I'm not Andy (obviously) but I can speak to stacking - I keep the (warm running) iDAC-6 on top of the iHA-6 all the time. It's fine, the amp gets warm but not hot. And this is with the very hot iDAC-6 on top, so I imagine most any other device stacked on there also would be fine. By the way, the signup for US Review Tour is almost closing. Get your "application" in if you haven't already done so. I warn you though, be ready to buy it once you experience it for yourself!
