My system is modest but very sensitive to any changes. However, once I had some fun with comparing Wywires Diamond, that's their top of the line $2700 RCA cables, and older Gabriel Gold Infusion RCAs. I was using my trusted Nakamichi 682ZX deck as a source and VAC Avatar integrated amp. Damn, they were so close, but at the third go I did hear slight differences, not better/worse but differences. They both sounded great and I use then both. In higher resolution system the differences might be more pronounced, I don't, know. Wywires is a little more balanced and Gabriel Gold more engaging. I bought them both used, Diamond for $1150 and Gold for $200. For most recordings, especially acoustic music, I actually prefer Gabriel Gold a little.
