I think using a B&W 600 will give you more details, of course they're more expensive as compared with the diamonds. I use a NAD receiver and Wharfedale D 8. It's good for movies, as for music, I'm wanting for more details and highs. I think the NAD is best paired with KLIPSCH or a MISSION speakers, maybe also good with B&W.
Just my 2 cents.
