I also use ASR electronics: Emitter II and Basis Exclusive.
The Basis Exclusive has actually two independent phono-pres
with RCA and XLR connectors by each and MC and MM inputs.
So you can use two balanced and two unbalanced tonearms
but you will need to switch for either kind in the inside
of the pre.
For my other TT and tonearm in my second system I bought
the Jasmine LP 2 phono-stage. There is a new model with
2 connectors for two tonearms.Not in the Basis league but
very good. The price is about $600. This is in my case a
more practical solution for the third tonearm.
