Hello everybody!
I would like (or better, i've tried with no results) to upgrade the 4 opamps on my es9023, currently there are the cheapest TL072.
I've tried to put in four LME4972 and also the OP275, but in both configurations they generated distortion.
To remedy at this i must take down the volume of dac, about -30db than the TL072..
I've little technical knowledge but the datasheets of all this opamps seems compatible with each other, have you any suggestion about causes?
P.s. i've already tried to solder 0.1uf capacitors from opamps power input to gnd to prevent autoscillations without results.
Many thanks!!
