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!

@david_ten  When I am a voice of reason then that is not too comforting.

However, in my defense I do not have a good system yet, my KEF LS50 + Peachtree Nova 150 is a bedroom system. I am here weaving, bobbing, and talking the audio jive so I can buy a good system and be done with. I think I have 600 posts this year alone and 200 posts in the past 19 years (I had a different account name way back). Guilty as charged.
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.
