This is the kind of answer I was looking for. I searched around the web for a while and found many people who recommend a cap. I read only a few who were against caps altogether, but not one explained why. I just got tired of looking around (plus I have more important things to do) and figured I'd get a good answer here. Thanks.
There are very few of us audiophiles around here. As a matter of fact, lo-lyf and I are about the only ones. For the longest time we fought and bickered about everything possible until we came to the realization that we just have different tastes in the same hobby.
