Wanting separates but help needed .......

I have been pushing Focal 1037's with a Bat Integrated. I would like to upgrade to separates. I haven't a lot of knowledge as to were to go with today's amps / preamps. I have read a lot and tend to think that a Pass x250.5 and the new model 10 pre could be a good decision. Would McIntosh or others be a better choice? I'm in an area where you can't demo much ....... The rest of my system consists of:

EMM Labs - CDSA SE
2)JL Audio F113's
VPI SSMR
Aesthetix Rhea

Listening area is large - 32 x 40

Thank you in advance for the suggestions and guideance!
