Snake River Audio Signature Cables

Good luck finding Riggins, Idaho, without a good map. Located in the west-central edge of the state in the Pacific Northwest, Riggins, an hour north of McCall, is just over a ridge where the Snake River courses through Hells Canyon. Beautiful, rugged country, but as unlikely a spot for a cable company as I can imagine. Nonetheless, that’s where you’ll find Snake River Audio and its affable founder/designer Jonny Wilson. And business is good.

Snake River Audio (SRA) designs and manufactures analog and digital cables across most categories, including power cords and guitar and pedal cables. Its business model is factory direct. The company prides itself on customer communication and service. Playfully or alarmingly (depending on your comfort level with these reptiles), each Snake River model is named for a particularly lethal species—jararaca, mamushi, cottonmouth, adder, boomslang. But clearly, it’s all in good slithery fun. Certainly, the scaly, snakeskin look of these cables will put a smile on your face. The brightly multi-patterned jacketing of each model casts a fluoro-iridescent glow conjuring up memories of 80s-era spandex-wrapped, glam-rocker gods like Van Halen’s David Lee Roth and/or Aerosmith’s Steven Tyler. While most cables attempt to disappear into a room’s décor (and usually not very effectively), Snake River models go the other way, seeming to celebrate their eye-popping outrageousness.

This review marks Snake River Audio’s debut in TAS. For the first evaluation, its premium Signature Series cables interconnects (RCA and XLR), speaker wire, and power cords got the nod. (When the term “premium” is tossed around in the cable world thoughts of mid-five-figure pricing often comes horrifyingly to mind. Not so with Snake River where most Signature Series models are below two grand.) SRA describes Signature as its “hybrid” conductor formulation. Its primary signal conductor is strands of 99.999% pure silver and red copper augmented with 24k gold. Optionally, Snake River goes the extra mile by making available models in pure silver or 24kt gold over copper, as well. Signature is configured in an innovative “Eddie Twist” of multiple twisted pairs and conformed in such a way that it yields greater signal surface area and reduced eddy-current distortions. Connectors are top-notch WBT-0681Cu (spades) or WBT-0610Cu (banana) connectors and Neutrik for the XLR interconnects. The dielectric material is either polyvinyl chloride (PVC) or Teflon, depending upon the model of cable. The outer sheathing is a metallic and nylon mixture.

Since I was running active speakers and required a longer run of interconnects, I was provided with SRA’s Mamushi interconnects—magnetically shielded versions of Signature Series cables specifically designed to reject noise due to RFI/EMI (a particular hazard for long runs of cable). SRA cables are cryogenically treated and cured for 200 hours before shipping. 

Since SRA is a factory-direct operation, I found packaging and presentation to be superb, right down to the vacuum-sealed packets and the logo-inscribed carrying pouches. Jonny Wilson is particularly careful about service and customer relations. Once the order is submitted via the website, the customer receives regular emails informing him of the status of each cable as it moves through the various production and shipping processes. 

I listened to the Snake River cables in two reference systems: my small-room compact system based on ATC SCM20 passive speakers driven by an Aesthetix Mimas integrated, and my full-range ATC SCM50 active system, which is augmented with a pair of REL S/812 subs, a dCS Bartók, and a Pass Labs XP-12 preamp. Signature Series power cords connected the Aesthetix Mimas integrated amplifier and the Lumin S1 media player or Parasound JC 3+ phonostage.

Despite its outgoing appearance, Snake River’s sonic performance ran far more than skin deep. Signature slipped into my system with all the élan and character of a high-end traditionalist. Clean, confident, and texturally colorful, Signature Series wires delivered music in a warm, relaxed, almost sedate manner. They settled into my system like a soothing balm. These cables didn’t glamorize the sound or make themselves the centers of attention; nor did they attempt—through selective frequency swings—to cure all manner of sonic ills that can beset an audio system. They evinced excellent balance across the criteria that my ears tend to key on, namely micro-dynamics, harmonic sustain, and top-to-bottom extension. Treble response was particularly smooth and easy on the ears—even trumpet blasts, though appropriately brassy and aggressive, still retained the instrument’s signature glow and bloom. Bass response was equally up to the task, portrayed with tuneful pitch and dynamic brio in a manner that equaled some of the best cables I’ve experienced.

