2K is pretty good, You don't need to spend that much. I have the Focus 110 and have used them successfully with Naim Nait 5i and XS, only 50-60 watts. A very good powerful alternative is a NAD 375 integrated. I am currently using a Marantz PM 11S2 integrated, 100 watts/channel does fine.
If you got to have more power look at the Anthem 225 integrated. I have no experience, but have read much good stuff about it. 225 watts/channel.
All the above amps are well within budget.
