Jeff Rowland Model 10 vs JR Model 1+Model 1

Please I very apprecciate any comments regards the decisio
to buy a JR Model 10 or another JR Model 1 to combine with my existing Model 1 and put in biamplifier.
My louspeeckers are PRO AC Studio 200 and the room size is around 26-27 sqm.
Thanks for any helps.
I've owned and compared both. The Model 10 is the better
of the 2. However I would use the Model 1 for continuity of the sound.
