Here is another tweak to try. I see from your detailed photo that the caps are supported by their leads. They are stout and strong enough to hold them up, but they are not rigid enough to immobilize them. Caps are sensitive to vibration, even inside an enclosure, and should be secured and damped. Put something under or around them to damp vibration: any foam or piece of insulation will work, or just a piece of heavy tape stuck to them. It will probably improve clarity, even though it might seem at first to dull the sound somewhat. That's a good thing: you're not really hearing detail, but distortion caused by vibration. You might be able to hear further INTO the music, instead of just a surface brightness.

Yes it bothered me that, due to available space and lead spacing, i could not secure the caps tightly against the board (the Arcotronic caps were also floating in the air, btw). That said, the leads are really thick and strong.
I thought about wrapping the caps tightly in Teflon tape but I should have done it prior to soldering them :( also part of me didn't want to hide the beautiful metal body :/ wrapping things up in teflon tape looks tweaky as hell ^^
I also thought about compressing a piece of sorbothane under each cap, but I'm afraid the sorbothane might react with the board material or with the cap's body, I don't see it as an endlessly stable material. I'll figure something out.
IMO Mortite sounds better than silicone. Might give it a try. T456

Some clear RTV silicone caulk does nicely in an application like this -- just add a small amount between the cap and the board and then let it cure fully. If you get a small squeeze tube (rather than a big tube that goes in a caulk gun), it's much easier to control the amount and positioning to keep from getting it all over the place.
