It all depends on what you do with yourself.   If I had the personal (quiet) freedom that someone so wealthy & aspects of privacy, even if officially quitting the 'firm', I would have resources to do all kinds of research projects.  If it isn't about 'research projects', it could be many other activities about personal growth and learning -- geesh, be the 100,000'th person to climb Everest... :-).


Again, it is all about how one takes advantage of the freedoms that they have.

IMO, rather than being sorry, you should be ashamed of such a sexist misogynistic opinion, worthy only of the most vicious English tabloids.

I know from experience that I'm too boring to spend that much time with myself...

I haven't seen the English tabloids -- I am not vicious, but a proper observation shows the SERIOUSLY DAMAGING AND DESTRUCTIVE INFLUENCE to be true.

 

Sorry for the distraction.

So in this review of the $10,500 (without storage) Grimm streamer, Atkinson insists, yet again, on interjecting MQA

where it has no place.  This paragraph-

 

.......could have been easily summed up with one sentance.."The MU1 offers no MQA support, and never will"....

 

Either Atkinson has no integrity, or he is obsessed with giving MQA as many mentions as he possibly can before he rides off into the sunset.  Pathetic, and sad. I would not buy a box of paperclips based on his recommendation.

This is not correct.

Music servers can contain software and/or hardware which can do DSP outside of Roon. In the MU1 this is an FPGA based upsampling PCIe soundcard with digital outputs, in our case it's our custom upsampling code running on a separate core, which uses Archimago's intermediate phase as one of the recipes.

So how do you support MQA when your own product also does upsampling outside of Roon?

If you want the Roon based music server to decode MQA, then just leave the core MQA decoder enabled in Roon for this zone, and the upsampling process can still be applied in another part of your server which Roon does not control. This process replaces the second unfold, so any attached MQA dac will no longer see the instructions for the second unfold. In essence, it no longer matters if you use an external MQA dac or not, MQA metadata will never be passed to the DAC.

If you want the Roon based music server to pass the MQA bitperfect to an external device which will fully decode MQA, disable the MQA core decoder in Roon and disable any further DSP in the music server product so that the metadata is being passed so that the MQA product recognizes it. Per design, you can truncate 24 bit to 16 bit or corrupt the bottom 8 bits and the blue light will still shine, but that's the only allowable transformation. You must leave at least 16 bits of an MQA file intact ;)
 



Then variations of both exist, where you would allow Roon to do the first unfold, and still disable any further processing in your product, and then any MQA DAC including the usually cheaper render-only MQA DAC's would do the upsampling step.

So Roon gives you a lot of choices

Good news. I had my first one a few weeks ago. Got some serious COVID symptoms after it but it seems that if you have had COVID the side effects are much worse after the vaccination. Was not nice to have them back again, but they passed.

Thank you for reading my review so thoroughly, Mr, Slapowitz. However, I am afraid I don't know enough about different kinds of  paperclips to be able to make a recommendation.

Years ago, when I still read Stereophile, I valued your testing of equipment specs. With your support of MQA, that is the only opinion of yours that I would put any credence in.

since you decided to waste your readers time with numerous gratuitous mentions of Master Quack Audio in a review of a $10,500 streamer, it is clear you don't know enough about modern digital audio either, Or you are knowingly ignorant.

 

Just admit you were wrong, and laid an egg with your endorsement of Master Quack. There is a small possibility it will save your legacy. Or not.

Just saw that. Imagine that.

It seems like a side-effect of Mytek separating themselves from their former manufacturing partner in Poland and the subsequent discontinuation of the entire product line produced by them.   It is only significant if Mytek has also deleted MQA from their new and current line of products.  I doubt it.

Wrong take. It is significant because of the lies told by the Master Quack society...that magical MQA mastering tools were around the corner, and that shiny new MQA encoding ADCs would be in every studio. The fact this product sunk like the titanic with no replacement means the market rejected it soundly.

 

Any recording, mixing, or mastering engineer who touts MQA would be laughed out of the room.

There is ONLY ONE way that I could accept MQA -- if  they get totally rid of FA.   I wouldn't mind 14 bits of clean audio with slightly lower SNR vs the 16bits of hash that most/many recordings are today.

That is still a major step backwards..MQA not only truncates bits, but adds aliasing and actually worsens "time domain" performance. There is zero benefit, and zero reason to ever accept it.
