The splitter snake I plan to use next time around is transformer isolated
on each channel with switchable ground lifts.

This is another part of the whole package I'm still settling on.

At this point I'm leaning toward RME gear, but it's not set in stone yet.

I'm also working on that. I'm trying to strike the right balance between
building in what I want/need and keeping it man-portable. I looked at
some shockmount racks on caster plates and the weight for the rack alone
was typically 75-100 pounds. Throw in the computer, its guts, outboard
gear, UPS, etc, and the weight adds up very quickly.

Excellent - lots of stuff to chew on. Thanks for the detailed response!
