Thanks, dude.. it must be chilling the butt in Canada huh?
PIMETA, another sifoo from another thread on Philips Headphone thread also recommend this. Gonna take a peek...
Edit: TREAD, what's that huh? Something like jumper wire?

tangent has a nice collection of audio articles. refer
here. there stored articles about PPA, PIMETA, MINT and META amps.
TREAD is a Linear Power Regulation Circuit based on the LM317. but that requires about 3V drop across the regulator for it to work properly and without hum. so that's not really a choice if you're thinking of using the 12V rail. you'd be better off with a low dropout voltage regulator for that usage.
and i doubt that toroid ferrite core would help in smoothing switched power.
