So I tried the E17 again, and found if I use the EQ (sacrilege I know) to boost the bass just a hair it made all the difference in the world, at least for a work setup. The AD2KXs sound really really good with this amp now. There are some recordings that have a bit of a "lo-fi" production that don't sound good at all, but in general everything sounds very nice to me. Very even, lots of detail, not too wide a soundstage so there is still enough of that in your face almost grado like quality.
Yeah they sound really amazing with a good bass boost, the E12 with bass boost on pairs really well with it too.
