Hm, I understand what you want to say , but I am not sure that he is the only one. I sold P3ESR and bought ProAc Response One SC. Why? For similar reason. P3ESR have so much good things to show, but I always felt that it hold so much behind it. Also, impression that I always listen to speakers with them distract me to much from total enjoyment. So, I rather enjoy them partially from time to time when timbre is important, but not dynamic. I hope I should find in bigger Harbeths what is missing in small Harbeth, so at the moment I have 7ES-3 at home demo which although it have something, it is very slow and weak from my subjective point of view. Tone is good, but when it's busy material, it sounds like someone has sucked life out of it. Before 7, I heard new M30.1 which has been my first candidate on the list, but these are really typical Harbeths and for me although bigger, they are not so good like P3ESR, but then again, this is all subjective. I cannot ignore so laid back character and I cannot accept cliche that Harbeth is right and everything else is wrong and sound in a forceful way. I do respect Harbeth designer and everything he do, but somehow I believe that with Harbeth speakers I listen tones and not music as a whole, so I am not surprised they are much more popular in Asia. For me it is like owning a car which can go 25km/h max. and trying to convince myself that anything faster doesn' t have sense.
It's a pitty as I found some qualities in Harbeths, but still not enough for me.
Cheers
