Does anyone have a Schiit Yggy DAC?

The Yggy is spec’d as consuming 35 watts (although a rear panel marking that can be seen in a photo at their website says 45 watts), and measuring 16" x 12" x 3.875" and weighing 25 pounds. 35 (or even 45) watts dissipated in a component of that size and weight should not result in the component getting anywhere close to being as hot as you describe. And the presence of numerous ventilation holes in the Yggy’s top panel further reinforces that conclusion.

Either the power consumption spec is drastically wrong or the unit is defective and what Schiit told you is wrong. Consistent with some of the previous responses I’m inclined to believe the latter.

Getting anyone at that company to speak with their customers is
not an easy task. They should have explained the product is a dual
purpose machine. Coffee warmer and sometimes DAC. 
I do credit them for truth in advertising.

Go to Home Depot (or Amazon) and get an IR thermometer.  Or use a “killawatt” to measure idle power consumption. 

My Modi 2 multi-bit is also a single-cup coffee warmer...

A note of clarification on the above idea that the Yggy's top holes are for ventilation.  They are actually not holes at all because they do not go all of the way through.  Same with my Bifrost and now Gungnir.  

There is no ventilation, so the warmth can add up.
