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

I've owned the Xa-25 for 3 years now and love it still. 
Super quick, quiet, micro detail (class A to 50 W) and as dynamic as all get-out.  Cable swaps are easily heard - nothing in the way.  Plenty of power with 90 dB, 6 Ohm speakers.  I'll bet Tektons would blow the roof off!

Underwood HiFi is supposed to be releasing their Voyager GaN amp around now. They might still be offering a trade policy. I would definitely pursue it

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!

I have a pass labs xa25. I cannot compare it to the amp you are considering. I have not heard it.  Though the xa25 does not get too hot at all. 
It shines in midrange, it’s warm, very quiet, and forgiving with poorly mastered cds. I can only advise regarding the xa25 that you do not utilize  oversized spades on the amp side. They only partially fit. Also a speaker cable of silver and copper 50/50 reveals more detail. All copper and it might sound a bit flat. I’m running them with special 40s in a very small living room. Works well for me. 
Best luck!
