How's the Synergy between Lamm1.2ref and AR REF5

I am in the process of building a system around Wilson Sasha's and have narrowed my electronics down to either Lamm (1.2 Reference monoblocks/L2Reference pre) or Audio Research (REF 210/REF5).

Both sound great to me, but i have a couple of issues with going all Lamm (lack of remote) or all AR (tube hassle/cost with REF 210).

Thus, I am wondering how the synergy is between the combination of the Lamm 1.2R with the AR REF5?

Is anybody running this combo?

Thanks
