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!

You don’t need to buy a preamp. The Luxman 509x can act as a preamp too. Check your manual for the setup.

You misunderstood. I was talking about if I were to purchase the m900 Amp. 
@thyname He was inferring that if you bought a m900u you can use the preamp section of the 509x standalone. You connect the 509x's XLR preamp output into the external m900u amp. There is a switch on the 509x that you likely need to flip.
I understand. But if I get the amp, I would prefer to sell the integrated to raise the cash
