Best RCA Digicable


My new DAC (LAIV Harmony ) inputs only RCA, no AES/EBU. I need a new RCA digicable to run from my streamer into the new DAC, used (preferable) or new. Any recommendations? I have been using Shunyata Sigma 1 digicable AES/EBU; cannot find used RCA version. Thx. Neal

I've been really happy with a bunch of Veritas Cables products I've picked up recently. They recently announced the addition of RCA, BNC, and AES digital cables to their lineup. I have not heard the RCA yet but imagine it is as good as the rest of their models (meaning excellent) and the value looks great for the price. 

I have tried a few RCA digital cables over the years including XLO, Discovery (2 models), and Audio Note Vx and Sogon, but my favorite by far is a Cardas Clear.  The Cardas has the most natural presentation with excellent detail and dynamics, and a smooth tonal balance.

Most consumer audio products adhere to established standards when designing digital interfaces and connections. Specifically, the impedance specifications for cables and connectors are 75 ohms for S/PDIF and 110 ohms for AES3 . Using cables or connectors that deviate from these standards can lead to impedance mismatches, resulting in signal reflections and increased jitter.

I mention this because several individuals have endorsed the Acoustic Zen MC2 cable, which is described as a true 110-ohm design . These users have reported no noticeable degradation in sound quality. However, their positive experiences may not necessarily apply to your specific setup. Therefore, I advise adhering to standard specifications to minimize potential issues.

Additionally, it's worth noting that the MC2 cable is constructed from pure silver. Silver conductors are known to produce a brighter sound in the upper registers, which can give the impression of enhanced detail and treble or upper midrange performance. Whether a silver cable complements the Harmony DAC depends on the overall system synergy.

Lastly, pay attention to the capacitance rating of the cable. An S/PDIF cable with higher-than-normal capacitance can function like a low-pass filter, attenuating high-frequency signals and rolling off the treble. This phenomenon has been empirically observed and reported by end users on multiple occasions.  Practically, you want to avoid capacitance rating over 200 pF/m (or 60 pF/ft) or longer run to avoid any audible degradation in highs.

Neotech NEVD-2001 Pure Silver digicable. It's not even expensive so you don't need to look for used..though I've never seen this model on the used market. I would describe it as "liquid"...how you like that lol. 

The Neotech certainly isn't in the price range of a Sigma so many people will probably roll their eyes at the $300 price tag. Actually I think they are even cheaper these days but I feel it's one of those cables that one should try if they can't afford the heavy hitters. The connectors on it are worth the whole cable price in my opinion.
