Balanced Low Power Tube Monoblocks?


I'm interested in suggestions for balanced, low power (let's say 60 wpc or less) tube monoblocks.

For example, the Atma-Sphere M-60.

Power tubes other than 300B are preferred (due to the high cost of NOS 300B tubes)

Others?

Almarg, can you point to a solid state amplifier model that mentions output impedance in the specifications?

I've done only a quick search, but neither Pass Labs nor Bryston publish this information.
TVAD -- What is most commonly specified is damping factor, which is almost always defined as output impedance divided into 8 ohms.

So assuming that the specifications do not indicate that damping factor is defined relative to an impedance other than 8 ohms, just divide the specified damping factor into 8 ohms and that is the output impedance.

Example: Damping factor = 40; output impedance = 8/40 = 0.2 ohms.

The Audio Mirror amps do seem like a good deal. Thanks for pointing them
out.

I decided to break the rules and buy a pair of single ended George Wright
Signature AU-15 monoblocks.

George made great, underrated stuff. I owned a WPP200C phono preamp,
and spoke with George on a few occasions. It was a bit of a sentimental
purchase.
Tvad, "It was a bit of a sentimental purchase."

Those are ALWAYS the best kind. Somehow, the music and enjoyment seems to transcend the equipment in these instances. Best of luck with the new babies Grant!
