I use the TS premium IC's for my DAC to preamp and preamp to Mono Extreme connections and I use the TS Premium speaker cable for the Mono to Lorelei connection. I went through a bunch - at least 15 - different ICs until I ran across a pair of used TS cables and gave them a shot. I have not considered any other cable since. As you said, it was immediate, dramatic and absolutely wonderful! I don't know if it's the synergy thing or exactly what but these are excellent cables that don't get their due.
