Ralph,
I find the paring of the Contrasts with the ST-70 to be quite adequate in my 12'x15' acoustically treated room. Bass has improved with playing time. The Contrast are certainly revealing such that for my tastes best mated to warmish SS or tube amplification. It was their 16 ohm impedance that drew me toward the purchase.
Regarding the mono mode question: I am asking about your experience using two ST-70s as mono amps. I believe this is strapping. Based on the owners manual this can be done.
