Luxman L-509x for B&W 803 D3

I recently acquired a pair of Bowers & Wilkins 803 D3 speakers. My integrated Amp is currently Luxman L-509x rated 120 WPC at 8 Ohms and 220 WPC at 4 Ohms. Class A/B, but Class A biased for the first few Watts.

Is my integrated amp good enough for my 803 D3, or do they need more power? I have read / heard the 800 series B&W need gobbles of power to shine.

Thanks!
