OP-AMPS CHANGE (PART 2)->NE5532 to Muses8920->different, more musicality, very soft..
first, absolut no comparison to the OPA2604 (in any case to those i had here)->they were really bad..
These Muses8920 have a great musicality, and a very fine resolution but at present it lacks of something (in comparison to the NE5532)..
(so, here i have stop for a moment, because i have to re-check them in a few days..)
more to come…
