Thanks for the advice,
I have just hooked the Kudos back up for a quick comparison and they are much more in control of the bass and the room.
Mid range is as good if not better than the SF's.
The treble is not as good.
Sound stage is much fuller but that might not be down to the speakers and more my room size, the SF's are physically much larger than the Kudos so the Kudos might be filling the space correctly and the SF's might simply be too big for the sapce?
I am not a fan of the GX speakers, the grills look naff.
I will try the Ushers and might try the Focals but £5500 a pair!!! ouch !! There goes my wifes Xmas!!
Cheers