A fluid and smooth signature was the first thing to draw my attention. As I listened to Vaughn Williams’ playful and colorful The Wasps Overture (LSO, Previn, RCA), what impressed me most was the continuity and flow through this score’s many musical moods, as it accelerates and then turns contemplative. The feeling of an unbroken stream of harmonic energy emanating from the orchestral soundstage had me concluding that Signature Series was a classical music lover’s dream. 

Vocals, from chesty baritones to high-flying coloraturas, were expressive and detailed from the singer’s diaphragm up into the falsetto range. Sibilance possessed the requisite attack and transient electricity but rarely veered away from the naturalistic.

Dynamically, these cables could rock, unfazed by anything a typical, studio-pop recording could throw at them. They would, however, light up with musicality whenever a naturalistic, uncompressed recording came their way. Try Patricia Barber’s Higher twin-LP, 45rpm set on Impex for a master class in micro-dynamics, air, and harmonic sustain, coupled with the eerie sense of just being there in the studio with a group of world-class musicians.

Audiophiles often discuss the meaning of a lack of noise in a cable (or an entire system for that matter), citing the preternatural background silences that precede the opening note of a performance or the rests and lengthier pauses during a symphony. What these silences represent most to me is what isn’t being inflicted on the reproduced sound—what isn’t being transferred through the cables to produce distortions or colorations that can impair the music. Without a clean undistorted platform for the signal to spring from, everything that follows becomes, to a greater or lesser degree, colored or obscured. This is why timbre and textural expressiveness also rank high on my list of qualities that Signature conveyed—the darker sonorities of a viola versus the brighter bite of a violin or the warmer, gentler flugelhorn compared with the more aggressive trumpet. Signature Series effortlessly defined leading-edge information like a singer’s breath off a microphone, or the flick of a flat pick on a bluegrass mandolin, or a thumbnail riding the bottom strings of a flamenco guitar, or the grit of rosin on a cello bow. 

Imaging was stable and consistent from straight-on centerstage into the periphery of the soundspace. Signature Series cabling held images in place like, well, a boa constrictor (ok, enough with the snake jokes). Even the lowest level orchestral voices (harp, for example), gentle background harmonies, and choral work were essentially free of veiling or opacity. SRA’s ability to soundstage and elicit three-dimensional space from broad acoustic spaces like the Troy Savings Bank (Laurel Masse Feather & Bone) or the Myerson Auditorium (Rutter’s Requiem) was very good, indeed. 

Compared with pricier cables that have gotten my attention recently, like Audience frontRow or MIT Evo, Signature was only mildly subtractive, and then only in a couple of minor areas. For example, during Norah Jones’ “Nearness of You,” the piano soundboard wasn’t as broad and commanding as it is through the Audience frontRow. Vocal and low-level micro-dynamics could have been better graduated and the delicacy of the player’s touch on a piano keyboard reproduced in finer terms. And in a perfect world, I’d ask for a whiff more bloom and air on top. These are relatively minor issues that my ears tended to ignore after a minute or so of listening.

By any benchmark, Snake River Audio Signature cables represent an auspicious debut—the kind of coming-out party that would make anyone wonder what else might be cooking up in Riggins, Idaho. Combine that with competitive pricing, and these cables are well positioned for those seeking to make a major cable upgrade to their rigs. No snake oil here, folks, just the real thing. 

Well worth seeking out, Snake River Audio cables embody authentic high-end audio values, dollar value, and performance that just never gets old.

An Interview with John Bring of Cable Support Plate

Readers,

I want to welcome you to the first blog post on our newly rebuilt (from the ground up) website. In this space, we will feature special interest stories and first looks at the latest products by our writing staffs at TAS and hifi+. I will also periodically share some of the big picture items we are working on.

