For me, the decision wound up being made by my choice of DAC (I use Tidal). I fell in love with the Benchmark DAC3 (no MQA) - the improvement in sound was just amazing. Figured that difference in DAC was larger than the difference in MQA, so went with a good DAC that lacked MQA support
Just an explanation of the path I took and my own finding that the DAC made more difference for me than MQA (and Benchmark readily supports Hi-Rez downloads for music that I particularly enjoy - digital equivalent of buying LPs just for particularly beloved music. Perhaps if I had better ears or more expensive equipment I’d have a finer point of view on MQA vs redbook stream)
