I have my 970 paired to an Emotiva XPA-2 and XPA-5. I am totally happy with this combination. Based on owner reviews of the UPA-7, I don't think you would be dissapointed. It appears that you want to do a 7.1 setup, and in that case,I would totally disregard the Rotel if you are looking for a one amp solution. The Outlaw or the Emo would do just fine.
