The best speaker you ever heard?

Well, I have heard a good speaker finally. One that does not have a boxy sound, that has a sharp leading edge, that has the pace of music, that images realistically, that has all frequencies arriving at the same time, and one where the speakers themselves vanish. The only problem is that the LSA Model 10 driven by the LSA/Exemplar components cost $80k.

Dracule -- a rule of the thumb: when driving TWO spkrs together inside a venue and feeding IDENTICAL signals, you get +6dB over the rated sensitivity of each spkr measured individually. But in the Synergies case, the spec is for music spl -- i.e. not identical signals, so the extra gain is less, say 4-5dB over the single spkr. So, the single spkr would spec 95-4 or 5= 90-91.
3dB: to go up (or go down) by three dB, you double the power (halve the power).
Cheers.

JMLab/Focal Utopia with the Be tweeters's (any of them depending on your room size). Most transparent speakers around, high sensitivity yet full range and great with most any high quality amp (particularly tubes in my experience). Several cosmetic options. Not cheap but worth it.
