Before I take the plunge, 2 questions, please: 1. Is it a done deal that Tannoy DC2 (floorstanders) and DCC centre speakers (both with supertweeters) will sound better than the KEF 3005 lifestyle system? 2. Will the Tannoys be easy to integrate with pretty much any sub? I have the Velodyne VX10 (but may upgrade in the future. )? Thanks, in anticipation.
