I had those KEF's in my first system. You will like them--everyone else did! It was also great advice for you to find some old Vandersteen speakers (1C or 1B would be really great) as well as looking at what Ascend Acoustics has to offer.
The KEF's will be very very good, Vandersteens will seem a bit more musical, and Ascend Acoustics will seem a little bit more alive. All three, you will be drinking champagne for beer money and nobody will be the wiser
Good luck--you can't lose!
