No doubt the B&W 685s are one of the best bookshelves. I had these lovely ones with me for about an year before my upgrade. To get the best out of these speakers it has to be paired with a powerful amp (minimum 120 watts @ 8 ohms recommended per channel) for two reasons ... Sensitivity level (db) of these speakers & the Kevlar Mid/Bass driver.
An integrated amplifier like NAD C372 (150 watts @ 8 ohms per channel) will be a good match for the B&W 685s.

Ramesh,
I have seen Rotel is best matching amp for 685, Some models like Rotel Ra-04 or 06. But both are 45Wpc/60Wpc.
As per your recommendation, then we have to look for powerful than 100W.
How do you choose amp , based on speaker out or any other factor to be consider ?
