Hello,
Should i replace my NAD320BEE AMP capacitors after 18 working years ? it still working but i heard many times that electrolyte capacitors loosing their power (getting dry actually) and it influence the sound. Please don't ask me if the sound got worse over the years cause i really cant tell, i just not so happy with the sound generally.

If it sounds good to you I would leave them alone .if you take the top off the amplifier if the capacitors have swelled or are leaking then change them .
if you have full sound no dropouts or noise there probably ok.

Bought my Cyrus One in 1991 and still sounds good compared with my 4 year old Onyko. The only time I removed the lid was to give the selector switch a dose of switch cleaner.

That's doing well. You've got another 11 years on my 20 year old Cyrus 8 - which has had no maintenance whatsoever (v/c never needs spraying).

I did change the electrolytic caps in a Quad FM4 tuner though. Noticed they were leaking when I changed the backup battery. (No noticeable effect to sound before or after replacements though).

You're probably OK to leave yours Arigo....unless you fancy changing them.
Of course, if you're going to bother, make sure they're the same capacitance value and the same (or higher) working voltage and at least as good quality as you currently have.
