Interesting that the reviewer comments more than once upon the tonality of the amp where classical as the genre is concerned.
Whilst I was considering whether to stay with ARC amplification, or go with D'Ag Momentum, during an A-B demonstration of the two it was the organic way the ARC portrayed stringed instruments that opened up a clear lead for me , in particular on the day Pierre Fournier's recording of JS Bach 6 Suites for Solo Violoncello BMV 1007-1010.
