First of all, WOW!! Iv never heard anything where a single component is worth more than £300.
The one thing that stood out most to me was the new Kef 3005's or something. The sub and 5 satalite speakers were amazing, i was so shocked how good music sounded, the sub integrated so well with the speakers there was no dierection from it what so ever, it was just beutiful for music, and then when they played a DVD, again i was amazed at the quality of the movie sounds.
Definately guna purchase a set of these and the denon DVD player and Denon amp they were useing when i fork out on home cinema, i cant believe how awsome they were.
Oh, and best for music there was Linn i think, followed closely by naim. Linn's demonstration made music i didnt like seem listenable for days on end.
