Yes, am getting old eyes too, now when I solder I need to take off my glasses and put up a lot of lights! So I must have mre then 10 LED flash lights...
What I did usually was to replace the rectifiers with the FR type, increase the caps right after the FR AC rectification, before the switching is done. It does improve the sound a lot. I tried plaing 0.047 uf Russian Teflon there, and yes I could here the sound becomes cleaner and clearer. Of course iwill also try to find out which parts to eliminate, such as op amps and lytic path coupling caps.
I recently bought a Pioneer A600 DVD players, and the surface mount parts is perhaps half of the usual SM types... I think my time to tweak is probably numbered!!

Best Rgds
