Which amp to Nautilus 801?


I've ordered used B&W Nautilus 801 and I want to know if there is an integrated amp below $5k that will sounds quite fair with these speakers? Is there anybody having some experiences with that? I'm totally out of budget after this last purchase...

Hi
You will need at least 2*200 W / 8 Ohm in a reasonable-good room. In a bad room you will need 2*400 W.

I read that you can buy a Classe 2200 in the U.S. for 5k. You could upgrade later if you wanted more bass control.

There is currently a Musical Fidility KW500 integrated for sale on audiogon under integratedes solid state. The pre section is tube.
Any amp with less than 300W will not justify your purchase.They need lot of power and current to show what they are capable of.
Thanks
