Sorry if I'm not giving you enough info all at once, this is not my forte. My Onkyo is model Tx-NR646, the one in the other room is older and has few bells and whistles. Where the TX is, in terms of volume will have to do. I see now that if I bypassed the receiver in the other room I would go with one set of cables directly in to the DCM speakers. However I use the speaker and the receiver for other things and would like to be able to play different things in each of the rooms, if possible by choosing the zone. Hmm...not sure that's workable. I've enclosed a pic of the connectors I may have to use, two of these per each speaker. So one set would go to the old receiver and one to the receiver from the main room. Not sure I really understand bi-amping but the article was interesting. I know I guaged the wire for the distance which will be about 50 feet. From what I read the difference in sound would really not be noticed.
