Any IPR owners want to share some tips on how to tame the rattle and clatter of this amp when it's sitting near a cab turned up past a modest volume? Should I just open it up and start applying foam tape between every post, stanchion or joint? I've also placed some non-sticky foam between the preamp and the IPR, which helped, but there is still some rattle coming from inside the amp. This thing was clearly not designed to sit next to or on top of a bass cabinet in a rack case. But that's ok, this problem is solvable, I think.
