Getting past discussions of how much power the Thiels would need...there's also the difference in sonics of the different amps.
Does anybody have experience hearing Pass XA series, Pass X series, and Ayre amps...preferably with Thiel speakers? That info is of more use to the OP than discussions as to how much power he needs...once he has an idea of the different lines' sonics, then it's a matter of choosing the appropriate power for his speakers.
I've heard Thiel speakers, and I've heard (and owned) Ayre amps. I suspect they'd work together reasonably well - but I wasn't a huge fan of the combo of Simaudio electronics with Thiel speakers - the combo was a bit edgy. Thiel speakers can sound a bit bright with electronics that are "modern" sounding - as such, I'd be looking for an amp that doesn't overdo the top end at the expense of the midrange. My guess is that, sonically, the Pass XA series would be better than the Pass X-series or the Ayre with Thiel speakers...so perhaps just moving up to a bigger XA-series amp is a good idea.
