Freaky speaker experience:

I have the Nuforce 9SE pre's and amps. I had them attached to my Focal JMLABS 936; bi-wired at the speaker but single ended at the amp. They sounded soooo crappy (tinny, bright, fatiguing) that I was ready to toss them off the second floor window. :) Could'nt understand. For kicks, I single wired it using the original jumpers. Now they sound awesome. About 10 cd's later still awesome.????? They sound different but as good as my Totom Mani's. Any ideas about the bi-wiring? Too much juice going to the high end?

bokfudo has this figured out...the 'feature' of bi-wiring does not guarantee any improvement.

Any chance you had one set of drivers hooked up out of phase?

I'll second Rleff. Sounds like one of the woofers was out of phase. If everything appears connected right I might go so far as using an ohmeter and checking the cables.

If she's game, perhaps your wife could change from single to bi-wire a few times without letting you see. She should also not change them at all, just pretend to, a few times. Then do the same for her.

I'm open to there being a real difference with bi-wiring (that couldn't be achieved with a single run of the equivalent gauge of a single wire), but I've never heard a convincing explanation for why there might be a difference. The explanations always sound very hand-wavy to me. I'd like to seem some actual math.

Even so, I made some "true bi-wire" cables for when my new Vandersteens come. Cost for materials was under $40. By "true" bi-wiring, Vandersteen means keeping the two runs separate by at least an inch instead of having them in the same jacket. But I did this more because I could than because I expect to hear a difference.
