$1,500 Amp budget - Best options?


I have narrowed my speaker search down to a set of B&W 803S or 803D.

Question. What are the best options to power these speakers with amp budget of around $1500? I'll be using my Marantz 5006 as the pre. Yes, I know there are some more expensive options that may offer a bit more quality, but this is what it is and I'm sticking to it. After I get my options, I'll try to audition as much as possible.

So far I'm considering a new Emotiva XPA-2 or used Bryston 4B-ST. What else do you'all think I should be looking at?

Thanks!

I was amazed at the sound of Odyssey Khartago Extreme SE on my fiends Dali MS4, amp was filling in for Thor tube mono blocks. And the Odyssey is even under your budget new.
Belles 150A Hot Rod. Steal at the price new; grand larceny if you find a used one. Sweet, tuneful and suddiciently powerful.
