Thanks for the news about the KAT500. But it says in the KPA500 Owner's Manual (yes, I do read manuals!):
"IMPORTANT: Provide at least 2 inches (5 cm) clearance behind the fan and above the amplifier for proper air flow."
This may hold true – to a lesser extent – for the K3...
How come the KAT500 is supposed to be put on top of them?
