Well...That's interesting. I'm not too surprised that making the changes you describe in a preamp affects the signals.
The speaker on the other hand is a real puzzler. When I get some time I'd like to try that. Does the effect increase with the imbalance between the legs? I'm thinking a procedure might be:
1. Construct a cable with a substantial imbalance, perhaps 4:1. I've got some Kimber Kable I'm not currently using that would be easy to rig up.
2. Listen to it.
3. Swap hot and cold at both ends and listen again.
4. If the sound is different, grab a beer and try again.
5. If the test repeats, reverse end for end and goto step 2.
Ultimately it's a passing out ceremony, but what fun...Do you think that would reveal it? I just can't imagine any mechanism that would alter the sound of an isolated speaker by switching hots and colds since the loop impedance shouldn't change and the load is balanced (being isolated). I can hardly wait to try it.
