Great review. I also own and love the DAC Magic Plus. Still at the end of the day I have to admit the amp section is just slightly lacking. Going to another amp by holding the volume switch pushed in while powering up goes into line out mode. You know you in line out as the volume knob becomes unresponsive. I have found even with super sensitive headphones, something like the Asgard One or even the little JDS Labs c421 portable amp gets me slightly better sound. Just a friendly suggestion, which may or may not improve with your headphones in use?
