Best RCA Digicable

For the record, the Harmony does not "input only RCA".  It features i2s, Optical, and USB inputs in addition to Coax.  i2s is preferred if your streamer allows.

@soix Acoustic Zen MC2. Read the reviews.  I own it.

On Amazon, look for “Amazon’s Best” and you’ll find all lengths of RCA cable. 

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.
