It's really not that large. It fits in my jeans pocket and I am able to stealth it without too many problems. I love my D50 and can't imagine running anything else right now. The lack of a coaxial S/PDIF input may be an issue for you, however, if you want to run a V3 into it. The internal A/D sounds good to me, however, if a bit dark. I generally like darker sounds so I am fine with it. With your signal path, getting an Nbox or something similar into the D50 would appear to me to be an ideal low profile rig. Battery life is a major plus with the D50; you will never need to use an external battery pack under any circumstances.
