I have an X-Fi XtremeGamer low profile, so i order some LME49720HA to testing.
Also the card has an extra 3.5mm jack for 7.1.
Skipping the desoldering process, Lme in plastic improve adaptor.
4556a Ttsop8 was removed, its just a little tricky.
Direct solder of the opa to the board.
RMAA doesnt says an accurate veredict cause recording settings in x-fi panel affect results, i didnt notice but i made a mistake taking samples cause that there´s no detail of RMAA for the moment.
THD change from 0.0038% to 0.0022%
IMD + Noise, 0.0058% to 0.0041%
First, changing the opa doesnt affect the ouput volume i think changing lme is "compatible"(also is the same opa change of xtreme music).
I tested some flac of Miku Hatsune, voice pitch are more clear, loudly and defined, highs tones just sounds diferent, like separed and distinguible, bass are more contundent.
Im not an audiophile but i can notice that changing the opa improves the sound around 20% just worth the efford.
