For grins, I just tried an Epiphany on my APL-3910 in place of my Elrod Sig 2 - I was astonished at the difference. Much better dynamics and more detail as well as slightly better imaging. It was almost as though a "veil" had been lifted. Sound seems a little more forward, as opposed to laid back with the Sig2, but that's not a bad thing.
The 3910 also appears to be happier.
