I'm looking for recommendations for a small hi-quality mixer for doing location work, and hoped to tap the vast experience of the group 8) I want something that isn't going to color my source feeds or add noise of any discernable level. All I need now is 4 channels, but I can of course live with 8. I already have a really nice Earthworks 2-channel mic pre, so the mixer would need good pre's for additional channels, all with pan capability. Any decent units out there that are very clean and transparent? Sorry if this is an overly simplistic request.... I'm just leery of equipment that will muck up the clarity of my source material. Cheers, Mike P.S. Anyone ever use the Benchmark MPS420?
