I had the MQA guys, ROON guys, T+A guys, and Wilson guys in the same demo room showing people how good MQA was. They demoed with it on and off. My ears were a little ringing from a prior speaker demo in another room. So when I say I could not tell a difference on an uber expensive system with MQA on and off, there is a bit of uncertainty in that observation.
However, even at home with my DACs (including the Benchmark DAC3B) that both support MQA and do not, I cannot tell a difference either.
