That piece leaves a lot to be desired in the area of clarity.
There is no attempt to make any mention of provenance with the disc sources, so if different source tapes or masterings were in play, then all bets are off with any comparisons anyway, not that one wouldn't like or prefer one or the other, just simply that it's not an apples-to-apples comparison unless the source and mastering are the same, with the only variable being the MQA encoding on that disc.
Additionally, he mentions then streaming these tracks from TIDAL, but does not say whether he streamed the 24-bit version, or the 16-bit version. In terms of the proper comparison of MQA-CD vs. TIDAL MQA streamed, it would need to be the 16-bit version in TIDAL and even then I'm not sure how one would know if the MQA-CD was the exact same source encoded or not. So again while one can certainly prefer one or the other, that doesn't mean conclusions can be made on an apples-to-apples basis.
Lastly, he states that "For the comparison, an MQA encoded DAC was used" and what he actually meant was an MQA decoder DAC was used, but he makes absolutely no mention at all of using an MQA-CD player, which are rare in the wild, but a requirement for decoding MQA-CD.
Without an MQA-CD player, that disc would be crippled to roughly 14-bit playback resolution, no minor detail. So stating a preference for the MQA-CD without ever mentioning it's properly decoded playback and on which disc player is... interesting to say the least. He also makes no mention of using an SACD player, so one is left to wonder if the Redbook layer of those discs is what was compared. Further, there are no SACD/MQA-CD players available, so any comparison made there is using two different machines, more or less voiding that comparison. The same can then be said for the TIDAL stream comparison, unless of course the SACDs had been ripped and the DAC in use was both MQA and DSD capable, otherwise he'd be playing the SACD from an SACD player, and the TIDAL stream from a DAC. Apples-to-oranges.
Again, he and everyone else are free to like what they like and state their preference, but when an article like that is void of so many important details, it's not very helpful at all in allowing anyone else to learn much from it. I certainly did not.
