their name, having the most luxurious look and feel of all the wires sent in for review.
The Robin Hood ZERO speaker cables use the 72v DBS and Zero-Tech technology to reduce noise intruding on the music signals. The silver-plated red copper banana plugs are cold soldered for better signal transfer. Robin Hood cables are roughly rectangular in shape with rounded edges, and the banana plugs are a bit different than traditional bananas or BFA designs. Beautifully silver plated, the banana plug itself has a small diameter rib protruding from one side. This rib applies the pressure needed to keep the banana plug tightly inserted into the speaker terminals. A pair of Bare Naked Bi-Wire Jumpers are included with the Robin Hood cables to allow users to eliminate the usual brass jumpers included in many speakers with biwire capability. An interesting point to note about the Robin Hood ZERO: they are not intended for biwiring unless the second set of wires used are the Robin Hood BASS cables. AudioQuest states that two Robin Hood ZERO used simultaneously on a biwired speaker will cause a high-frequency spike in the speakers frequency response.
Finally, the Monsoon is part of AudioQuests Wind Series of power cords. It uses Perfect Surface Copper and Long Grain Copper (PSC+) conductors and utilizes AudioQuests RF/ND technology. These power cables are almost 3/4 in diameter and are fairly weighty, but they are not overly difficult to maneuver behind an audio rack. Both plug ends are nicely molded to fit your hand and the IEC end provides a solid grip when plugged in. The cable is flexible enough to route around components but is resistant to rotation of the end plugs, so some extra effort was needed to dress the cables behind the rack.
The break-in process for the cables I used was interesting but thankfully short. On the first day of use, the systems sound was somewhat muted, polite and shy of treble. Still, the sound was listenable, and I streamed some Qobuz playlists to help with break-in. What followed on the next morning was the audio equivalent of the terrible twos in child raising: the midrange took on a shouty tone and the treble sizzled, making listening for enjoyment out of the question. But on the third or fourth day, everything relaxed and serious listening could begin.
After the break-in period, I spent one morning enjoying two favorite piano recordings. The first was a Qobuz stream of Vikingur Olafssons Debussy-Rameau [Qobuz Deutsche Grammophon 24 bits/192kHz] followed by a vinyl copy of Glenn Goulds Bach Vol.6, the Partitas [CBS Masterworks M2 42164]. Aurally, these two recordings are quite dissimilar. Olaffsons recording is slightly distant, like most recent DG piano releases, yet vivid enough to be clear and communicative. In sharp contrast, Gould is recorded very close to the pianos soundboard, almost as if the listener is seated beside him on the bench. His signature moaning and humming are easily heard throughout the recording. Quite a diverse listening session of equally enjoyable performances, and I felt that both recordings were a bit more satisfying with the fresh wiring and power distribution.
One improvement was instantly apparent: I was surprised just how coherent the sound of my Altec Valencias had become. I usually associate coherency with electrostatic panels, Magneplanars, and just a few single-driver, full-range speakers. Ive enjoyed listening to my Altec Valencias for the past eight years, and they have served me well, but coherency is not something I normally associate with them. The bass range is produced by a 15" soft-paper-cone woofer in a large, underdamped cabinet, and treble is provided by a famously energetic 811b metal horn, driven by an Alnico-magnet compression driver. It is a rare moment that the disparate nature of these two transducers sound goes unnoticed, but that was exactly what I was hearing with the addition of the AudioQuest wiring. I could play tracks at higher volumes without stress, and the woofer and horn tweeter blended beautifully. Piano sounds on the recordings mentioned above had tonal consistency across the full spectrum, and the right-hand notes had just the right amount of sparkle without crossing over into harshness. This balance and coherency delivered by the AudioQuest wiring was completely unexpected but very welcome.
During subsequent listening sessions, I noticed that the lowest bass range was tighter and more focused than with my reference wiring. Because of this, bass lines were easier to follow and the timbre of the bass instrument was easier to assess. Along with the tighter bass came a clearer low midrange, which added information about the bass instruments tonality and nuances in the performance. The AudioQuest cables gave an improved apparent sense of speed to my speakers bass response, and recordings of upright bass were generally more powerful and propulsive. For synth and electric bass, I listened to LImperatrices Tako Tsubo [Qobuz Microqlima IDOL 100 24 bits/44.1kHz], a joyous disco-flavored album and the propulsive electronic dance music from Automat on Ostwest [Qobuz Bureau B BB246 16 bits/44.1kHz]. The AudioQuest cables presentation of bass was exciting and toe-tapping on these two dance-oriented albums.
