How about a high quality but compact preamp like the Jeff Rowland Design Group Capri2? It’s 2.6”(H) x 13.7” (W) x 6.2” (D), has optional internal phono and dac boards, is fully balanced and and comes with an aluminum remote. Here’s a link:

Then just choose your class A monoblocks regardless of size, mount them on amp stands and position one behind or next to each speaker, connect each to your preamp with balanced xlr cables and run high quality speaker cables that are as short as possible from each amp to each speaker.
Ideally, it'd be wise to use fully balanced class A monos with balanced xlr inputs for optimum performance, but it's not required.
