Right now I have two big amps, grace m902 and Lisa III
For grace m902:
It uses opa2134 opamp. If I modify it to 2xopa627 with BDA (surface mount), it should give a lot more dynamic and mass of medium. Maybe some caps replacement if neccessary but I doubt if this is worth to do or it will be better for sure.
For Lisa III:
I checked its buffer output and it's class AB which cause sound narrowed down comparing to home amps. If I modify it to class A buffer output, it should sound more fuller but costs with 15-20 more ma. What do you think?
