Well, first congratulations for finding your way to your new home. The answer to your question is less than simple. The PMD 660 has phantom power, so conceivably could be used as a one-box system, but there are issues with the quality of the preamps in the unit. You may want to consider unloading the ART and the Denecke, and getting a decent preamp, which will greatly improve your overall sound. Search the Yard Sale, as Deneckes regularly come and go for an idea of prices. Then there is always fleabay. +T for moving up in the world.
