Flagship digital cable delivers master tape-like realism, enabling digital sources to rival the musicality and three-dimensionality of your finest vinyl.

I own Bliss Hifi, a high-end audio boutique and this Synergistic Research 1M USB Cable is my personal dealer demo. It is 1.5 years old and is in very good cosmetic condition and perfect working order.
The SRX USB cable is one of Synergistic Research Flagship offerings and, along with the SRX XL USB cable, is by far the best USB cable I have ever heard. It has absolutely destroyed its competition through its combination of natural presentation, coherence, and realism. I have historically not been a fan of USB cables for my digital chains due to the 5V rail that, despite isolation, can still induce noise into the signal. The SRX USB completely eliminates this, and I have found better results in using it even over other SRX digital cables.
SR no longer ships dealer demo cables in factory boxes, but I will be sure to pack and ship it securely. If you are interested in a factory box, I can certainly inquire, and it will likely cost $25 to get one dropshipped to you from the factory.
As a long-time SR product user and now experienced dealer, I have extensive experience about the entire product ecosystem and possible upgrade paths. I also have extensive experience with digital audio products, from DACs, streamers, clocks, etc, and I can help explain the benefits of SPDIF vs USB, etc. I’d be happy to talk about pairing with your equipment or other SR accessories if you have interest.
Check my stellar feedback across online marketplaces and Google reviews and buy with confidence. This listing includes free insured shipping across the CONUS. I prefer fee-free payments, which include ACH bank payments, PayPal F&F, Venmo Gift, cashier’s check, and personal check (has to clear prior to shipping), but I can accept credit card payments through my QuickBooks invoicing system.
Happy to answer any questions. Thanks for your consideration.
More about this cable:
The Synergistic Research SRX USB shares the same hallmarks as the rest of the SRX lineup—an ultra-low noise floor with inner detail, dynamics, and holographic realism to rival the best analog playback while setting a new digital benchmark. Hand-built in Synergistic Research’s California factory, the cable employs an exploded geometry comprising two 3rd Generation Silver Matrix conductors and four Silver Air Strings, each handmade from 99.9999% pure silver in an air dielectric with a UEF grid running the cable’s length to lower the noise floor and expand the sound field. Each hand-made geometry and ground plane runs through carbon fiber discs to maintain separation between conductors for lower capacitance and cross-talk. The cable features UEF Matrix Shielding with Graphene and undergoes SRX Long Duration Multi-Frequency High Voltage Conditioning—treating all connections and cabling with 1,000,000 volts of electricity at specific frequencies and pulse modulations to create canals in the conductor material at the molecular level that allow electrons to flow more freely, providing enhanced clarity, musicality, and detail without fatigue.
Voicing to your system is accomplished through supplied Gold and Master carbon fiber UEF tuning modules that work entirely outside the signal path, handcrafted from carbon fiber and aircraft aluminum with the Gold option plated in 24k gold. Gold delivers a warmer and more liquid balance while Master provides increased air and focus—the optimal choice depends entirely on your system, discovered by experimenting after allowing the cable to settle for 48-72 hours. For an even lower noise floor, the SRX USB’s Ground Plane can connect directly to an Active SR Ground Block, bypassing component power supplies. Anyone experienced with master tapes understands the significant difference between the best digital and tape, with tape possessing detail, musicality, dynamics, and three-dimensionality not found in other formats—SRX USB takes your state-of-the-art DAC close to your best reel-to-reel tapes while enabling CDs, SACDs, and digital files to compete with and surpass all but your finest vinyl recordings. Priced at $5,995 for the standard 1-meter length, the SRX USB represents the pinnacle of Synergistic Research’s 30-year development in digital cable technology.
