Tidal vs Hi Res Files vs CD vs “Netflix”. My test. Incredible!


1.     Introduction. I know there are several threads on different forums about similar subjects, but I couldn’t find one with the exact information I wanted, so I performed my own test.

This is not a scientific test, but I’ve got very consistent results that I want to share and read your opinions.

2.     First, the basics:

        2.1. I listen to ALL of my music streaming Tidal because I like very much its infinite library, the instant access to the music, the chance to make lists with different artists by gender and not having to listen to entire records, the cost of all that music against having a private library of CDs or Hi Res files, the interface, the information of the artists, the chance of finding new and amazing music, etc.

        2.2. If I decide to change Tidal (for CD for instance) it would have to be due to a SIGNIFICANT difference in sound quality.

        2.3. For the test I used the EXACT same system for every source, from the DAC to the speakers (pream, power amp cables, etc). By the way, the system is a hi end and a pretty revealing one, so I can hear the differences easily.

        2.4. I used only Tidal as HiFi streaming service as I don’t have Qobuz where I live (Argentina).

        2.5. For the comparisons I used the same songs in different formats and sources, most of the times (not always), from the same album when possible.

I know you will say that different masters from any band will differ in sound quality and I know that, but I’ve got consistent and very similar results on the different tests and if I have to choose a source with the effort of chasing each song’s perfect recording/master, it would be endless, pointless and very expensive.

        2.6. The songs I used are NOT audiophile grade recordings, BUT they serve for the purpose as they were available from the different sources and my CD collection is very scarce.

        2.7. I did only a few test as I don’t have the time and the patience to spend hours on this subject as I’m not a reviewer and, as I’ve said, the results were consistent.

       2.8. Cables (speaker, USB, RCA/Coaxial, Power, etc) are good enough, but not the most expensive ones (Kimber and DH Labs mostly).

       2.9. I did A/B test with almost no delay, as the three rigs tested were connected to different inputs of my DAC and I only had to switch between them. That helped me A LOT to detect the differences.

3. Rigs for the tests (upstream from the DAC)

       3.1. Computer-USB chain (for Tidal and Hi Res Files):

              Ethernet Cisco Gigabyte Switch and CAT8 Ethernet cable to my Windows 10 Notebook.

              Audinirvana+ for streaming Tidal or playing Hi Res files from the hard disk.

              Audioquest Jitterbug as pasive filter for the USB port.

              Wyred4Sound USB Reclocker with a Swagman Hifi Linear Power Supply.

              Gustard U16 USB to I2S converter (a very good upgrade in my system).

              I2S 2.1 protocol (HDMI) cable to the DAC.

      3.2. CD Player Rig:

             Samsung budget Blue-Ray player.

             Coaxial cable (Kimber 1m long) to my DAC.

       3.3. Netflix Rig:

              LG Smart Tv.

              Cheap Amazon Toslink/Optical cable to my DAC.

The Tv uses WiFi for connection, instead of Ethernet cable like the computer (wich is much better soundwise), and it is not connected to the AC Power conditioners and Filters as the USB-Computer chain is.

4.  Tests

      4.1. CD vs Tidal (Hi Fi and MQA)

          4.1.1.       Band: Huey Lewis and the News

                          Tidal (Hi Fi and MQA) Album: Sports.

                          CD Album: The Best of Huey Lewis.

                          Best sound in order:

                          a.       Tidal MQA

                          b.     CD

                          c.       Tidal HiFi

NOTE: the differences/gaps in sound quality between a; b and c were similar. NOT big, but noticeable and “very consistent with the next tests (A-ha and Coldplay)”. I also think I noticed them as I changed fast from one source to the next. Otherway, I think it would be hard to detect them.

           4.1.2.       Band: A-ha

                           Tidal (MQA) Album: Time and Again, The ultimate A-ha.

                           CD and Tidal (Hi Fi) Album: The Hits of A-ha (not available on MQA).

                           Best sound in order:

                           a.       Tidal MQA

                           b.     CD

                           c.       Tidal HiFi

           4.1.3.       Band: Coldplay

                           Tidal (HiFi and MQA) Album: A head full of dreams.

                           CD Album: A head full of dreams.

                           Best sound in order:

                           a.   Tidal MQA

                           b.   CD

                           c.     Tidal HiFi

      4.2. Hi Res (PCM 96/24) vs Tidal (only Hi Fi, not MQA)

           4.2.1.       Band: Pink Floyd.

                           Album (for both sources): The Division Bell.

HiRes file was a LITTLE better. May be so little that it could be placebo effect and so little that it doesn’t justify having HiRes files for computer playback.

