I Have the 82 setup and love it. I have not listened to the 52,62, or 35's.I assume you can't go wrong anywhere in the reference line. The bass on the 82's is great and almost doesn't need a sub in my opinion, unless you like to really shake the building or use it for HT use. I would go with a HK amp or seperates though, as I feel sometimes when I am cranking the system really loud it can get a tad bright. I think it's the Onkyo amp more than anything or that my room is all wood everywhere that might be at fault.