Which brings me to John Bring, the owner of Cable Support Plate. John and I met at an audio show back when those things were still happening. At the show I became fascinated by a cool new product he’d developed, and have since had the pleasure of trying it—with great success—in two different systems. That product is an easily installed outlet plate that helps properly lift up and support the heavy ac cables that many of us now use. Before sharing my observations, I got John on the phone and asked him a few basic questions about his business.

John, why audio and what’s your background?
Music has always been a part of my life, I started piano lessons at 3. That turned into playing piano and organ for community events. I also played several instruments in high school. When I went to college I continued to listen to music, but I did not like the sound of my stereo system, which eventually led to me building my first set of speakers.

 In 1985, I went to California to join Lockheed as an aerospace engineer specializing in avionics and navigation. As part of my job, I worked on software for flight systems and was a member of the team that embedded GPS in the navigation systems of aircraft. That was probably the very first application of GPS. When we weren’t occupied with avionics, the folks I worked with spent their time arguing about the sound of cables and interconnects and the merits of digital versus analog. As a result, I started going to high-end dealers and audio shows, and got deeper into the hobby.

Why this product, John?
There is an awful lot of ground movement in my state of California. After one shake, I noticed the plug on my system was not fitting tightly in the wall. This got me looking at power cords at audio trade shows, and invariably the heavy power cords were not seated tightly in the outlets. If the cord came loose, it could cause real damage. The engineer in me felt this needed a solution. Changing outlets requires UL certification, which is expensive, but wall plates can be easily installed by the consumer. I started experimenting. The first plate I tried was made out of wood. Then I got my son-in-law to draw up the plate in a CAD program. Next I approached a local 3D-printing shop. They printed the very first plate and several initial iterations. Once we got that done, I felt I had a useful and saleable product.

John, how do you design and test them?
I soon realized that the best way to make my plates was to purchase a 3D printer and produce them at home. This allows for strict quality control. Two printers now run full-time, night and day, and print various models. Testing of the plates is done with a friend who is an electrician. We built a “to-code” wall, looked around and found all the heavy power cords we could, and then tried the plate with various outlets. Our first test is to hang things on the support cup to make sure it can handle over ten pounds. Our second test is to simulate tripping on the cord and use that data to adjust the thickness of the cup. We have learned to use a combination of two 3D materials: one is stiff and one has a bit of flex. We then quietly began selling some plates to friends. All the feedback has been very positive—the plugs stay tight in the outlets.

One note about quality and time to complete orders. Plates take 14–26 hours to print, so orders may take a while to fulfill. I print at four times the typical resolution that most 3D DIYers print at, but that leads to a better finish and a stronger, more uniform structure.

 Because we delayed some of our launch, we also had an opportunity to use our printers to make headbands and heavy-duty facemasks for a local hospital during the COVID crisis.

So what’s my take?

I truly like this product because I use heavy-duty cables on my main audio system. These cables “drooping out” of regular outlets was a real issue for me (and I’m sure for many of you). The semi-circular support cups on John’s plate make a genuine difference. They simply work as advertised. Highest recommendation.

Italy (October 20, 2020)—European pro-audio manufacturer Outline has introduced its new L3000 multi-purpose amplifier.

The compact, DSP-equipped multi-channel amplifier can be configured to drive most loudspeaker configurations. Skipping the traditional 19” rackmount format, the amplifier is housed in a lightweight chassis using the same materials and polyurea external coating as Outline’s loudspeakers.

Outline Ships Stadia 28 Line Array System

The diminutive size is intended to help make it appropriate for audio installation projects where space is at a premium. L3000 allows 3,000 W of audio power to be tucked away out of sight, although Outline will also offer a dedicated rackmount kit to hold up to two L3000s in a standard enclosure.

Featuring two inputs and four outputs, the unit’s routing and operational parameters are configured using Armonía Plus, the amplifier’s management software, which also offers control of input / output levels and EQ, delay, polarity, crossover filters and limiter settings.
