I’m indifferent on MQA, but I don’t necessarily think it’s fair to judge it based on the output of a Bluesound product, just because the DAC there IMO really isn’t strong enough to get the full benefit of the hi-res music recorded under the MQA.
I’ve got a Powernode 2 (full MQA) and separately a Teac NT-505, also full MQA. The difference between the two is night and day, though granted one is a $2k product and one is $800. The Teac uses dual AK 4497 while the Bluesound uses (and the 2i versions also still use) a dated TI/Burr Brown lower quality DAC chips. Also, the analog output section of the Teac is far superior to the Bluesound.
For further context, I also have an Integra DTM-7 (full MQA), and again, like the Bluesound, it's DAC really isn't strong enough to unlock all of the goodness of Hi-Res via Tidal MQA, even though it's fully certified etc full MQA.
IMO it really doesn't make sense for MQA to be be licensing to lower quality DACs like Bluesound/Integra DTM-7 because the MQA hi-res experience will kinda necessarily be underwhelming with that level of DAC, and it's really nothing to do with MQA. (But of course not hard to figure out why they license to a high-volume company like Bluesound).
Tidal is my only source for all systems so I can’t really compare it’s hi-res content via MQA versus qobuz or hi-res downloads, fwiw.
All I’m saying is that were Bluesound my only reference for MQA, I’d be very underwhelmed, whereas with the Teac I am floored by the fantastic quality of Masters Tidal via MQA.
Bottom line, anyone looking for pheneomenal MQA/hi-res I'd suggest Teac NT-505 streamer/dac/preamp for $2k it's really really good. (also not knocking the cheaper products (I own them and like them for their modest cost) just not really suited to hi res MQA IMO).
