What amps are out there that are Class A, 50 wpc into 8 ohms?

This is NOT a buying advice question.

This is a purely theoretical question. A friend and I were trying to figure out what is available that is:

(a) Class A 

(b) 50w into 8 ohms or better

My guess is that the answers will be Pass, Sugden, and then very very expensive things like Gryphon. I'm curious to see what folks come up with.

Just for fun.

Thoughts?

Luxman class A are up to 30w in class A if I am not mistaken,

after that they are a/b.

Clayton Audio has a stereo amp I owned S40. It can put out 50 watts channel into 8:ohms with the more robust power supply upgrade.

Zesto BIA 200 - 100 wpc Class A tube amp.

The ad copy says "Class A". I can’t tell if "Class A" is it’s operating mode

or if is just "Really good".

Found another: Zesto Audio EROS 300 Class A Mono Power Amp.
