I have been listening for several days on a master-gd 8 amp fed by a mytek stereo192-DSD dac. Thats a powerful solid state amp with a very (IMHO) bright DAC. I don't find the OPPOs coming anywhere near the HD800s in terms of brightness so far.
Yeah we have to just forget comparisons to hd800.
Need comparisons to LCD.
I guess it's because hd800 is sort of a Pinnacle standard in soundstage & clarity. . I guess.
Edit:
Also Ur setup seems ideal for the oppo. .
