pass labs xa30 to valve amplifier.

Well, either way, you will own some very fine equipment, with what you have, or what you are considering; everything mentioned on this thread could be the basis of an excellent system, so I don't think you going to wrong with the options you are considering, once you get the preamp or no preamp issue resolved.

Well, I wish you lived near Florida. I own the Cary SLI-80 F1 and have been kicking around the idea to try an XA30.5

I guess the grass is always greener on the other side. Anyway good luck, I hear OTL tubes sound great, but my speakers are 4 Ohm 92 DB and 7 drivers (Montana XP) and was thinking that a good solid state amp could control them better.

Your speaker seems well suited for what SS can provide - current and damping- good thing air-condition is readily available in Florida - though, I would say the M60s threw off more heat than the XA30.5. There must be a Agoner XA30.5 owner somewhere in Florida.

XA30.5 is excellent. As mentioned above the Atmasphere might not be what you are looking for. They are not bloomy. Also, in my case a fine tube preamp will do the trick. Pass can sound more valvy than most tube amps. To get more bloom you might sacrifice detail. Be careful as you might be going sideways at best.

This is an excellent thread and the tubed vs solid state discussion in some ways has been replaced with the amp/preamp characteristics that you most value. As many posters mentioned, you can get different sounds depending on the tubed/solid state components you choose. The speaker you have plays a big part in determining what the best match might be. Poster Koestner talked about having 4 ohm, 92 sensitivity speakers and thinking about a solid state amp. When you have a lot of drivers and are 4ohm, I have found that you need a good amount of juice to get the speakers to really light up. There are powerful ss and tube amps. I have had three of the amps in the Pass XA series and have written about my experiences with them. The XA30.5 just did not have enough juice to push my speakers and though a wonderful amp, in my situation, I needed more power. Keep in mind that with any decent speaker, you will notice changes when you play with the amp choice, the preamp choice(or lack of), as well as the source that you use. The will all effect the sound.
