Your speakers will always have good resale value, as the woofers alone, new cost over $500 each, and may not even be made anymore.
As for you question about power:
The bigger B&W speakers love a lot of power! The more the better. I use 600 watts per channel with B&W speakers that are 93db/watt and are 4 ohms. They also like SS, especially for bass control.
