Pass Labs XA60.5 experience?

Hello and thanks for your responses. I have since read every word I could find here from Teajay and Peter and the rest, great stuff guys.

Now if only I could find somewhere in this bloody universe the sensitivity rating of my speakers I might be able to make a final decision between the XA30.5, XA60.5s, or XA100.5s, the last being something I cannot afford but might be able to if I chilled a bit on the number of drinks I have in this new year.

Okay, please don't laugh at the slow kid but my beloved speakers are currently Miller and Kreisel's S-5000THXs. I love them.

Anyone happen to know the sensitivity of these speakers? Any recommendations on which Pass amp to match up?

Tiny room, Norah Jones SACD, Fleetwood Mac SACD, Dvorak multi-channel SACD, Mozart flute, Bach cello 3channel, Muddy Waters, Sam McClain, Miles, classic rock, rap and hip hop on occasion. Mostly mid-volume play, VERY loud play three Sundays per month. Speakers roughly 6' 2" from my nose. Three different sized Velodyne subs (incl. 18") cross-overed at different frequencies.

Also used in 7.1 blu-ray setup, all MK Sound speakers, all other channels driven by used Mark Levinsons. I want to upgrade and love love my 2ch.

Suggestions please?

Many thx

If helpful, my current pre is a Krell HTS 7.1 and my source is an Oppo 95.

All 2ch interconnects are balanced and I live in Southern California.. cheers.

The speakers are 93db @ 4ohm.

Mr. Magfan thanks much for your words. 30s would be so easy at $3500 used. The only other amp I'm considering short term is the fuel efficient Krell 302e on a splurge. I don't like that Dan and Brett have been minimalised, however, kinda pisses me off and I don't want to reward the new blood with a purchase. The Momentum isn't realistic for me in 2012. It seems a good time to be looking to purchaser an amp, choice-wise. Off subject, computer based high-end hires with the likes of HDTracks, LINN, 2L at 352.8k, Antelope Zodiac and Benchmark DACs, Sennheiser headphones, etc. is peaking my interest by the day. Just saying..
