I'm looking for a preamp, something I can use live w/a Crown C1000 as well as in the studio. I have the software version of the SansAmp PSA-1, and I am pretty impressed by its wide range of tones. That's not my most desired feature in a pre, though, and am not in a position where I can go out and try out stuff (none of the stores here in the ATL have pre-amps like this in stock). Most important for me is tone (want great lows and transparent highs). I also want something where I can choose between pre- and post- on the output to the house/board. Why spend all that $$$ when all you have is basically a direct box? So my question is...is the Aguilar DB659 worth the extra $600? I could by 3 SansAmp RBIs for that. The Demeter gets good reviews, but is pretty expensive too (2x the price of the RBI). Do they really sound that much better? What about features?
