Tidal ‘HiFi’ is NOT lossless

TLDR: Tidal ‘HiFi’ is not lossless. It just streams the MQA version of tracks with some metadata removed to prevent most DACs from recognising it as MQA and limits streaming to 16 bit.

A while ago I posted a video which discussed how MQA was not lossless, and additionally, how there was actually no way to stream the lossless version of any track on TIDAL that was marked with the ‘MASTER’ label, even if you had all settings configured not to use MQA.

Example of a track tagged as ‘MASTER’ on TIDAL.

The issue was that depending on your settings, one of a few things happened:

– ‘MASTER’ quality setting – Track streamed in MQA. Tidal client or your DAC can do the unfolding depending on setup. MQA is not lossless.
– ‘HiFi’ quality setting – Track streamed in what was claimed to be ‘lossless’, but it was actually seemingly just the MQA version without any MQA flagging or metadata, so it would not be unfolded. And is also not lossless.
– ‘High/Normal’ – Track streamed in compressed format.

If you want some info on why MQA itself is not lossless and probably should be avoided, watch this video:

However, recently TIDAL has released a new pricing structure, and you can now opt to pay half as much as the MQA ‘Hifi plus’ tier and not have MQA.

You will have access to the ‘HiFi’ tier which TIDAL still claims is lossless.

I wanted to find out if along with this new pricing structure, TIDAL had put back lossless versions of tracks, or if it was still the same ‘hidden MQA’ versions.

To check this you can either rip the file from TIDAL (I will not mention any software as I do not condone piracy), or you can record the bit-perfect audio stream using a tool such as VB-Hifi cable and recording software such as Adobe Audition. Then compare the files using a tool such as DeltaWave.

So, let’s take a mainstream track, and compare the lossless version that is available on Qobuz, Deezer, and Amazon HD, to the version on TIDAL.
Starting with a track that is NOT marked as ‘master’, I used “Save me from myself” by Louis the Child.

Comparing the TIDAL version, and the Qobuz version using the DeltaWave software, we can see that they are bit for bit identical. No difference whatsoever.
Meaning for tracks WITHOUT the ‘MASTER’ tag, Tidal does deliver lossless files as long as the one provided by the artist/label was lossless in the first place.

Deltawave comparison of the Tidal and Qobuz versions of the track. As shown in the bottom left, they are a bit-perfect match. Identical/lossless.

But, what about tracks that DO have the master tag? As those were the ones that were troublesome in previous testing.
For these tests I used Louis the Child’s ‘We all have dreams’. I chose the version from the explicit-deluxe version of the album just in case the different album versions had different masters.
The very first thing to check is if ‘hifi’ serves 24 bit files for tracks that have a 24 bit master.

In Roon, logging into my Hifi Plus account and selecting the master tier meant that the track streamed in 24 bit, whereas on my ‘hifi’ account it streamed in 16 bit.
(This can also be verified by recording the digital output on a 24 bit virtual cable and checking if any of the last 8 bits have any content but it’s easier to show this way).

This is a bit concerning, as the track itself IS a 24 bit master, and on other services such as Qobuz or Amazon HD, it is in 24 bit.

This means that right off the bat we can say that the Tidal ‘hifi’ tier isn’t lossless for tracks which have a 24 bit source file. It seemingly restricts you to 16 bit.

Let’s check what happens on a track that was from a 16 bit master.
For this, I used ‘Adderall’ by Max Frost as the source file is 16 bit 44.1khz, it’s available in 16 bit on Qobuz and other services, and it is available in ‘MASTER’ quality on TIDAL.
There are a LOT of tracks on TIDAL that are available in MQA even though there was never a high-samplerate master in the first place.

Comparing the Qobuz version to the Tidal ‘Hifi’ version:

NOT a bitperfect match, and there is quite a bit less high-frequency noise on the Qobuz version as indicated by the pink regions. This is consistent with my previous testing on MQA files which showed that there is added noise in MQA versions of tracks.
However the Amazon HD, Deezer, and Qobuz versions all matched with eachother.

This result was the same for all other tracks I tested. In each case, other streaming services would match bitperfect, but Tidal would have a file that did not match and was not lossless.
This means that unfortunately as it was before, TIDAL does NOT stream lossless files for any track that carries the ‘MASTER’ badge, regardless of your settings or subscription tier. You can ONLY stream lossless on tracks which do not have an MQA version at all.

Additionally, we can see that there is still some MQA data present in the ‘HiFi’ version as Roon picks it up as an MQA version:

The ‘HiFi’ version is seemingly just the MQA version, but limited to 16 bit and with some (but seemingly not all) MQA flagging/metadata removed.

If you want to stream lossless, other services such as Qobuz and Amazon HD are better choices.

