Class A amplifier choice, need suggestions


What is your favorite class A amp and why? There are many here on Audiogon... Levinson, Krell, Pass Labs, Plinius and an occaisional Accuphase A50V. I am driving Proac Response 3.8s (88dB efficiency). I recently auditioned a Pass Aleph 5 and was stunned by the presentation at only 60wpc.

Your input is much appreciated!

Hello:

I am using Jadis JA-80 with Proac 2.5 , it is very warm, musical and delicate sound. I am only listen to classical music, I think Proac has perfect match with class A tube amp. It is smooth sound in high and very warm in Midrange.
U can try Aleph 0 monoblock, it should be good choice.

Good luck
I run 87db speakers @ 8ohms in a room 16x26x8 and rarely measure 90db @ 1m. The amp sounds exceptionally well in my system and will fill the room with enough volume to hear it outside (4 sound room walls are insulated with r12 with r20 behind that on three walls and cement foundation walls on three walls and the ceiling is r12 with a sound barrier utilized between it and the subfloor above.

I couldn't justify the ML 33H price and am satisfied that the 5 is a greater value and a near equal performer!
I agree with JamesWei. The Pass X600 is one awesome amp. Unbelieveable with Revel Salons.
Need solid Class A advice contact Jon Soderberg at http://www.rsvlonline.net/vintageamp/ Jon worked with Nelson Pass at Threshold for many years. Bought a Forte Model 4a Class A amp from him and could not be happier. He may have something you can use,or get some really first hand advice from him. He did have a killer Threshold SA 3 Class A amp for sale a few weeks ago.
For solid state amps you really can't go wrong with the Pass Aleph series. I have Aleph 1.2 monoblocks and think they are fantastic. I have a friend with Pro-Ac speakers and he drives them with tubes and they sound great even though the amp is class A/B push-pull. You may not want to limit yourself to pure class A amplification.
