Wow! Thanks to all of you for the quick, detailed and informative responses! Let me try to answer collectively: you are probably right that because of my music and environment I will not need th sheet grunt of the X-600's. I mean, if I decide to hold a week-long salute to organ music well ... yea, maybe I might need horsepower. The JC-1s with 400WPC have had no issues whatsoever powering the Prodigys and the SoundLabs. So the X350.5 should not either.
The only reason that I was considering the X-600's was because of the dreaded crosstalk issue: there's something appealing and logical about mono amps. On the negative side, though, one less amp means once less box that makes the stereo room look like a mad scientist's laboratory.
The advice to audition the amps is reasonable but, regrettably, I don't want to take advantage of my local dealer. I can't afford the new price tags of either component. I was just attracted by the fact that the X-600's and the X-350.5 are avaiable at roughly the same price of around $6,000.
But there is one thing that rubbed me the wrong way about the responses to my question: Jameswei is on record as stating "First, if you're happy with the JC-1s, I'd stay with them." What the hell????? What sort of audio talk is this? Are we sure that Jameswei is really one of us? Can someone do a background check on him? I would not be surprise if we discover that he is a paid lacky of the International Global Book Readers Consortium. That sort of reasonable talk has NO PLACE on Audiogon.
As a refreshing comparison, Teajay rightfully advised me to forgo that checkup to find out why I'm spitting blood and whether the numbness in my arm is anything serious. "Everthing else can wait!" he says. Now THAT'S sound (get it ... "sound"?) advice!
