I need to upgrade from my aging Mission 731 bookshelf speakers, for asthetics if nothing else. I onced test drove some Wharfedale Diamond 8.1's which I thought were awful. What I like about the Mission is the bass and they have been a great rock speaker. I put together a shortlist Mordaunt Short MS912 Monitor Audio Bronze B2s B&W CM602 B&W DM601 S3 Kef Q1 Anything else I should consider? looking to spend upto £300, anyone give me a kick in the right direction for rock listening?
