Best Amp for Type AA Klipschorns (1978)

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. 

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.

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

SET amps best with my Khorns, but since no tubes for you. I'd go with one of the sweeter toned First Watt amps. you don't need more power than what they offer. After much research, the First Watt was going to be my next try with SS amps. I had a Musical Fidelity M2si in for an audition at one time, pleasantly surprised by not feeling greatly deprived versus my two SET and one push pull tube amps.

I’ve heard the Atma-Spere a couple of times in the design stages over the past couple years. But that was at Atma-Sphere on non loaded horn speakers. That’s was why I was asking here if anyone had them with a Horn speaker. Thier impressions and such. Not many of the Atma-Sphere amps out there yet I am guessing. But that is on my list of possible amps. With the speakers Ralph had them on. They sounded impressive in all respects. 

I think you would be best to contact Ralph at Atma-Sphere and talk to him about his class D offering. 

Topping PA5 Class D amp - 50+ wpc - $349!

Thanks for the responses. I should have clarified Solid State.
mall good suggestions though. Want something that wife doesn’t have to worry about the tubes. She’d be lost if one went out and I wasn’t around. I am running Atma-Sphere Ma-1’s right now and absolutely love them. Alittle over kill for Khorns though… lol…. I don’t think I’ll be able to let those go. 

Depending on your volume level.  I'm running Speaker Lab corner horns with 2 watts in big room and they fill it fine.  

SET amps bring them alive.

No tubes? QS horn monos?
