Yeh, he's one of the good ones. His final comments on MQA didn't seem quite accurate though, i.e. he forgot to mention that the supersonic content is lossily compressed.
That may not matter (supersonics not reproduced accurately) that much as you can't hear it anyway ?
As Waldrep states most recordings don't even need/reach 11 bits accuracy the bit reduction (when coming from 24 bit masters) may not be as problematic.
What I find interesting is that Waldrep leaves a small door open and said that you can't hear differences between hires (sorry master quality) and CD and that nobody really can.
BUT he found he did not suffer from listening fatigue when working all day listening/working with hires but is exhausted after fiddeling all day with 'normal resolution' recordings.
This coincides with things most audiophiles claim as well. That it is 'easier' to listen to, less strained.
