Here's part of my post over at Audirvana's forum:

In interviews that MQA founder Bob Stuart gave to Computer Audiophile, The Absolute Sound and Stereophile, he said that encoded files could be "truncated" to 16-bit such that they would retain much of their benefit to a decoder over AirPlay. Two of the three reviewers for those publications actually tried 16/44 streamed files and reported that they were not as good as the 24-bit versions, but were authenticated at the DAC and sounded generally better than CD.

Obviously, the Red Book MQA CDs that are starting to appear would work with bit-perfect AirPlay. But I don't own any yet.

My question for A+ is whether or not this truncating process is possible within the program? In the meantime, I will attempt to identify the small number of 16/44 Master recordings available from TIDAL and play them to see what happens.

Now the answer from the A+ forum: While Bob Stuart seems able to deliver viable 16-bit files for decoded playback, others cannot. Damien (the developer) flatly states that MQA "can't be streamed without being truncated (and losing the useful MQA data) over Airplay".

Go figure.
