Need highly transparent detailed amp---how does Pass XA25 compare to Gamut D100/D200 MKIII

atmosphere---the 45w my JAS Array 2.1 puts out is about the minimum I could use and get the sound levels I want.  I've had 2 of these amps and love the liquid midrange and the palpable 3 dimensional images and everything else I've heard has sounded veiled in comparison.  A couple gainclones have had an acceptable sound so I think I can get (mostly) to where I want to go with solid state.  And as mentioned, I don't want to spend the bucks on more tubes.  It's close to $1000 to get the tubes I want/had for this amp.  And my experiences with class D are the early PS Audio and Wyred4Sound amps and neither moved me at all.  I hear that class D has come a long way but both amps I mentioned have many excellent reviews indicating they may be the sound I'm looking for.  Thanks.

atmosphere-----thanks for all the insight.  Truly useful info here is a rare commodity.  And funny you should mention the H/K Citation II as I had a pair of a modern rethinking of that classic design in monoblock form, the VAS Citation II's.  These really are quite nice and, although of the same power rating, were able to drive to moderate levels a pair of BG Corp 520 loudspeakers that the SET JAS amplifier could barely rouse at all.  On speakers more suited to them though, the JAS was quite a bit more revealing of the subtle inner details that make music engaging to me.  With Shuguang Treasure 6CA7's, the VAS amps were luscious and quite detailed and always a pleasure to listen through but the JAS just had more insight.  I like tubes in my source (presently a Raysonic 228 and a Modwright Oppo BDP 83SE with the tubed outboard power supply) but otherwise would like to get back to a solid state amp for full time duty.  Thank you very much for the wisdom

tweak1   what is a Voyager GaN amp?  Years ago I swallowed the cool aid to quickly and traded in a JAS Array 2.1 SET for a new Wyred4Sound ST-500 there at Underwood.  I read the review of how great Class D was and it was a huge disappointment.  The extra power was nice (and bass) but everything else was a BIG step down in sonics.  Not saying the Voyager will but, just reflecting. 


And don't have Tektons yet.  My main speakers are DIY/customs of a similar design to Legacy Focus but using Eton drivers.  It's also quite sensitive but requires bi-amping. 


I've been looking for Valvet on the used market on Hifishark but they seldom come up so... will continue to consider although there are a couple Gamuts available presently so might jump on one before it's too late.  Thanks all for the input!

That's certainly an option and in the same used price range.  I just hate paying practically list price for a used item.  With these and the Tektons, it makes more sense to buy new.  Thanks for the recommendation.  I'll certainly keep it in mind.

kairosman ---funny you should mention the Kinki integrated.  I looked into it (and still consider it for a secondary system).  I don't like active preamps though (nor passive I guess---source direct only for me).   I've been considering trading in toward the one listed on TMR.  And I think you're right about no one here having compared the two directly.  Sounds like the Gamuts might be more what I'm looking for though the Pass reviews are all so glowing.  


And at $15000, the Simaudio is about 80% more than I can afford.  I won't even look up the reviews so as not to torture myself.  


Thanks to all who contributed

gato?  I haven't heard that one.  I'll look into it.  Thank you
