Last week I bought a Canton DM55 + Yamaha SRT700BLB subwoofer to replace a Tannoy Mercury V1 bookshelf speaker set-up and I'm really not impressed with it at all. The drop in quality for music playback is too big. I need a compact system (the single reason for getting rid of the Tannoys) with about £300 to spend on the whole thing. Considering these two, with the rest going towards a receiver: Denon SYS-2020 5.1 Speaker system - Superfi / PIONEER S-HS100Black 5.1 Speaker Package Would they big a improvement over the Canton? Are there any alternatives? I've had a stereo speaker set-up for the last 10 years so I'm new to all this.
