Ayre V-Kxe and Thiel 2.4s

Countingbackwards, the XA30.5's the OP was using is a pretty modern design. Moving up to a more powerful XA.5 would probably be ideal, but there are budget considerations.

Yeah, I wish I could go higher in the XA line. The 60.5s are kind of in the zone, although even getting the funds for that purchase would require living with the 30.5 for a couple more years. Although Renohifi suggested that that could be a solution, Pass themselves recommended the XA100.5, followed by the 350.5, and then the 250.5 as the best matches for the Thiels.

Any of the newer Coda amps would do a fine job with this speaker. All double down to 4 ohms and most are even 1 ohm stable. Most might recall a couple were specifically designed to drive low impedance panels and Coda OEM for Innersound/Sanders sound. Thats were I'd look.
Good Luck

Interesting thread. Further thoughts are that, of the three much higher powered integrateds I owned for a time in this system, the CJ CA200 was the most enjoyable. What I missed though was the upper bass warmth of the CAV50; this is my second one, I too "second, third and fourth guessed" myself and finally returned to this model. Certainly that amp could drive the Thiels to much higher levels and not venture into tube glare territory. But i can get this system up to 95 dB with most music before glare sets in and that is more than I normally listen at for extended periods (I mean, how high do you guys expect to be able to go?). Fortunately I was able to find another on the 'gon and once this was back in the system, all sounded "just right" once again. I used to be very critical of the ear vs. technical issue, reading the literature on this, the Absolute Sound vs. Sterophile battles, etc., and, for a period of ten years or so, was convinced that measured specs were perfectly predictive of sonic performance. I have now at least partially moved over to the other camp in that there are component combinations that empirically defy technical predictability. Believe me, my expectations used to be more closely aligned to most of the sentiment expressed above with regard to the need to high current and Thiels.

I also have CS6s and when I was trading up from Bryston 7B monoblocks ten years ago, I first purchased a Krell 300cx amp; it was OK but I decided to try the 400cx the next day, so I took back the 300cx and traded up (full credit within 24 hours, blah blah) . The rssults were clearly heard. The more powerful Krell made a distinct improvement in dynamic swing and width and depth of staging. Bass was also improved. So there was my conclusion that high current amps are de riguer with Thiels. Until the CAV50 appeared, that is.

I really do wish you guys could hear this set up, at the very least it would make for some interesting conversation. If I hadn't "validated' it with others I trust, I wouldn't be so promotional about this. Remember it's that first watt or two that we most often listen to to drive our speakers to 80-90 dB levels in he listening position, and I can only conclude that in this case it is the quality of those first couple of watts that make the difference. I'm not using any NOS tubes either, but only low noise selected versions of JJs from tube depot.

I know this is somewhat arbitrary, but I think a system with high end aspirations should be capable of 100 dB peaks.
