Boomslang Digital SPDIF Cable
The Boomslang Digital SPDIF cable is where our digital journey began. For more than a decade, it has been trusted in serious systems and has earned its place as a reference-level design.
Unlike conventional coaxial cables, Boomslang is built entirely from pure silver in a controlled parallel-linear geometry. The goal was simple: eliminate unnecessary dielectric interaction, preserve timing integrity, and allow the data stream to pass with minimal electrical distortion.
Pure silver favors speed, articulation, and clean edge definition. In digital transmission, that translates into stable timing, strong image focus, and a presentation that feels wide open and dimensional rather than compressed or mechanical.
Open. Fast. Resolute.
Parallel-Linear Geometry
Boomslang does not use a traditional coaxial design.
Instead, it employs a controlled parallel-linear architecture that maintains impedance consistency while reducing the dielectric and structural compromises common in standard coax builds.
This geometry was developed to preserve edge integrity and minimize reflection artifacts without relying on typical coaxial layering. The result is stable transmission behavior with exceptional timing control.
Why 1.37 Meters Matters
For more than a decade I have maintained that 1.37 meters is the minimum effective length for SPDIF and AES digital cables. This is physics, not marketing.
At shorter lengths, reflections caused by real-world impedance mismatch can return during the receiver’s vulnerable timing window and raise jitter. By setting a minimum length of 1.37 meters, the first reflection is pushed outside that critical window in most real systems.

Built by Hand, One at a Time
At Snake River Audio, nothing is mass-produced. Every Snake River Audio cable is custom-built from the bare wire, raw materials per order. No shortcuts. No outsourcing. Just real craftsmanship, by me and my team, one cable at a time.

Lead Time & Curing
Once your order is in, it goes into the build queue. Refer to the Build Queue indicator on our website for the current turnaround time. Once its turn comes up, we’ll hand-craft your cable and, unless you opt out, run it through a 200-hour curing process before shipping. That means it’s almost fully cured, or "burned in" and ready to perform the moment it hits your system. A little bit of settling time is always suggested, but for the most part, they're ready to go!
Build queue is typically about 8–10 business days, and including curing, most orders ship in about three weeks. But please refer to the Build Queue Indicator for up-to-date reference.
You’ll get automatic email updates from the website throughout the process, including tracking once it ships. If you don't see them, check your "spam" folder. Be sure to mark these emails as "not spam" to ensure future updates.
30-Day Trial. In Your System, On Your Terms
I get it, you need (and should) hear it in your room, not some showroom or hotel suite at an audio show. That’s why we offer a 30-day risk-free trial. If you're not blown away, return the cable in like-new condition and get a full refund, (minus shipping and processing fees). Read more details about our return policy here.
Less than 3% of our cables are ever returned. In fact, over 40% of our customers come back for more. That says more than I ever could.
Trade-In Program
Got a Snake River Audio cable you want to upgrade from? Let’s make it easy.
We can accept genuine Snake River Audio cables for trade-in. Just contact us first at SnakeRiverAudio@gmail.com. Once received, we’ll evaluate it based on condition, age, and type, and assign a fair trade-in value, usually 50–75% of original retail.
We list used cables at near break-even, so your trade-in value will reflect actual resale (minus payment and shipping fees.)
I am currently working on a process/partnership to be able to accept non-SRA cables as trade-ins. If you have cables that you don't need any more, even other brands, email and let me know what you've got. I'll need make, model, brand, length, terminations, age (if known), and a couple of pictures to be able to give you a close estimated trade-in value.
Please note: During sale periods, trade-ins are discretionary and handled case-by-case.
