  I had the same doubt in the MF A2. I ended up just bypassing the PS rail of the op amp and the result was freighteningly good. See by post above on bypassing.

    Interesting! What kind of results did you get? Specifically, how did you do the bypass?

• You could use an LT1365 (DIP-14) or OPA4134 (SOIC) via Brown Dog adapter. nt - Dad 16:44:33 06/13/04 (4)

    Does BrownDog make 14-pin adapters? I could only find 8-pin. Also, what do you think of OPA4132 and OPA4227/8?

      Here is a link to the SOIC to DIP-14 adapter. I haven't heard those particular opamps to comment on them but I would venture that teh FET based (4132, 4134) opamps will sound better than the current one you have.

        Excellent! Thanks. Do you know of single-to-quad adapters?
