With the change from electrolytics to the ASC 100uF caps I thought I might get some areas improvement but the cleaner and more dynamic sound, of what I already thought was very great, just leaped.
I tried 2 100uF ASC 370 ac volt rated caps for the B+ with one 30uF internally right at the junction of the B+ for the opt. Ripple was slightly higher than stock at .73 on one amp and .84 on another. The sound was good and the hum was not louder than before, which is very low. So I added a third cap and the ripple dropped to .54 and the overall sound went from a little better than stock too much better. The hum is so low that your ear has to be within a few inches of the speaker to pick it up.
The snap to the music is precise and crisp. The sound is still warm but in a natural way. This is a cheap upgrade that out does much more expensive changes. The caps are external of course on an 18 inch detachable umbilical. It will be very easy to change cap if I desire, which is always fun.ja in clear and warm, Tucson, AZ
