The best speaker you ever heard?

Fcrowder, the Quads driven by a pair of Jadis 80 monos, HP of TAS once called a match made in heaven and by golly, how right he was!

OK...here goes. I will try to make this to the point as possible: The Infinity Servo Statics 1-A's were a shocking eye (ear) opener....I never thought a speaker could be so clear and clean and have such a powerful (gut strong) bass....then came the Infinity/Maggies QRS/1-D's....wide,wide stage and very uncolored. The match between the infinity mids and tweeters and the magnaplaner base panel was awesome! What a spactacular system.....The infinity RS 1-B's (my current speaker) was the little brother of the IRS.....it was 1) more affordable 2) retained the wonderful mid and highs and the base went to the basement and moved tons of air.
I am considering upgrading to the Piaga's P-10's.....heard then briefly and will hear them again soon at an audiophile group I belong to...but boy what I hear (briefly) had tremendous promise!!!!!Transparancy, clean, uncolored, efforless.......it's sings!!!!!
But the best I've ever heard (at a dealer showroom) was the Levinson HQD........at Lyric Hi-Fi about a 1000 years ago (lol)....sounded at one point to be really...real.
Anyway, anyone want to comment on the Servo's? QRS/1-D's? RS-1-B's?, Piega's?, HQD's???????

RWD, WOW, now you are talking! I used to own the Servo Statics 1-A, sans the bass however, used the panels for the mids and highs and mated them with the Maggie bass panels you mention, which I still run today, together with my Quads. Those highs and mids were incredibly pristine, smooth and clear. I also attempted something like the HQD, but since I could not get Decca ribbons, I used those by Dick Sequerra, and boy did that system sing. Voices, small Jazz combos, chamber music was- you've said it- occasionally frighteningly "real". The Servo Statics died, the highs went first and then the bigger panels and spares were not to be had. The Quads were exchanged for the 63's, and other ELS which I still run today in a stacked version.
Cheers

Avantgarde Trios are the best yet to my ears.Too expensive, though. The Avantgarde Duos are a great second choice. You can't skimp on electronics, however.

b&w nautilus 801 with krell fpb600/hr and ml31.5 / 30.6 combo....'awesome' is the only word to describe.
