I have the KEF 2005.1 system and was wondering whether anyone knows if the 2005.2 system is significantly better. My understanding is that they did some tweaking with the speakers, but did a lot of work on the sub. I've always thought that my sub on this system was nothing great, so I'm wondering whether the new sub is a big improvement. Alternatively, it may be how I've set up my sub. If you have any advice on the recommended settings for the 3 rear nobs, I'd love to hear it. Any thoughts would be greatly appreciated.
