When I stack the DAC-100 on top of the HAP-100, then they feel like they're roughly the same temperature.
Wow.. 10W idling current? That's pretty deep into class A considering the headphone output is rated for 500mW. I wonder what the idling current for the HAP-100 is.
Have you tried rolling opamps yet?
