A year ago I auditioned $6K worth of Venom-X cables. The audible difference/improvement was like buying a new piece of electronic gear. Needless to say I kept all of those cables. At the time I was using Rogue M180s, Rogue RP-7, Focal Kanta No.2s, Yamaha CD-S1000, NAD C-658, Thorens TD-1601, Hegel V-10, Ortofon Cadenza Blue. A few months back I sold off the Rogue and Focals gear and am now using a Pass Labs XA25, a Rogue RH-5 preamp, and Wharfdale Linton speakers. For fun I went back to my old AQ Water cables. The Venom-X still sound much better in the new system. To my ears they are some outstanding cables and across at least 2 platforms. I have other amps I swap in and out and I don't seem to realize any negative change in sound quality I can tie directly to the cables.
Your mileage may vary.