  1. Great review! I really appreciate someone like you taking the extra steps and showing us what we’re really getting out of those services.

    • Thanks!
      I’ll be doing a video comparing the various options once spotify hifi is out. Unfortunately there is no one ‘best at everything’ option currently as they all have drawbacks. But I think it’d be a good video

      • I’m extremely excited about this, as I feel as though I notice audible differences in AMHD and Qobuz. My wallet wishes I didn’t.

        Hope we don’t have to wait on Spotify HiFi much longer. It’s starting to feel like they’ve backed out.

    • If the last 8 bits are all 0, that means that there is no content there.
      You can store 16 bit info in a 24 bit file by just making the last 8 bits all be 0.

      Tools such as MediaInfo will tell you the true bit-depth of an audio file

      • I’ll have to check out MediaInfo. Will opening up an audio file in TexEdit or similar array the file in its 16 or 24 bits to show if the final bits are zero?

  2. I have no specific knowledge regarding MQA or Tidal. Still I do know from my many years in business that it’s a common practice for companies to hire firms that specialize in discrediting, discouraging, and disparaging anyone who effectively exposes information they deem objectionable. At first, they might not have seen you coming, but it’s entirely possible that by now, they have a plan and team in place. At least this was my first reaction when I saw the last two reply’s that seem unusually snarky and out of place given your calm, objective, and remarkably restrained approach. Do NOT let this “noise” keep you from doing the important work of reminding decision makers that claims made that can be tested will be tested.

    • Some are professional disgracers. My thoughts go to those who paid the subscriptions, bought the expensive “origami rendering” gear only to learn that its BS. I would be in denial too..

  3. Thanks a bunch. I used to use Amazon HD and it was a great value for the whole family, but the lack of Roon integration and the fact that it didn’t support and respond to my DAC made me move away to Apple Music for general streaming and Qobuz for integration with Roon and for serious listening.

  4. I would love to see an analysis of apple music sometime, and their lossless tier. It sounds identical to Amazon HD to me, but a proper test would be very cool!

  5. I have an RME dac and the complimenting Digicheck software shows true bitdepth. Tested some “hires” files ive bought. Supposedly 24 bit files are 16 bit audio plus 8 bits of nothing. This shit is nothing short of fraud. About fraud, Tidal has a history of it. Kanye, jay-z and Beyonce manipulating their streaming numbers, and now this MQA hassle. An applause to Goldenboy here who exposes it!!!

      • A corporate culture established by founders almost always persists long after they exit. Every M&A acquisitions professional and acquiring entity/investor understands this and a very big part of any acquisition strategy is to determine; do you want to change the culture and if you do, will you be able to (which most often the determination is that you can’t).

  6. Tidal has a store where you can buy music, both in mp3 and flac (https://store.tidal.com)

    I assume your tests/conclusions were against the streaming version of tidal, not the downloadstore?

    Do you know if the flac versions of the download store are also affected

  7. Even before Tidal introduced MQA, they have been using very lossy algorithms for their streaming service. It has always sounded completely inferior to Qobuz, and even also inferior to a normal cd. I knew friends who paid for Tidal’s so-called HD streaming, and they didn’t seem to hear how dry, lifeless, constrained the music sounded. Even when just switching to a cd, you could immediately hear how all the ambience and the lower end was gone in their streaming output. Tidal is for deaf people…

  8. Thanks for this review. As someone interested in subscribing to Tidal, such information is neither pathetic nor tiring – I appreciate knowing what I’ll get for my money. It’s is unfortunate Tidal themselves do not provide this information but continue to mislead. Keep up the good work.

    • Same here, I really appreciate knowing what’s going on with a product I can barely afford.
      MQA was bad, but don’t mess with my lossless!
      I have unsubscribed from Tidal.
      Thank you Goldensound.

  9. Thanks for the work you are doing. Since Apple Music is sending AAC 256 over Airplay 2, Deezer via Chromecast is the only option for me for lossless audio in my country until spotify hifi is out.

    Could you please post a comparison graph for Qobuz vs Deezer? I am asking because people on ASR showed that Deezer had less energy in high frequencies due to slower filter. Is this true?


  10. Just to double check, did you end up logging in both HiFi and HiFi Plus for the Adderral track? In HiFi Plus, if you perform all the unfolding, do you then get back the 16 bit file found on Qobuz, Amazon, etc?

    Appreciate the hardwork, just wondering what conclusion to draw.

  11. Thanks for this Golden One. I have been running both Tidal and Qobuz subscriptions for a while, mainly because Tidal makes the most current music more accessible and the interface in Roon is better. I had hoped to drop to a hifi subscription to save a bit of money and still get lossless but seems this is not the case, which is disappointing, but at least I now know.
