The best speaker you ever heard?

A purely subjective answer. I have heard many that can be considered the best. I find a certain ^ 150,000 loudspeaker sterile and clinical in sound. I have heard a $15,000 loudspeaker that brought tears to my eyes...I do not mind saying that it was the Gemme Audio Katana. Sometimes, magic does exist. Now, the loudspeaker that brought me to my knees was the Infinity IRS from the 1970s. I still remember the experience to this day. THAT experience brings to mind the greatest speaker i ever heard. It was the 70s, no one had done anything like it...and if it stays with you for 30 years you know it was special.

Speaker is not the most important piece of the pie - not nearly. Take a decent, competent speaker then it is all about the source. I have seen this in practice WAY too many times.

Actually, your ears are the most important piece of the pie.

i was at a demonstration at "the mountain" bose factory. in a semi darkened small theatre [100 seats]the audience listened to some 901 series 5's. most people we pretty impressed and assumed the set up had to be tweaked but.....? then 2 people walked in and theatrically removed the "fake 901s" and exposed the fact that we were listening to 2 acoustic waves on pedestals.suggestibility and eye over ear bias? true story....
