I have a factory upgraded Accuphase C200 and a C200 that my local tech upgraded. The private upgrade is about 10X better....no comparison. The original used elna caps...I had Nichicon gold installed. I am lucky as my local tech was a trained Accuphase dealer. On the C200 there are about 22 caps that need to be changed out or bypassed in the sound path. Also the noise floor can be lowered significantly.
How many of you upgrade your preamps and amps?
I was just wondering how many people have upgraded their equipment by a non factory tech. I have recently upgraded some older equipment with very good results. I also presently have a Accuphase P300 amp that will have the electrolytics replaced with black gates and Mundorf M-Lytic caps installed. With the higher cost of great sound...it seems to be a excellent way to go.
