My Big Amp

I heard this amp driving a pair of Dutch Audiostatic electrostatics, speakers I had heard several times with different amps.
I was quite impressed with what the amp did and expressed it to the owner.
When later he offered it to me for sale, I did not hesitate and grabbed it.

It is a private build, and frankly nothing was known about it by the seller in this case by me.
It is really big, and weighs 35 kg. It has a Class-A switch.
I am impressed by the build, three levels high, at the bottom 8 big electrolytic capacitors per side.
[after a closer inspection using an endoscope it turns out there are 8 electrolytic capacitors per row. 2 rows per side, total for both sides 32!]
Left and right are for as much as I can see fully separated.

So no power figures to brag, but I measured power consumption which I think is fairly modest: about 55w in AB driving the Centaurs and just under 300w in Class-A.

I've had a brief listening to the Centaurs with a lesser CD player connected and no sub. The sound is okay, stable, wide, relaxed. In Class-A I could go with the volume knob to about halfway without any strain and had in my perception a very good listening volume.
I think it will do well with the Calipers.

Let us know how it goes. I'm a big believer in big power supplies and a lot of caps.
Good Listening,
