very impressive sound due to the excellent combination and good recording you did; my ears are thankfull and could make the difference with others amp Denon, Marantz, Nad, etc.. with my Emit 20 (the best shellbook for the price) I have an Amp NAD C375 (very analitic and neutral too) but it's lack spaciality i can't feel the difference range of instruments, so like the hegel 160 (and certainly H90 and Rost) can do.. I hope to by one of these amp. You convainced me.
