I currently have a very cheap set of Infinity all-in-one HT speakers and a DSL Sub and want to upgrade at a minimum the fronts and center to go with my new HK 525. Budget around $1000 +/-. The problem I have found, is that most of the better speakers that I may audition, are being driven by Denon, Yama, Pio, etc., not HK. So I was wondering what everyone else is using with their HK receivers? Thanks.
