For me the first things is remove the digital filter
And the sound sucks becouse original analog stage would have to be recalculated. I've done this many times and without separate analog stage (OPA660 or AD844 would be good example) the sound is worse than with digital filter in place.
And yes I know, everybody is raving about non os mods lately, but it's not always for the better
zygibajt said:I use Philips CD 960 which is just identical except for the front panel design. The bottom line is this player so far is the best sounding CD player from old Marantz/Philips players based on CDM drives and TDA1541A.
but I had Philips CD 304MKII with all the same mods applied and is much inferior to Philips CD 960/Marantz CD 94
Distortion of CD960 is worse than CD304mkII & CD650
I have three CD960 and three CD304mkII.
