B&W vs PSB


I have had a pair of B&W CDM 7NT for years and have been happy. I have an opportunity to pick up a pair of PSB Synchrony One's. How much of an improvement should I expect?

$2,000 (B&W CDM 7NT) vs $4,500 (PSB's). For that price difference I should expect a significant improvement.
Thanks all
Your feedback is what I assumed I would hear. I should have also asked if you all feel the PSB's would be good in a Home Theater application as well?

The PSB is the much better speaker over the B&W model in question as it should given it's price. We are loving the Synchrony's here in the showroom.
