When I was in the market to try streaming, I bought a Mytek Brooklyn Bridge because it came with MQA capability. I gave the process a fair shot and, yes, it did improve sound quality a bit over Tidal's bread-and-butter streaming. The trouble was that Qobuz, without MQA, gave me better fidelity than Tidal whether Tidal was MQA-ing or not. Long story short -- I dropped Tidal and have never given MQA another thought.
