[sdiy] audio op amp replacement

 > Adam caught wind that changing these out to OP275s would improve the 
sound quality.

Tell Adam to keep the 5532. The OP275 may well have less current 
consumption, higher input impedance and better DC specs. But for sound 
quality the 5532 just sounds better. At least to my ears anyway...

This does assume that the manufacturers of the desk have kept the 
resistance in the circuit surrounding the 5532 accordingly low. Anything 
above 47K and you probably will be better off with the OP275.
