Well to quote you all, I am no HiFi writer or reviewer, but I listened to the PS3ER and these can play music, maybe in the room in the shop, which was quite big and open, they were possibly undersized for the room, however I did not listen the compact 7's as these are quite big speakers, the picture on the web site does not give this impression. What I did try was the M30, wow, wow, wow, these are stunning and I mean stunning, when we swopped over from the 3R to the M30 the first I noticed is that they sound louder and fuller at the same volume level on the amp, there is no distortion and all the instruments and voices sound incredible, the music is just awesome, which is what it is all about. This is not a massive speaker and sits on a smaller sized stand, it measures 460H x 277W x 285Dmm.
I have just put this to the top of my list, its more than I wanted to pay, but in the long run it would be worth it.
The only reservation I have is that my room is alot smaller than the shop (10.5ft x 10.5ft), I am pretty sure they will perform in there, its just if they will look right in there, if you get my gist !
All in all though the Harbeths are a wonderful speaker, you can see why people say things like they disappear, and more so you dont see many pairs for sale secondhand
Cheers
