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 ones in stock. I'm torn, it's a lower rated unit (power wise). Should I go with the 430? Should I get something else? Any ideas appreciated!

BTW, I'm in a small/med room with VP150, 2 M22ti, 2 QS8s. Will I not care about those 5 watts? Is it worth it?
