Power for Thiel 7.2

Thanks for the reply. Guess problem is there's usually not a prompt and I have left it at that, it's been two months afterall!
The dealer said no, and rep said no, and a few goners said no too - and I went X250.5. Couldnt afford an x350.5.
In a nutshell, I am baffled.
Have had it for almost 5 weeks now.
Mated to a ML26 preamp and Esoteric/Teac DV50s. ML 26 doesn't have XLR input and this seems to be the achilles heel. In short, at the moment, system sounds bright at times.

Compared with my old ML 27 100 watter, I honestly think the X250.5 doesn't mate well with the preamp. The improvement from the X250.5 is manifold - depth, transparency, detail, soundstage, air, holographic presentation. Dynamics is improved the nth degree.

But it may be too revealing and bright - could it be the DV50s? The warmth with the ML27 is now gone completely.

In any case, I had demo x350.5/JR synergy IIi/Metronome CD3/Avalon speakers - it was a beautiful combination. That's why I bought the X250.5.

Mr. Pass has been exceptionally helpful in my little journey and I cannot wait to pair up my Pass with the JR preamp. I very much suspect that as the signal is convereted from comac/single ended input to XLR output in the ML26 it is degraded, essentially asking the preamp to do the amp's job...

Ain't gonna work...

Hopeful, and appreciative of all well intentioned advice, and will certainly post my little review once I get everything on board...

Why don't you try some MIT cabling preferably Oracle. It has nice tonall balance with a lot of detail but never harsh or fatiguing. May be just what you miss.

BTW told you to get SIM AUDIO

I heard them sound great with a bridged pair of BAT VK60s.

I have used both the Thiels and Watt/Puppies (my current) speakers. They are very different but share one common characteristic: they are highly detailed, sometimes sounding analytical or a little bright to the point of hardness, especially with less than perfect source.

I found that the MIT CVT cables, while not ideal for other speakers, match the Thiels and W/P very well because they tend to soften the top end just a tad.

Likewise, I found that a pair of BAT VK-60--the newer SE-75 should be even better--can drive these speakers to great satisfaction because of good match in strengths and weaknesses. The midrange is glorious, the top end detailed and smooth. Only the bottom end could be a little tighter and deeper, but I use a subwoofer so that's not a big problem. The solid-state amps I've tried delivered better bass but none could properly handle the speakers' top end. Of course, I haven't tried everything.

A Bryston 14BSST works very well with mine. I have heard them at Thiel with the Krell 600, and they sound nice. Be careful on cables, some with network boxes that claim to enhance imagery, actually do so by boosting the top end. If you lower the volume to compensate for the boosted top end, you might think you have lack of bass.
