The Yamaha A-S3200 would work for you. It supports 2 sets of speakers and has home theater pass through.
When I was looking at integrated amplifiers several years ago I looked at listened to the meager selection of amps that supported two sets of speakers. At that time, I listened to Rotel, Yamaha, and Cambridge Audio integrated amps. I ended up buying at Rotel 1590 on closeout. I still have it and I am happy with it. The Yamaha A-S3000 was the best sounding amp that I heard at but it was well beyond my price range. The A-S3200 is the current version the amp.
