Thanks. Mmmm...do all of them require soldering work? I am a klutz with DIY i.e. never done it so I don't really want to do anything that isn't just a clip on. But I'm intrigued seeing that the sound does change by a fair bit.
The OPA2111 and OPA2107 in DIP are just drop ins. The soldering work I was referring to for the OPA2107 was to bias it into class A (two resistors on top of the chip pins - and fairly precise work).
