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.

Hello @dtximages

I'm not streaming music from Netflix, I've just compared some two songs you can hear from a couple of movies on Netflix vs the same songs on the Soundrtrack albums from Tidal.


Ohhh ok.  Yeah that's total apples to oranges.  The movie will EQ the crap out of the music so you might as well turn the bass and treble knobs all the way to the right basically.

Chromecast Audio vs. MSI Laptop
I ran a small test of my own this weekend to try to compare an MSI laptop against the Chromecast audio. My setup is KEF Q150s, on Monoprice Monolith stands, crossed over well with a sub, all powered by the Peachtree Decco65.

The MSI laptop connected to the DAC in the Peachtree Decco65 via USB. The Chromecast connected to the DAC in the Decco65 via toslink. This made for easy switching. The USB cable was stock. The toslink was an AudioQuest Forest. I streamed Tidal CD quality in both cases. I can’t say I heard a difference between the CCA or laptop.

However, I did notice a difference between CD quality and MQA. I could hear more background information in Joshua Redman’s City Folk. Very obvious difference, and almost as big of a difference as going from MP3 to CD quality. Unfortunately, neither the CCA nor the DAC in the Decco65 can decode MQA. And because I listen in my living room on the couch through the convenient CCA, I’ll be limited to CD quality as I stream. If Tidal included the ability to use a laptop as an endpoint the way Spotify does, I might consider using the laptop as dedicated streamer.

Digital streaming reviewers John Darko and Hans Beekhuyzen often talk about the differences between wifi and ethernet connections on individual streamers. They both say that although bits are bits, wifi implementation is the real issue. Wifi is apparently very electrically noisy. HiFi manufacturers focus on eliminating noise in their components, with some of the biggest culprits being the power supply and wifi. Although I do not have access to higher quality streamers (and I’m still coming around to the idea that I might benefit from spending more than 100USD on a device that merely streams), I can talk to my experience with the CCA.

The biggest gains for using ethernet with the CCA come when using the CCA as both the streamer and DAC. By running toslink out of the CCA, I offloaded DAC duties to the Decco65. At that point, both wifi and ethernet options sounded very similar. However, I do believe I hear a difference that justifies running an ethernet cable across the room. First, I would point to the Yellowjackets’ Man Facing North. The bass fingering around 1:00 to 1:10 sounds clearer. Second, I would point to the fact that I respond differently emotionally to the track. With ethernet, the drum solo at the beginning convincingly sounds like I’m physically present, but over wifi the solo doesn’t sound like I’m in the same room but like I’m listening to a great recording.

In sum, I would consider the CCA ethernet adapter the smallest improvement I’ve experimented with so far. Speakers, speaker stand, sub, integrated amp, and DAC, made the biggest improvements (in that order).
Hey @classdstreamer
Very good and interesting info.

I've got similar results using Ethernet vs WiFi, not big difference, but noticeable. 

I also think that using a better streamer, not too expensive, like Bluesound, will give you another significant upgrade, as it will do adding some USB conditioner on the USB path from your Laptop to the DAC.

I just bought the SOtM SMS-200 Ultra Neo Special Edition and I will take it home at the end of september. Just then I will be able to know how big the difference are between a computer USB signal (very well processed) vs a very good streamer. I cant wait!!  :-)

There´s a neverending upgrade path in front of us!!  I think I want to take a rest after this new upgrade... I hope!
