I do not have a Concerto, but do have the Coherence II in my main system. It replaced a Hovland, which it trounced in all ways except for midrange bloom (the Hovland is more colored). The Hovland was also noisy due to its unshielded outputs.
I do not know how the Concerto compares to a Coherence II, but my guess is that it has a similar sound (neutral-ish), with the Coherence being more refined.
Hope this helps.
