Update on the caps - Man do these guys take their time burning in. At first they sound amazing, but then pretty soon they go through a "muffled" stage that lasts a long, long time. I've been running my system at least 12 hours a day since installing the caps and they are only 'just now' coming out of the muffled stage.
So, how do they sound? It's the closest I've ever gotten to "SET sound" in my First Watt Burning Amp. Firm, clear, transparent, and a slight glow that makes everything more beautiful. They are not soft sounding, in fact they are very dynamic, firm, and clear. Where the Clarity Cap MR caps were a touch on the analytical side, the Jupiters are a touch on the golden side. Very slight. And it makes listening to music awesome.
PS, someone PM'd me about some other copper caps but it got deleted by accident - please pm me again.
