I believe the SoundOdyssey stage 2 uses the OPA627. Their stage 3 uses the zap filter.From their website the zap filter bypasses the Opamps altogether and replaces them with a class A analog stage.
Don't know if this is totally relevant. However my CDP's balanced output runs thru the Opamps. The RCA's (like the zap filter) bypass the Opamps and run in dual class A analog.
To my ear the RCA outputs which bypass the Opamps are much quieter. Very black background.
This may or may not be the case with the MH mods. But something to check into.
