Pricepoint the 5005.2 are the best price imho i like the sleek elegant cyclinder shape speakers, and they do look fantastic mounted either side of the Pioneer 5090. Sound wise to me they offer a better soundstage and good crisp dialog and at the same price i would opt for them especially for wall mounting.The Kef 3005se have been the better seller due to earlier pricing of £300 or more pounds cheaper and wider coverage due to the amount of awrds it picked following on from the success of the 2005.2.Go and audition to make your final choice and what amp are you looking at.
Much better detail and improved musicality to my ears over the 3005. The sub ultimately lets both packages down for music.
The 5005 with the PV1 sub was a great style setup for films and music. In my opinion not as good as the Tannoy Arena though, so if they're sleek enough for you and you can still find them well worth a listen.