     4.3. Netflix vs Tidal (Hifi)

Here I don’t have many choices as Netflix is not an audio streaming app.

I found the difference by chance. Nevertheless, before the tests, I always had the feeling that the sound coming from Netflix was somehow better than my USB rig, but I thought it wasn’t possible and it was only my imagination considering all the money I spent on my USB-Computer rig. BOY, I WAS WRONG!!

I only compared a couple of songs, but I didn’t need more than that a couple of direct comparison as I find ALL of the songs to sound better than my USB rig because I’ve been listening to the latter for a long time and, eventhough every recording is different, I know how it sounds my Rig in general (tone, soundstage, layering, imagining, impact, bass, etc).

The songs I used to make the A/B comparison are “Still falling for you” from Ellie Goulding from Bridget Jones’s baby Soundtrack and “Nothing’s gonna hurt you baby” from Cigarettes After Sex from Kidnapping Stella Soundtrack.

Well, eventhough they are NOT audiophile songs, the sound from my Tv (I repeat with wifi, cheap cable and NO AC conditioning) is SO MUCH better and analog than the one from my USB rig, that I still cannot believe it!!!

I cannot compare it to any other format than Tidal HiFi, but the difference is SO BIG that I think not even Tidal MQA on my USB-Computer rig comes close.

5.       Conclusions

      5.1. I know that if I get a better CD player I will get much better sound, but I also think that if I get a good streamer-transport, I will also improve my Tidal sound quality a lot, may be by a similar margin.

      5.2. So, Im after a good streamer-transport to get AT LEAST the sound quality I have with my Netflix rig. If I dont get it with it, I will recomend Tidal to hire Netflix engineers!!! J

6.       I would love to hear some other audiophiles “similar” experiences with CD vs Tidal vs other hifi digital formats and sources.

Please only post about real experiences, not getting to technical, as it gets boring and somehow useless.

One potential problem: no classical music, perhaps weighting the results in one direction or another.
I think there is some merit to the shorter signal path argument.  You have a lot of pieces in your computer to DAC chain, even though your additions were designed to improve the USB signal from the computer.  Also, optical connections like that from your tv are supposedly "quieter," because they are not subject to electrical or radio interference.

Computers are a noisy source.  I purchased a LUMIN U1 mini as a streamer and it breathed new life into my DAC.  The noise level decreased noticeably.  My Mac Mini and the LUMIN unit are connected to the same inexpensive D-Link Ethernet switch, but I changed the power supply on the switch to an iFi unit.  The LUMIN sends a much quieter signal to my DAC and the result is more clarity and detail in the music I hear.

One question - Is your computer connected to a wall outlet when you listen, or not?  If the former, I suggest you do an A/B test of the computer running each way.  Some have reported better signal quality running with the computer unconnected to an outlet.

Good luck and happy listening. 


I currently use a Sonore UltraRendu with a CIAudio LPS feeding a Mytek Brooklyn+ DAC from Roon and Tidal in one system, a Roon Nucleus feeding a PS Audio Directstream DAC in another system and a Roon Rock i7 NUC that I built just feeding a Yamaha RX-A1060 in the HT system. All three sound great, but if you don’t use Roon then the UltraRendu is a great option. I have been moving the Nucleus and UltraRendu back and forth between the systems to decide which I prefer, but honestly I don’t hear a difference.  Good luck in your hunt!
Hello guys, thanks for the response. 

@sameyers1. Yes, I've tried running the Notebook with only its battery and I dont hear any noticeable difference. I will try again just to be sure.
On the other hand, if I connect the USB output of my Notebook directly to my DAC, the sound is much worse. Both, the W4S USB Reclocker (RUR) and the Gustard U16, do a GREAT job, mostly the latter, but it aint enough to match the quality sound of my TV rig, wich has no signal or AC power conditioning whatsoever.
Just to mention, if Im not mistaken, John Darko on his review of THE RUR said that he couldnt hear a difference in sound between a computer with the RUR vs a budget streamer. Well, I dont think so. Eventhough the RUR does improve the quality sound of my Notebook USB signal, and eventhough it has an audiophile Linear Power Supply and then the signal goes through the Gustard U16 (wich helps A LOT), its not enough yet. 
You just said it, Lumin U1 Mini gave you the best sound as it's an audiophile dedicated streamer/transporter. I think thats the way to go.

@hrabieh. My DAC is the Audio-gd R8 Ladder DAC, with upgrade of Accusilicon clocks. I've been told from some experienced audiophiles that its a hell of a DAC, competing with ones costing much more.

@markcdaniels. Ultra Rendu is another options Im evaluating. I bet it sounds great!
