Okay, I've been waiting for years to rechip my board. TL072's with the odd 5532 are the stock chips. Are you saying that just replacing the chips with OP275's nets nothing over the 5532's without transistors helping each stage? Maybe to up the ante on the TLO72 stages without increasing the current draw? (I'm going to upgrade the power supply regardless.)

I'm probably going to end up socketing a couple channels, taste testing, and repeating, but it'd probably help if I had a better clue what the hell I was doing instead of semi-randomly doing replacements, especially with the potential for oscillations. Where do I read up on using monolithics, from the basics?
