Agree with Thorman about checking out realitycables.com, with the money back trial method, for excellent performance without sticker shock. I found the recommended OFC RCA connector option to be a significant upgrade to the terrific IC.
Sold also through Audiogon dealer,Clearsound, who sells your DK Design integrated amp. You could get some help from that dealer by phone, if you prefer.
Using this brand's speaker wire and IC together is synergistic, although in another system I did retain other companies wiring products where too many sources to replace every IC.
