This may be a bit of digression, but I agree that the B&W range is not up to the performance. My HiFi journey started with JBL Floor standers but then could not blind myself to the B&W hype and so owned DM series, 601S3, 686, 685, 684, CM7, CM1, CM9 in that order. Out of all these 684 was the only one which I think was worth consideration.
My current take on B&W speakers is that do not consider anything less than 8 series as the tweeters in the entire rest of the range is too metallic sounding to my taste an drove me crazy after 20 minutes of listening. However the 804D are my favourite of their 8 series as they are at the cusp of the price to performance.
Ofcourse, if I have space (and money) I would buy Vivid Audio!!
