I've got an H/K 525. Reasons I didn't get that one:
1. It wasn't out when I purchased.
2. It's a Panasonic. Sorry, but I don't equate them with quality in audio equipment. I could easily be wrong, here.
3. It's ugly.
4. My reciever has 8 channel input and output.
5. Logic7.
6. Triple crossover.
7. Multiroom.
8. More than one coaxial digital input/output.
9. I don't know that thing's true output ratings (ie, not Manufacturer's claimed), but the H/K actually performs better (wattage-wise) than the manufacturer claims.
Essentially, it comes down to feature set. And I only paid $500 for it.
