I thought that, too, so when I set up my K-Line I put the KAT500 under the KPA500 on the desk. Then I saw the setup at Dayton, where they had the KPA500 with the KAT500 on top.

I asked the person at the booth and he told me that there is no problem running the amp with the tuner on top, that they are designed to have adequate cooling when installed in that position.

Hope this helps.
