Recs for integrated amp with A/B speaker selector (750- 1,500k budget)

Hi,I am looking for the above with about 100w a side into a 8 ohms load. I will run two different pairs of speakers with it but never at the same time. I do not want to get an external speaker selector. Finding which quality integrated amps have a speaker selector is limiting and hard to figure. Rear pictures help obviously. Anyhow I figure someone here may have some good thoughts. 

Balanced input(s) would be a big plus but not a deal breaker. I thought the Cambridge Azur 851a was the ticket but while i have not heard one, user reviews are not great but it does have all the features I am looking for. 

Thanks in advance
