Hey guys, I am starting this thread because OPAMPS and card modding is really big right now and post about it just get lost in others threads. We can just keep all the questions and answers here for easy locating. I know many of you are starting to change out there opamps after Auzentech launched their high end opamp line. Others are changing their capacitors with better quality models..etc. Currently I am using OPA637's in my Prelude 7.1 and I considering modding the card quite a bit. Including but not limited to: New power capacitors (filters) Changing out or bypassing the coupling capacitors with higher grade models. and a few others that are secret. So....what up with you guys?
