The best speaker you ever heard?

best or not it's depended on your mind and your ears?

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.

After having listened to Apogee Divas for the past 16 yrs, I heard a system at the 2005 CES in Vegas from McIntosh Labs that blew me away. It was a Proto-Type of their Flagship Speaker, The XRT2k....they sounded really exceptional.
System had 110 perfectly matched mid/tweeter drivers @ side, and a seperate bass column w/ (6) 12" subs @ side. This will be the next step in my audio evolution. The sound was awesome.
