Loudspeakers are the most personal of all the links in the Hi-Fi chain, and change the sound of music in the most profound way, IMO. My first great speaker was the original Tympani I-U (I've never learned what the U designated, other than to differentiate it from the VERY original T-I), but was seduced away from it by the Fulton J, a loudspeaker with more and better bass (a cone in a transmission line-loaded enclosure) and the State-of-the-Art RTR ESL-6 tweeter, with the legendary Fulton Model 80 between them. It didn't take long for me to regret the substitution. Yes, taken section by section, the Fulton J bested the I-U, but those qualities proved to be less important to me than what the Tympani did that the Fulton didn't. Essentially nothing has changed in the following 40-45 years; either what large line-source loudspeakers do that point-source loudspeakers don't is of paramount importance to you in the reproduction of music, or it isn't.
