The best speaker you ever heard?


In my opinion, the speaker is by far the most important part of the audio system. After all, it is the only part you hear. OK, the other stuff really matters a lot, but without a great speaker... No go.

I am a bit 'speaker-obsessed' I guess, and now I am wondering: What are the best speakers you have ever heard, and what made them the best?

Infinity IRS Omega, the last of the fame.
Heavily upgraded (new Auricaps, coils, DH Labs cables etc...),
I own it and I think I may be the only on in the states with a pair, as it was only marketed in EU and Japan.
Steve01s$, where did you get to hear them? I guess this is an instance where you really do not want to hear them, because once you have you are hooked. I have the LaCampenellas now and find them outstanding. Furthermore, at only 187 pounds each, they are manageable.
MBL 101-D's is by far the best. These were the best back in the 80's, and still the best today by leaps and bounds.
The Avantgarde TRIO. By far the most musical, live sound I ever heard in my 43 years. The 100+ dB efficiency speaks for itself. Roll the tubes to your heart's content, hell, roll any amp from 6 watts to whatever. Over 25 years I've heard all the big Wilson, Apogee, Soundlab, the Infinity Reference model towers from many years ago; the Avantgarde is the nicest. A close second for me is the Magnepan 20.1 and 3.6, but certainly far different animals, at least in terms of efficiency, but for the money, nothing comes close to the big Maggies.
