To moon,
The H/K 7000 has got grunt, it will give you a message, but mostly on the credit of the La scalas. The 8000 has a few more watts, I think 15 more per channel, that might get you 1 more db. It,s got 7.1, but I think thats about it. I'm very pleased with it, considering the cost of the 8000. $4000.00 Canadian. I got the 7000 about 6 months ago for $1600.00 Can. after digging. Takes a little getting used to for settings and stuff but quite happy with it. She's a little heavy "warping the platform it sits on",49lbs, but for the the price I don,t think you can beat it.
