I'm thinking that your lack of responses on each post are due to a lack of clarification on what you plan to use these for. What is your current setup and what are you planning on using this device to record? Got a DAW already? (If not, Reaper is a good, cheap option that's touted around here) I've never had any experience with any Sound Devices gear so I can not give any advice other than to give more information so that others on here know more about the particulars of what you plan to do.
