Class A amplifier choice, need suggestions

My favorite is the Pass X600 monoblock. It operates in class A up to 100 watts continuous (200 watts peak), then shifts into class AB mode. While it doesn't go up to the X1000's 1000 watt max, its 600 watts of rated continuous power is more than enough for most applications, and it doesn't have the X1000's power connection idiosyncracies. It sounds terrific in the midrange, pretty good in the high end, and OK if not super in the bass.

Hello,

I currently own an PS Audio HCA-2, which is one of the cheapest class A rated amps (by Stereophile) in the world. The sound is awesome... very fast and tight bass, transparent and grainless trebles, female voice sounds exceptionally good. I had it run for 5 straight days and the amp wasn't even warm when touched. Since I don't have a dedicated circuit, the amp's 95% power efficiency really help. When I first had the amp, I did experience ground loop hum. After I lifted the ground (by removing the ground wire from my PC), everything went silent. This amp is driving the Tyler Acoustics Linbrooks with outboard crossovers by the way.
Disclaimer: I am in no way associated with PS Audio or a dealer. I am just a very happy audiophile who bought an outstanding product at an affordable price.

Good luck with your search for the perfect amp!

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.
