I'm an old-timer in this business and so "cabled-up" way back in the mid-eighties, buying used Monster M1000 (their top-line) interconnects in many lengths. Liked them very much, although I only compared them to about four other brands. So over time I have grown two complete Thiel systems strictly with these cables, other than for speakers where I use WaterCables (the Monster speaker cables seriously degraded the sound of my Thiel 3.5's.)
These Monster's calling cards were audiophile cables long before the name showed up in Best Buy. The M100's new in the '80's were around $200 for a one-meter pair (most of mine were bought used at about $100 a pair.) Their calling card was three woven layers around increasingly larger dialectrics, and Monster says they were "phase coherent". Don't know about that, but they do have depth and width of soundstage, as well as naturalness and coherence on individual instruments, and every improvement I've made in components has been audible, so they don't seem to be masking anything.
Anybody else had experience pro or con with these? Tom, I take it from your comments that you haven't. Did Jim or Thiel corp ever try them?
