@mitch2 - I'm very happy with Steve's Helix design. I have used silver from Chris in the past, but OCC solid copper (partsconnexion) with teflon and the Helix wrap has become my reference. About to try a triple C (Acoustic Revive) wire to see if I can tell a difference.
Only build XLRs, no RCAs. Strictly from my streamer/dac to amp. Although, really intrigued with all in ones that make cabling (which I loved to build) a moot point...
