Above all what MQA represents for you, you need to assess what music means to you.
This is individual and can be divided in different components or priorities.
Music for me is about emotion, but i need technology to have it accessible in my home.
I do not listen to my audio equipment, i listen to music and need equipment to make it happen.
Nowadays, music listening or music delivery is done by digital means if not playing records (which i do not).
This digital delivery has hardware and software components and what we talking about now is software, the way the music is “coded” before delivery.
MQA is jet another format (is it?!) music is coded in and promises audio nirvana.
Is MQA disappointing? yes and no!
Why? Because the music, the recording is sometimes disappointing and sometimes it is not.
Sometimes recordings are remastered in “MQA format”, music that was great sounding and did not need MQA to be great, it was not meant to be recorded with MQA, MQA did not exist at the time.
New recordings with MQA can sound great, they where recorded with MQA in mind and have the MQA seal of authenticity.
But… a recording is what the musicians, the engineer, the producer want it to sound like, with some exceptions. There are records that need to sound raw and distorted, so MQA does only say that what i hear is authentic “noise” generated and packaged in a controlled environment.
Do i need to know that what is coming into my home is authentic?
Not for me, music is about emotion and i want to have the best music reproduction possible, a good recording is a good recording and is by definition authentic if handled correct from source to reproduction.
In the chain from my music provider, Tidal, i do not need processor greedy unfolding of MQA, it could just display; “This is Authentic”. Just give me the product, not the components, i have bandwidth enough to get it at home, 100% assembled.
MQA gives a guarantee that the music is authentic at the time coded digital information is converted to analogue, what happens after that is dependent on my and your equipment.
So how authentic is your equipment? And now we are here, how well equipped are you, are you all ears?
When i listen to music sometimes the display says MQA but more often not, and it always sounds great (not really but that is not the issue), why? Because it is the music i like and want to listen to.
TLDR; In my eyes MQA is a try to get a proprietary music format marketed, disguised as a quality seal of authenticity.
BTW: I have an MQA compatible amplifier and streamer.
