I wasn't looking for info but stumbled across a few instances online mentioning the Nobsound MS-10D

It looks a lot like the one Monoprice sells, yes?

Apparently the tubes are only for show; audio never passes through them. It's not a hybrid design. You can remove them, and the amp is cleverly designed to then not work, but it actually lacks such things as transformers or rectifiers. And ya gotta have that for the tubes to do anything useful beyond look pretty.
