Steve Nugent’s (Empirical Audio) new reference S/PDIF cable is quite good. Equals all I’ve previously used, including a few at 4x its $495 price.
Suggestions on upgrading from a Kimber Kable D-60 digital coax.
The D-60 runs between an Aurender N100C (the latest N100 with digital coax) and a Schiit Audio Gumby. I am looking for a cable with warmth and detail. My favorite IC's are Purist Audio (between the Gumby and my Rogue Cronus Magnum and between my phone pre and the amp). Price range is $400-$500.
