Do you find crossfeed a useful feature?
Low gain matters because it basically detirmines the sensitivity and resolution of the volume control. You reduce the maximum volume in exchange for finer tuning of the volume. When you're using headphones like customs or most IEM's that have a low impedance, you want to use a low gain setting while high impedance headphones will want a high gain setting.
I don't still have my mkII. I used both it and my current 760 as a DAC/amp; I don't think I ever used the analog input once. The behavior of the device is identical regardless of input. There isn't a "line out" on either device; there's one output, and it's for your headphones. I think it would be an odd setup to use this headphones output as a line out for use in yet another amp, but to each his own, I guess.
I don't use crossfeed, but some people swear by it. For what it's worth, it does work well on the 760.
