any significant differences between a Rotel 1055 and a 1056?
I believe these are the differences. The RSX-1056 adds: DTS 24/96, three component video inputs (instead of two in the -1055), three trigger outputs (again, as opposed to two in the -1055, and video upconversion (Rotel calls this "video transcoding"). It may have downcoversion also, but it doesn't specifically say this on the -1056 spec sheet. Amp specs remain the same. I think this is all, but I certainly could be mistaken.
