Aegir upgrade to Pass...maybe


I have had a Schiit Aegir for about a year now. I drive quite efficient Crites loudspeakers. I am thinking of getting an amp with a little more power. The following are my leanings.
Pass LabsXA25
Pass Labs XA30.8
Benchmark AHB2
I think the XA25 will be a good choice but wondered about the XA30.8. Somewhere I read that the XA25 actually sounds better than the 30.8. The 30.8 is monstrous at 94 lbs.

Also, I see high ratings for Benchmark. Does this sound like Class A, A/B or D? The reviews say really detailed and accurate but it is definitely different than the Schiit or Pass Amps. Plenty of power for my system for sure.

Thanks for your opinions and suggestions in advance.

Note that Dennis Had sells new amps on eBay only (except some "Dragon Inspire" stuff over at Moon Audio), and as with any lower powered single ended amp you should use efficient speakers. My "Firebottle HO" is the best sounding amp I've heard in many decades of this stuff.
I owned 2 Aegirs as the first one was faulty and was replaced. The second one had the same issue (although not as pronounced as the first) of shutting itself off when pushed a little (and not so much...my 99db speakers get loud fast with little wattage). When I replaced the Aegir with my Dennis Had tube amp all was well again, and the Had amp sounds so much better I sent the Aegir back. I've heard the XA25 in a friend's system but not in mine, and it sounded amazingly good...I might try one some day but my little single ended tube amp is so good there's simply no hurry.
I noticed somebody else had the "shut off" issue with the Aegir which alleviated my worries that it was maybe my subs connected to the speaker outputs being an issue, although it's never been an issue with other amps. The subs (RELs) load very high impedance (100,000 ohms or maybe 50,000 as I use two) onto the amp which should have virtually zero effect on the thing. An amp that kicks in a protection circuit with 99db speakers is useless to me as it would seem to be putting out maybe 10 watts when playing very loud (louder than I need or seem to ever use), and would appear to have overprotective protection. I had high hopes for the Aegir, but now simply assume the Pass XA25 is down the road...maybe...
