Qobuz has hi res, that doesn't need MQA, I have both and on many similar albums, I prefer the Qobus over Tidal with MQA. But that starts the argument about library size and ease of interface, etc. But I also feel that MQA is worth the price of admission, moderate improvement over standard Tidal streaming on a very resolving system.
MQA?
On my digital side I have an Aurender W20 server with a Metrum pavane level III DAC. When I stream music I am using the HiFi TIDAL. The Metrum has an option of purchasing a card that I would install to add MQA capabilities. From what I have read there is some controversy as to whether MQA is a positive or negative to the sound of digital. I was interested in thoughts on whether I should add the module.
