I've been dealing with a local guy who seems pretty knowledgable. He suggested I may be better off buying separate amp/pre-amp versus an integrated component as the sensitive electronics in the pre-amp would not be subjected to the heat generated by a separate amplifier. Another guy who works for the sister store 90 miles away told me by having separates you can introduce another variable by having the additional interconnect between amp and pre-amp and believed that an integrated amp was the way to go. By the way, I'm looking at Cambridge, Marantz, and Anthem components.
Also by the way, I listened to some System Audio 1750's at the sister store and compared them to the Monitor Audio GS8's. The SA's have an edge but the price tag is significantly more $2599 vs $1599.
