I can't possibly imagine that the mini dsp would not be a great little device, being so completely simple to program. USB integration....
Do you have a measurement system in place... REW ?
I have yet to ever get REW implemented properly for myself, my buddy (Nuance) always came over to help me with his rig.. but I'm going to be picking up the Dayton OmniMic System, Simple - USB Mic and software, no preamps or calibrating necessary..... should be avail on the 12th of Jan....
Some good Discussion on it over at AVS...
