Thanks, I got that bookmarked.

On power supplies... I've always assumed we'd be running off an MOTM or 
similar power supply. Getting into power supplies would take me too far 
off course, I think.

In terms of audiophile stuff, Marshall Leach covers stuff like that in his 
Audio Engineering class. Some of you may know his name from the "Leach 
Amp."

See http://users.ece.gatech.edu/~mleach/ece4445

his analog electronic course is great too
