ES9038Q2M+Skysong/Singxer XMOS-USB-bridge->(final) thoughts/settings tone optimization

so, 😉
after i tested a lot of different op-amps+filter-settings on the ES9038Q2M (Blue) lately i came to this (final) conclusion:
The Muses 8920, are/“sound“ brilliant on these Blue, i think they are lately called „YJ-ES9038Q2M“ Q2Ms..
much better as with the NE5532 or the OPA2134 for example (other possibility would be the AD797, LMEXXXX (see earlier post))..

by that to provide the Skysong/Singxer USB-bridge with an external 5V power supply also boosted the overall performance of the Bridge by 10-15% !!
absolutely to recommend !! 😉

absolutely wonderful bridge (read elsewhere they should be the „finest“ with the best XMOS-implementation)..(i have the version with the golden crystek cchd957s))..

the filter-settings have here for me not such an impact on the sound/tone, guess 2-3%, max 5% 😉 , but u can hear it if u want..but the differences are really „paper-thin“ (on other DACs/millboards it could have a greater impact)..
by that „kennyliveforever“ made a great post in the forum-> http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=64 about how to include the „original“ essabre-driver (I-Sabre-K2M) for the ES9028Q2M in Volumio (and then maybe in other audio-distros)..
so far for now !!
