Best Amp for Type AA Klipschorns (1978)

Have an Atma-Sphere MP-3 pre, BelCanto Streamer/Dac. Running Roon. I have been toying with the idea of replacing my amp. Only to make things more user friendly for my wife long term. I’ve toyed with the idea of Class D and then come back to Pass Labs. Been researching First Watt and the XA-25. Seems people prefer the XA-25 over the 30.8’s.  Anyone here have Atma-Sphere Class D? If not class D what do you guys think about the Pass Labs I am looking at for these speakers?  Any comments are appreciated. Thanks in advanced.

Nice…. Yeah I’ve been thinking First Watt. I’ll have to do more research. Seems the F7 maybe a nice one to try.

With Khorns quality of watts all important, you could probably run them just fine with a 2a3, perhaps even 45 tube amps. The issue with all the lower power tube amps is you need nice power supply to cope with pretty severe impedance curve that slides down to around 3 ohm at 100hz.

 

First Watt amps say it all with their brand name, the first watt is the most important, Khorns can take advantage of that. I can't recall the First Watt models I was specifically looking at but I think the F7 and J2 were both on my list.

Yeah my Ma-1’s are 140 watt tube power. Drives them just fine. Lol… and sounds even better. I did install the gain plug as well. Thanks for the input on the F7. Seems quite a few people prefer that amp.
