I've done some comparisons, and do find that I generally prefer the DSD64 of the Norah Jones "Come Away With Me" version off my NAS over the MQA version that's based on that remaster. However, the caveat that I would put on there is upgrading components on the router does go long way in bridging that gap. Upgrading the power supply and the ethernet cables.
At the same time, I do prefer the MQA over non-MQA version over Tidal.
What I would like to do at some point is get a local MQA file and compare that to whatever highest res non MQA verison of the file.
