Just got a pair last week per Bobby's recommendation. I also have Merlins- TSMmmis with regular RCs. I was using Greg Straley's Reality cables before, which were pretty good. First impression is that the Cardas SE 9s are better, but they've only got a few hours of burn-in time on them so far, so too early to give you a true impression. My amp is a vintage Fisher 500c, a 35 watt tube receiver.
I also have not heard much feedback from other a'goners or others on this cable. Would love to hear other's impressions as well. And I'll be glad to share my own thoughts too, after more burn in.
