BethR,
zathras is sidekick, not hero.

Well the reviews here and elsewhere, have been so positive, that I've ordered 2 T-amps. A buddy also wants one, so we made the $100 Parts Express minimum.

I'm getting a 13.8V/3A power supply locally. Its been recommended here, so I hope it won't fry the 12V T-amp.

One of the main reasons I ordered the T-amp is because I've read people say that Pioneer amps are not "musical" and I'd really like to hear the M22's using something better. I've got the VSX-D812 A/V Receiver. It has pre-outs for all channels. There's something I want to try after I've tested the T-amp in its normal configuration. Take the left speaker RCA pre-out. Split it using a RCA splitter. Then use the Dual RCA jack/3.5mm stereo plug on the other end to send a dual-mono signal into the 1 T-AMP. Hence, I'll be using both channels of the T-amp to power the M22's. I'll just combine the 2 negative wires from the T-amp into 1 banana plug, etc. Do the same for the right speaker.
Now will the power supply be able to handle 2 T-amps?
