Interesting indeed. Thanks for sharing.

I have yet to read where anyone that has listened to it thinks it makes things worse though  ??

No experience myself of course.... Just keeping an open mind.

I believe Paul McGowan and Ted Smith of PS Audio have written on their forum that they think it makes their DACS sound worse. You have to read Paul's comments with some eye towards him promoting his own products, but it is interesting to read a contrary review.

I was worried my DAC may not be "up-gradable" to MQA.  :lol:

After reading the article, I am comfortable again. I still long for higher resolution from Pandora and some streaming services However it appears I am in the minority. Few of the non audiophile population feel that way.

My 28 year old son (it tech a with degree and lots of certs) just looks at me like I'm crazy when I talk about high resolution digital audio.

I was able to listen to it for an hour or so about a year ago.  One of the reps was in a local shop and we listened on the top Meridian system in the store. It sounded very good. It really did, but I wouldn't say it blew me away.  I just wasn't familiar with the Meridian system I heard as I don't like them.

I don't think it was worse.

The claim is what John Darko found (ie its actually better than the original hi res files it came from):

What Paul McGowan found was while very close to the original it was slightly worse:
http://www.psaudio.com/pauls-posts/mqa-thoughts/

But even that is a good achievement.  Paul was told it could be better if it was optimized for the PS Audio DAC.

IMHO its the future of streaming services like Tidal.  Now I have a Tidal subscription I really don't buy new CD's or do downloads anymore except the occasional ones not in their library - but that's very rare.

The real issue with it IMHO is companies like PS Audio that constantly release new software updates don't want it because they will need to update the MQA decoder as well to get the best results.   We will see if it takes off enough so they will have no choice.  But even without it it sounds good - just not quite what is claimed.

Thanks

You might want to read this article about Pandora.

The article seems lucid, MQA looks another HDCD.

You can pontificate all day if you wish OR you could get Tidal (the demo is free), download and configure their desktop app and listen for yourselves on ANY DAC since the app has decoding up to 96/24 built in. Lots of people have written about MQA before they've heard it, which is too bad...

You are so correct.  It's typical of so many on the internet to talk about things they don't know about etc...  All too often folks look at graphs and measurements and make their minds up.  Folks forget how to listen.  I'm on the fence over the long term viability of MQA, just like I was about so many other formats of various listening and visual's before it.  Heck, I owned the Sony video format that was much better than VHS and fell through due to marketing, to laser disks to......name your tune.

I heard MQA as a dealer who had the rep in visiting with it about a year before they came to market with it and I was impressed.  I have and listen to a lot of high resolution music at home.  I find it's still all about how good or bad the recording is as nothing can compensate for that.  I heard fully unfolded files on an all Meridian system (not my favorite high end gear) and it sounded better than the same cuts in non MQA format that they played along side.  I will no doubt use it on my iPhone and through my AudioQuest Red, once that's available.  I have my QX5/20 from Ayre that won't have it available, but I will listen to the Tidal stream with and without to see if I want to use it on my main rig.  Again, I'm so glad it's available for some of their catalog and will be able to easily listen to cuts to see if I like it better or not. 

Too many folks get hung up on 48 vs 96 vs 192 and all the number in between.  Personally, I hear differences, but not huge at all.  I hear much larger differences going from 16 bits to 24 bits.  Adding more information seems to do much more for the musical experience in my system than the sampling rates.

Hi

Ok i appreciate the tip. I use tidal (hifi account) from ipad into my Yamaha receiver configured for multiroom use. However, I did what you said and downloaded it on to my gaming desktop. I got it and sounds good and tidal sounds good over my gaming headphones.  I am assuming i have it? The only thing is i can't compare it. Is there anyway i can turn this off or am i stuck with no comparison?

NVM, i get it now. Apparently with Tidal its by default. If you want to run different dacs solo with hi rez you need the paperwork. Thats what happens when you take a year off Hi Fi. You get out of the loop.  :lol:. Anyways i know what this MQA is doing. You can tell by any older recording with lots of dynamics. It sounds good but now its packaged and dynamics seem to exist at particular generic db level. IOWs they went ahead and turned up the db on all the music tracks... lol. They have gone ahead and made 70 dynamic music into 21st century loud music.... lol with a nice brand tint to it. Sounds like pleasant distortion actually. haha

I can actually replicate this MQA Brand sound with my Bryston BDA2. Well with out the dynamics loss of the MQA. It sounds like my bda 2 on an aluminum shelf a bunch of heavily shielded rca cable. I am trying to remember the braiding type. Definetly not your holographic cables Empircal use to sell. Dam i forget.. oh well who cares.

I don't mind it for my ceiling speakers using tidal. I am not sure how happy I would be about it in the sweet spot . I would likely turn it off.

I would disagree based on matched level A/B tests using my own original master files. If you had a Mytek Brooklyn you could turn the MQA processing on and off from your listening chair for some more tightly controlled listening comparisons that rely less on longterm aural "memory."

Well i would need to be able switch it off at the sweet spot to get a meaningful opinion.. How do you match level?

All I can say is that some of the conclusions reached in this article are not consistent with my admittedly limited experience with MQA.  I've listened to MQA files on Tidal.  My DAC does not natively support MQA.  Even so I found some of those files to sound very good.  So far I've restricted my listening to albums I've heard many times previously.  One of those that I found to sound better than its non-MQA version was the Crosby , Stills and Nash "Daylight Again" album.  To me it sounded smoother and less digital.  There were others for which this difference was less apparent or not apparent at all.  So far I haven't heard anything that sounds worse.  Just my experience.
