Need a few more details ie room size and buget also sats or traditional speakers. I opted when heavy discounted for a Onkyo 606 amp and Quad-lites speakers with great sub, excellent amp now replaced by the 607. So budget amps from Yamaha ax763, 863, Onkyo 606, 706 , 607 and Denon 1909 soon to be replaced by the 1910. Play.com might have the Sony str 2400es at £429. for speaker something along the lines of the Q Acoustic 1010i with additional upgrades like the 1030i,1050i, floorstanders for the fronts. Sats Kef 2005.3 or 3005se would also go good with those amps. If you fancy spending a bit more i would have an audition of the Tannoy Mercury customs. I think that Quantum electronics might be doing a good deal with the Q Acoustics 1010i and Onkyo 607 for around £850.
