Jim, I have been using a full blown (with all possible analog and digital inputs and outputs)TacT RCS 2.0 as both pre-amp and room correction for over a year. This unit has made quite a differnce in what I hear and how I listen. I, too, am "interested" in hearing the the RCS 2.0 as a room correction unit with a separate pre-amp. One reason for doing this is to "just check it out" and the second reason is because the RCS 2.0 does not have tape ins or outs. If you connect a record device (MiniDisc, CD recorder, etc.)to one of the outputs, you cannot adjust the listening level without affecting the recording level. Maybe TacT will issue an upgrade to solve this problem. Then again, maybe I am the only person who wants this feature. One final tought, Jim. If you try new cables, go through a room correction process and enter this set-up as one of the nine memories. You will then have different set-ups for the different systems you use (different cables create a different system). Give us an update again. What a great hobby!!
