Well, I did it. My order is in for the Ars Sonum. It will be interesting to A/B against the Placette Active (which I prefered for the CAT SL1)/CAT JL2 combo. I don't believe for one second that the Ars Sonum is the equal of the CAT Amp, which IMHO is one of the great amps on the market and perhaps the very best P/P amp. The CAT will sing in ANY system, with almost any speaker. In that sense the CAT is clearly better, because it has wider, more universal application. That being said, I'm buying into the idea that an amp that is highly optimized to perform very well with a specifc speaker in mind is very promising - while I suspect (know?) the CAT is the greater amp overall, the Ars Sonum just might be able to provide just what the Merlins need to sound their best. If after A/B the two, the Ars Sonum is close to my current $20,000 worth of separates, I will be selling my Placette and CAT on Audiogon, pursuing a simpler path to musical enjoyment. If it can't beat them IMO, I will tell you that to. I suspect it will be several months before I get the unit for evaluation, by which time this thread may indeed have a expired. But then I'll start a new thread in the Pre/Amp category where that discussion should probably take place. Thanks.
