Ya know, I have to admit that when I was listening yesterday, I had it on pass through (no crossfeed) for the first part and I thought that was the crossfeed. After I figured out (from a post here) I'm not sure what to make of it. It almost sounds like I'm switching to mono and removing some bass.
I just sent back a Total Airhead because to me it took away highs in crossfeed mode. Other than that, I really liked the crossfeed on the TA. It spread things out, with out moving everything forward, yet it combined both channels and made it sound like I was in a room listening (more than three channels, no more bass boom). With the MKII, well, I'm not sure what to make of it yet. I really like that the highs are perfect, I'm just trying to adjust to the forward position. It does take away bass boom and combines the channels as well, just seems to push eveything back together again, it's weird. Anyone else notice this?
I'm using an iPod > HD650s btw...
