I run the V3 primarily to get 8 channels in there by using the SPDIF input, then put my 'A-chain' mics through the V3 because, well it's there and it's great. I've run the same 'A-chain' mics in direct, and there isn't a huge difference in sound. I have little problem leaving the V3 home if I don't need 8 channels simply to cut down on size weight and batteries. Those running transformer pre's specifically for sonic color (instead of V2/3 transparency) may feel otherwise.
