I'm planning to buy new speakers (only for music) and I was considering the B&W's 603 s2. I now have the B&W's 601i witch I love but they have a very small sweet spot. The 603 reviews tell me that these speakers have a small sweet spot as well, and that they need a lot of space behind them and placement is very critical.
Basically I have no experience with speakers other than B&W's (except for a terrible JBL experiment) and I'm looking for some easy on the ear but detailed and open, supple sounding speakers that are not as critical (placement wise) as B&W's (in the 603 price range)

Thank you for your advice,
Walker
