I own Bliss Hifi, a high-end audio boutique and this Synergistic Research 1M SRX Digital Coax Cable is my personal dealer demo. It is 1 year old and is in very good cosmetic condition and perfect working order.

The SRX Coax cable is one of Synergistic Research Flagship offerings, and one of the best cables you can get on the market today.

SR does not ship 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 Digital Interconnect represents the company’s all-out assault on digital cable performance, sharing 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. Hand-built over eight hours in Synergistic Research’s California factory, the cable employs an exploded geometry comprising one 3rd Generation Silver Matrix conductor, one 3rd Generation Silver Matrix High Current conductor, and two Silver Air Strings per RCA (four per XLR). Each Silver Air String is handcrafted from 99.9999% pure monocrystalline silver in an air dielectric with a UEF grid running the cable’s length to lower the noise floor and expand the sound field. The 3rd Generation Silver Matrix conductors feature monocrystal construction with copper core, solid PTFE dielectric, silver braid shielding, and Quantum Tunneled Ground Plane Technology, with listening tests performed for signal direction before build. All connections use WBT 4% silver solder across 12 point-to-point hand-soldered connections per RCA.

SRX UEF Matrix Shielding applies two different UEF coatings with Graphene to the UEF Cell, connectors, cabling, and ground, significantly reducing the noise floor while providing a dampening effect that allows a purer signal to transfer with less grain and more warmth and detail. The cable undergoes SRX Long Duration Quantum Tunneling, 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—maximizing low-level information retrieval and realism. Voicing to your system is accomplished through supplied Gold and Master carbon fiber tuning modules handcrafted from carbon fiber and aircraft aluminum, with Gold delivering warmer and more liquid sound while Master provides increased air and focus. The shields can be grounded directly to earth via an optional SR Ground Block, bypassing component power supplies for an even lower system noise floor. Anyone experienced with master tapes understands that tape possesses detail, musicality, dynamics, and three-dimensionality not found in other formats—SRX Digital 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.
