Or, it just may be the fact that - for your ears - the B&W's sound better! Now you know why whenever anyone asks which speaker should I buy the general concensus here is "audition, audition, audition". There is probably nothing wrong with your hearing, it's just the way your brain interprets what it hears. That's why there are so many different brands & types of speakers - because we all hear things differently.
When I auditioned speakers, I listened to Energy, Polk, Klipsch, Martin Logan, Vienna Acoustics, Def Techs, & Paradigm's. But when I heard the B&W's, my ears felt like they had arrived home after a long strange trip! The other speakers were all good, but there was just something about the B&W's that sounded "just right". I have a complete B&W HT, the 602's, LCR60, & 600's + a Hsu sub, and couldn't be happier!
I get the feeling that you are under the impression that since you can get more expensive speakers for about the same as the B&W's that somehow the Focal's are better. If you can, step away from the dollar amount and ask yourself, "which is the better sounding speaker". Remember 2 very important things; it's your hearing, and it's your money. Get the speakers that sound better to you. If the Focal's sound better, great, enjoy them with the knowlege that you saved a lot of money! If it's the B&W's, great, enjoy them with the knowledge that you save a lot more money! What a great win/win situation!
