I thought this was interesting. A review of MQA-CD by the not-very-techy Techmoan. Interesting that in Japan some MQA-CDs were released with regular CDs in the box as well, to give the listener a way of comparing the two.
The potential snag is that the 'regular' CD may not be exactly the same up to 22kHz as what was fed into the MQA encoder. Some of the 2L examples that are the 'not MQA' versions are low pass filtered, for example. The MQA ones show what renders as 'noise' on a simple power spectrum in that region if you have no other way to deal with it.
So although you can compare, the *reason* for any 'difference' may not be what it seems on the surface.
