Heh, the Monster amps are also made by ATI.

Apparently, because of the LCD displays that Noel Lee specified the amps HAD to have, they have problems with noise and are set up in a nonstandard way to resolve the issue.

Because of this, the amps won't pass THX spec, which doesn't sit well with Noel Lee and he has been trying to get THX to change the spec, hah good luck.
