Thanks again for continuing to take an interest; the CD-player-with-no- connections experiment is something I should've tried a long time ago.
Meanwhile, as for reconstruction, yes, basic systems of the sort you've described have been tried in the past with the same result, and have been repeated with different configurations of equipment -- but I *am* willing to try again in the interest of clarifying the data a little. (Tried Arcam CD-23 directly into Naim Nait5i, same result; tried Onkyo CD-changer directly into Primare SPA21, same result.)
The difficulty is with what that leaves, which doesn't seem to be strictly possible:
The problem exhibits many of the same characteristics as static electricity, in that it builds up continually and then dissipates all at once, and only under certain circumstances (disconnecting or, in some cases even just wiggling, the interconnects). I've even had some luck recreating the problem, or something like the problem, artificially: when I had zero-feedback monarchy power amps, I could induce 60-hz hum by having a Jensen CI-2RR ground loop isolator installed between the preamp and them, and when I broke the connections to the CI-2RR and re-established them exactly the same way, the hum would be gone completely.
The trouble is that each time I say this to someone who knows what he's talking about -- each time I say, "Now, doggone it, Joe, something pernicious is building up inside the system in just the same way as static electricity, and can only be dissipated by severing the interconnects," that person sooner or later has no choice but to say something not unlike, "that's not possible."
