My new HK 525 sparked and smoked. It's totally toast! Anyway, one call will replace it with a 430 if I wish. They don't have any other 525s in stock. I'm torn, the 430 is a lower rated unit (power wise). Should I go with it as a replacement? Should I get something else? Any ideas appreciated! BTW I have Axiom VP150, M22tis, and QS8s in a medium sized room.
