i've used them (along with KSL silver i/cs & p/cs) in both tube & SS systems.
tonal balance is pretty even with a slight emphasis in the mids. they hv a 65:35 ratio in terms of musical flow vs. structure. they're prob not as quiet, or hv as much resolution as some of the "modern" cables, but hv an overall balance & coherence that's hard to match. this is fm my personal experience & observation (everyone's room/system/music/perspective/etc. is unique, so YMMV).
