I disagree that all B&W speakers are bright, but it does seem to have that reputation. Having said that I do find the 700 series a little on the bright side, from a few auditions I had with them.
I had a pair of B&W CM series and they were not bright at all. I currently own a pair of B&W 804 D3, and I also don't find them to be bright. I have tinnitus and very sensitive to brightness in audio. The choice of source components, amps, and cables all contribute to the final sound coming out of your speakers. It's a time consuming process and sometimes a little bit of luck can help.
Anyway, good luck and hopefully you'll be able to find a solution that works for you.
