Topic: USB tube amp

[BobW]

A true triode will sound very different than a pentode run as a triode, according to the aficionados.
You can run a pentode biasing the three grids differently as a single-ended amp.
I find push-pull amps to be quieter, but I guess it's all about design.

Yup, leave it to the Chinese to pair 1930's audio amp technology with 1990's digital interface technology on the same box.
Now if they actually used a tube D/A, that would be something.