Proof of transient-speed improvement came when I chose a recording by percussionist Colin Currie, teaming up with trumpet virtuoso Hakan Hardenberger on The Scene of the Crime [Qobuz Colin Currie Records-CCR0002D 24 bits/96kHz]. I spent the most review time listening to their performance of Andre Jolivets Heptade, a piece that is as challenging for the listener as it is for the performers. Hardenberger uses multiple mutes (straight, cup and Harmon) in the seven movements, and Currie answers with some explosive percussion bombardment. The trumpet had bite and energy, with plenty of dynamic range.
Additionally, the recordings soundstage was well defined, with each performer standing out against a dark backdrop. Heptades opening snare-drum explosion was suitably jarring, and Hardenbergers melodic answer was smooth and powerful. Ive heard Hardenberger perform live, and the AudioQuest cables did a fine job of preserving his exceptional trumpet tone.
Encouraged by the AudioQuest cables' handling of brass recordings, I cued up Nightfall by Till Bronner and Dieter Ilg [Qobuz Sony Masterworks 24 bits/96kHz]. On their instrumental cover of Leonard Cohens A Thousand Kisses Deep, I was more aware of Bronners alternation between a soft-focus flugelhorn tone for melody lines and a tighter traditional tone for improvisational sections. Bronners soft-focus effect is similar to tenor sax players using subtones for a breathy fuzziness during ballads. A good example of subtones on saxophone might be any ballad by Ben Webster or Coleman Hawkins. Between Bronners flugelhorn tone and Ilgs throbbing low-bass lines, the AudioQuest wires kept me deeply focused on each performers technique and melodic phrasing.
The recording I came back to most often while evaluating the AudioQuest cables was Besame Mucho from Henri Texiers Heteroklite Lockdown [Qobuz Label Bleu LBLV 6743 24 bits/48kHz]. Texiers bass sounded full-bodied, with a warm tone and just the right amount of finger pluck to propel the rhythm of the melody. He was recorded center stage, sparsely accompanied by Gautier Garrigue on lower-pitched congas or djembe drums. The AudioQuest products allowed me to hear that Garrigues percussion was given a different, more spacious soundstage than Texier. There was more reverberation overall and good reverb trails varied according to the size of the drum being hit. At the end of the first verse and chorus, Texier ends his bass solo on a low F just as his son, Sebastien, enters on sax. The AudioQuest bass control and definition made Henris lowest note seem even lower and more powerful than that notes 43.65Hz frequency would indicate. Interestingly, the clarity delivered by the AudioQuest wiring also made it clear that the microphone choice for Sebastiens saxophone rendered his sound a touch synthetic and less natural than the microphones used for percussion. It also became clear that Henri Texiers bass sound and tone were the most realistic on this track.
Coming back to this track after removing all the AudioQuest cabling and reinstalling my normal wires, all the reverberation cues and warm tones were present, but the presentation was slightly different. With my wiring, images were a bit larger, but less defined and a touch more diffuse. The AudioQuest wiring presented a darker background and a more precise instrumentalist placement on the soundstage. The various recording nuances on the Texier album yielded a more natural, engaging listening perspective when the AudioQuest products were in place.
I enjoyed my time with these cables and power accessories from the middle tiers of AudioQuests vast product lineup. As I was packing up the products for return, I thought about which of them I would miss most, which ones I would consider buying for my system. First on the list would be the Monsoon power cords, specifically for use with digital sources. I tried them on four different digital products: my own BorderPatrol DAC SE-i and Neko Audio D100 Mk 2 DACs, as well as a friends Denafrips Gaia DDC and Pontus II 12th. Each time the Monsoon were in use, the sound became smoother and more relaxed. It really was the equivalent of buying a more expensive piece of digital gear. That was particularly evident on my friends Denafrips combo, yielding the best digital sound Ive heard at his house. The improvement was dramatic enough for him to order his own Monsoon cords after our listening session.
The second item I would purchase would be the Robin Hood ZERO speaker cables, largely due to their synergy with my Falcon speakers. I primarily used the Altec Valencia speakers for this review, but I did spend some time with the Falcon LS 3/5as, and Im glad I did. The Robin Hood ZERO speaker cable's effect on the Falcon speakers was quite subtle and took a while to appreciate. The Robin Hood ZERO shifted the tonal center a bit lower, being ever so slightly darker with nicely controlled bass. That infamous LS 3/5a bass bump was tightened a bit, delivering a better sense of pace or apparent speed of bass attacks on floor toms and timpani. And even though the tonality was a bit darker, the little Falcons treble could still fill the room with a spacious soundstage. This is clearly the best cable match Ive had with the Falcon speakers, making it difficult to return to my regular wiring.
A slogan on the AudioQuest website is Doing no harm since 1980, and it reminded me that Ive been using a variety of AudioQuest products on a semi-regular basis since the 1990s. Presently, Im using an older Cougar phono cable, which is a good match for my Ortofon SPU and Denon DL-103 cartridges, and a DragonFly USB DAC with my desktop computer system. Ive come to depend on their neutral sound and reliability.
