I'm replacing my bookshelf speakers and tossing up between a couple of choices. I have a Marantz pm6002 amp and am replacing my mordaunt short 902i. At the moment I'm thinking the wharfedale 220 or tannoy dc6. I own some tannoy F4 and was fairly impressed with those for the money. Has anyone owned the 220 or dc6 and has opinions? Thanks.
