Several small caps (high quality ones) work better than one large one, you know that already right? I guess I am nitpicking, we all know a receiver as high end as the SR-18 is, still has to compromise in order to fit everything in one box. One question ends up being, with those compromises, could they sound as good as separates? I know they do, not for all, but probably for most home applications.
By the way, I don't want to open up my 4BSST, could you post some pictures for me, please?
