Mytek Brooklyn Dac plus running hot

What's in this little box that causes it to run so hot? Almost too hot to touch. To other owners Is this typical?

I've been tempted to open it up and see if something can be improved with heat sinks. Haven't yet though! I think it got a little better when I used an out-board DC power supply, which it supports.

Something in there gets pretty hot, and the air flow unfortunately isn't very good. The PC board itself obstructs most of the bottom to top air. Now I want to take it apart and see if it could use a carefully placed heat sink.
