Aloha,
I just changed the power supply electrolytic capacitors in my apheared/cmoy amp from the 220uf to 1000uf. JMT was my inspiration in doing this mod, my first. I was surprised how much it changed the sound, the low end in particular. The 1000uf cap gave the low end a noticable boost, a little to much for my taste. Actually, it's kinda boomy now. Also I noticed a decrease in the extreme highs. By the way, I am running a Sony D-EJ915 (line out of course) into this amp (powered by 16 AAs) and out through SR60s. I'm not really happy with the results. But I can see if the headphones you are using could use more bottom and less highs then this is the mod for you. It's 4:15am and I'm kind of tired so tomorrow I'm going to try a 470uf instead of the 1000uf to find my nirvana. Though the results weren't what I was looking for, I'm glad that I did it because I learned something new about audio circuit design.
