just to update an old thread, if anyone is considering using this with a 2 channel preamp with full range stereo outputs, antimode is putting out a new unit. it will have stereo inputs and a few other nice tweaks for 2 channel systems. it will be out in november and cost $100 more than the current model which will still be offered. nice add, should have been done a long time ago IMO. see their site for the press release.
