Ayre V-Kxe and Thiel 2.4s

Charles1dad, we don't know of Steve's great sonic results, only of his opinion of such. Thiel recommends more power, Pass recommends more power, and there hasn't been anything but an anecdotal reason to suggest otherwise. The measurements provided by Steve don't seem to suggest that the c-j or something very similar, would be as good, never mind better than what the OP has already tried. I would think that the point OP started this thread was to expedite the process of selecting the appropriate amp for his needs. With that in mind, I think it fair to point out that the c-j or something very similar, for the reasons I've already posted, is not as likely to satisfy the OP to that end as much as some other alternatives.

Unsound I certainly accept your apology, no problems.

Cal I`m glad you`re getting more out of your current Pass amp.Sometimes more power is the answer, but often I find it`s not the core problem. It`s usally higher 'quality' that`s needed.

Charles1dad, thank you.

Cal3713, I was just responding to your thoughts of adding an independent 20 amp line for your amp.

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.
