The best speaker you ever heard?

You wouldn't be funnin' us, would ya, Dawgbyte? We have "Dawgs" here in Northern Ohio that wander in from the hills during football season. The team, especially management and coaches, as you've probably noticed, is persistently sad-sack. The colors of "rustbelt" seem to fit.

To put my answer in context, understand that I have been out of this game for the better part of 20 years, for reasons too complicated for this post. My "new" 2 1/2 (?) systems, accumulated over about 20 months, are soon to get the juice, however!

BEST: I think Mark Levinson's demo of master tapes on his HQD System at CES in Chicago about 33 or 34 years ago. That would be huge Hartley [sub]woofer units (15"-ers? Or was it 18"?)... stacked Quad "57" ESLs...and Decca (Kelly) ribbon [super]tweeters. Of course, the source may have had something to do with it... But, whew (!): "It's hi-fi, Jim... but not as we know it."

MOST MIND-ALTERING, JAW-DROPPING, FANTASMAGORICAL, and JUST PLAIN SCARY: Professor Hill's Plasmatronics ($10K a pair, and it seemed kind of outrageous!) at one of those same CES's. An ion plasma "tweeter" aboard, in case you don't know; and enough ozone to bleach the walls, I expect. Don't give me your quibbles about "integration"... The Roger Wagner Chorale, doing "Dry Bones", complete with Spike Jones-alike sound effects, could stop your heart... or scare the bejeezuz out of a corpse, and START ITS ticker! To this day, when some reviewer describes a ribbon tweeter as "lightning fast", I laugh.
