Hello.I have this CD Player Denon DCD 625.I replaced all the electrolytics with low ESR ones and raised the capacitance of the two big caps from 4700uF to 6800uf (C502) and from 2200uf to 3300uf(C501).
I changed C314,C315,C704,C705 with audio grade caps.
C503,C504 were not used but after reading the datasheet of M5290P (IC501) I added two 100uf low esr caps.
Should i use bypass caps of about 220nf in parallel with C501,C502 and 100nf in parallel with C308,C309?
Should i use bypass caps of 4.7uf+10nf on pins 1,3,8,16 of IC302 and IC303 PCM61P and 2 ic sockets for them?

Just swapping caps is not an ideal way to get better sound. Using low ESR parts can sometimes cause new problems. Sometimes famous brand name caps can make a circuit sound worse. I guess I would ask about each time you replace a capacitor, how do you determine if the sound is then better or worse? Measurements? Listening tests?
