I have the 606 as well and after debating and looking through the forums Quad-Lites popped quite alot and Q acoustics 1010i. So i went to my local store and listened to kef 2005.2 and Q acoustics has they did not stock any Quads. I much preferred the sound of the traditional speakers but felt the sub on the 1010i wasnt as punchy as i wanted. Then decided to look for similar size speakers and budget and went for the Quad-Lites in silver wow awesome sub costing £550 alone. Other packages now at a good budget would be the Tannoy arenas for style maybe still available at Richer Sounds or Tannoy f1 customs at Frank harveys. May be the Radius R90s and R270s at Peter Tyson silver available at a budget price all other colours at full price.
