Good desktop amp/dac/with phono stage for Harbeth P3ESR?

[Blake Klondike]

Just got a pair of P3ESR monitors that I want to use for listening and for reference vs. my Genelecs when mixing. I am looking for a small desktop amp with phono stage and DAC, and some way to switch between both speakers. Does something like this exist, or will I have to build a stack of some kind? Desk is pretty pressed for space, so would like something small, but want to do the speakers justice. Any kind of configuration is fine, so long as it does the job well and is compact. Thanks!
