It is going to take months to get a lot of music into Tidal. Also what software decoders are you talking about?
as of that day I was referring to Tidal's software decoder. I'm using a Mac, haven't tried Windows yet to see how that sounds yet although I do have a machine that I can install Windows 10 on.
Again Tidal does not have a software decoder. It is presenting the 24/96 MQA file which should be an improvement over 16/44. To get the info above 96khz you still feed an outboard decoder
but whatever it is it takes a LOT of CPU time compared to normal TIDAL/QOBUZ.
If I understand what was explained by Meridian a year or so ago at RMAF, they are sending a 'folded' file that contains 'Hi Rez' in a packet which is 24/48 and 'unfolding' it to something that looks a lot like the original Hi Rez file but without all 24 bits.
I think some of that is being done in TIDAL's new software as I am told that without decoding all you get is 16/44.1 and this version of TIDAL, when playing MQA with TIDAL setting the 'audio device' it sets MIDI Player to either 88.2K or 96K depending on the album.
Understanding TIDAL is limited to a packet size of 24/48 I am guessing that the 'unfolding' to 88.2K and/or 96K is going on inside my old/slow MacBook Air and is causing the fan to run full force after a few minutes.
Go to this link and play Meridians Stuarts video. it is a very good explanation of what is going on. It seems what he is saying is that the Tidal app by itself is taking the 24/48 file which contains region A with B and C embedded and Creates the 24/96 file which contains regions A and B with C embedded. To get C you need a dac with MQA decoding. That is why a dac without MQA decoding sounds better with a MQA file streamed from Tidal because you are getting A and B while a 16/44 file only gives you region A. I think I am finally getting it.
