"Only heard MQA/non MQA a/b demoed one time. Constellation electronics driving Magico speakers. To my ears, there was a slight preference for the MQA. JMO"
No public demo has been done comparing an MQA track played through an MQA dac with a non-MQA hires version of the same track played through a non-MQA dac.
Such a comparison if done will eliminate completely the potential of MQA code in a single dac unit to mess up non-MQA files, as pointed out by JA at Stereophile.
This messing with a non-MQA file will result in an MQA file always sounding better than a non-MQA file from the single unit MQA dac.