Reviewing these new offerings from AudioQuest revealed some deficiencies in my present wiring, as well as introduced me to some desirable upgrades. Audiophiles looking to improve their own cabling would do well to check out the AudioQuest catalog. It has a solution -- often more than one -- for almost any wiring need at every possible price point.

Filling out a system with AudioQuest
How many manufacturers can provide all the necessary cabling to achieve a "full loom" of signal- and power-carrying cables? Only a few, and AudioQuest is one of them. You can actually assemble full sets of AudioQuest cables at various price points, extending the full-loom concept to audiophiles with different budgets.
In this vein, AudioQuest actually provided me with more products than those mentioned in the title of this review. In addition to interconnects, speaker cables and power cords, the company sent power conditioning and a full array of digital and analog cables. These products represent a mid-priced tier from AudioQuest's extensive catalog.
The PowerQuest 707 power conditioner ($1299.95) powered my system. This unit has twelve outlets on the rear panel, four of which are designated High Current for amplifiers, and the remaining eight are filtered outlets for source components. The power switch on the front panel has a satisfying clunk when pushed, and a relay inside the 707 turns on the unit almost immediately. The High Current outlets are fed by what AudioQuest calls a TPC circuit (transient power correction), which allows for up to 40 amps of current to be supplied for a period of 25ms. The filtered outlets use differential and common-mode filtering operating from 8kHz up to 1gHz. The PowerQuest 707 has rack-mounting ears available for home-theater installations. AudioQuest includes a dedicated power cord with a low-profile plug, easing installation where space is a concern.
To connect my server to my DAC, AudioQuest provided a Carbon USB cable ($229.95 per 1.5m length). This cables three-layer shielding is actually carbon based, with 5% silver conductors encased in hard-cell-foam insulation.
For analog playback, my tonearm was fitted with a Yosemite tonearm cable ($549) equipped with a DIN connector. This cable uses AudioQuests familiar 72v DBS (Dielectric Bias System). The shield wire extending from the DIN plug is not tightly tethered to the signal cable, as with other DIN phono cables I have used, but I appreciated this design feature because the slack made it easier to attach the grounding spade to my phono stage.
After connecting the Yosemite to a Lounge Audio Copla Transimpedance step-up preamp, a set of Yukon RCA interconnects ($495 per meter pair) completed the connections to my phono stage. Yukon is part of AudioQuest's Rivers Series, one step below Black Beauty in AudioQuests interconnect hierarchy.
I was predisposed to liking the sound of the Yosemite phono cable, because Ive used an older AudioQuest Cougar phono cable for a number of years. I alternate between the Cougar, an Ortofon 6NS-TSW 1010 cable, or a Musical Design cable made for me decades ago by John Hillig, with each sounding a bit different but equally good. Lately, Ive decided that my Cougar is the Goldilocks cable choice for my vinyl setup. It is neither too bright nor too dull, with a way of communicating music and getting out of the way. The Yosemite deviated from this only by being more transparent than the old Cougar, with an ever-so-slight elevation in the low treble. This brought out details in recordings without adding too much sparkle. A good friend just gave me a vintage Ortofon SPU-A, and that lush cartridge found a happy companion in the Yosemite, yielding just the right amount of treble energy and purity. This was even more evident through my old Stax headphones.
Regarding the PowerQuest 707, I wondered if its power-correction capabilities were what was contributing to the especially good microdynamics and transient speed I was hearing, even if my low-power tube amps could not take full advantage of the short-term amperage available from the high-power outlets.
There are a few ergonomic issues to consider with the AudioQuest products. The PowerQuest 707 is designed to be suitable for rack mounting, so its height is that of only two rack spaces. That means the outlets are arranged horizontally, so most wall-wart power supplies will take up too much space and overlap adjacent outlets. That is easily solved by using short power-cord extensions designed for managing wall-wart issues. The Monsoon power cords are fairly flexible but resist rotational twisting when trying to fit plugs into the outlets. I found it much easier to switch off the power on the front panel, then plug the male end into the PowerQuest 707 first, then twist the IEC end to accommodate my DAC and amplifier. Plus, the molded IEC ends on the Monsoon cords are small, a boon with small, crowded back panels.
One ergonomic issue that is specific to my system is the short RCA ends of the Yosemite DIN phono cable. My AudioQuest Cougar phono cable has much longer ends, so there is no problem reaching the widely spaced (three inches) inputs on my Fosgate phono stage. The Yosemite's ends are only capable of one-inch spacing, so I connected it to my Lounge Audio Copla, with its closely spaced RCA inputs. This design choice wont be a problem for many phono stages, but those of you with Sutherland phono stages or other designs with similarly wide-spaced inputs will find the Yosemite DIN phono cable unusable.
