  2. I've been wondering about this for a while now. Why is it that some amp designers like to use a single, large cap (a Rubicon 10,000uF, 63V cap for instance) and some prefer to use several smaller rated caps. Now I realize that caps aint caps (and I'm only looking at electrolytics here, because I'm interested in the power filtration/delivery aspect) and some are likely to be better behaved than others but what is it that makes one cap better than another, or, just for instance, what about an amp that uses 6 3300uF caps makes it much different than an amp that uses 2 10,000uF caps? (apart from the slight difference in the total I mean) Do smaller rated caps discharge faster? I notice that the Perreaux Audiant series uses a bank of smaller caps instead of 2 or 3 big ones, and the ME amps use a bank of caps that are smaller than I thought they would be (I think they are 5000uF caps, where I sort of assumed that they would be 10,000uF because that is what most other amps use) and, well, it got me wondering why. (I realize that cost will likely come into this but I'm hoping it isn't the only reason, because that would be boring.) The Audiant and its bank of smaller caps. The Myryad Z142 and its much more standard layout of a single 10,000uF cap per channel.
