I've been in Recording and Pro Audio for about 25 years and have listened to a lot of DSD. It's great. So is PCM. I have never once listened to something and said "Ohhh, I wish this was in DSD!!!" Never. Not once. I never even think about DSD unless someone tells me "it is DSD". It simply does not make an impactful difference to enjoying music. You are likely to hear a bigger difference if you have extra pillows on one side of your couch that the other, or a rug vs. carpet. or even a cold dry day vs. a hot humid day.

[@anadialog]

In fact it doesn't make any sense. In terms or recording, playback environment is important but a separate problem, you must simply do the best you can with the best equipment. Analog tape is by far the most engaging but native DSD has its emotion. Let's just leave aside conversions and enjoy the original recording format. Can't go wrong!

DSD got a wide introduction 5 years ago. First, I was really skeptical, especially knowing it came from Sony. But then, I started working on DSD decoding and listen to a lot DSD samples. And then I realized how good it is sounding. Now I collect almost only DSD.

[@sammcrae8892]

But, what about the Evel Sony being involved? I'd actually like to know, as most of my stuff is Sony. I've usually been fairly happy with the quality of their products, although, it does seem that they have been playing to the low end, even though they have always had a range of products from cheap to crazy expensive. at least they have some low end stuff for those of us who are poor.

One year after you presented this video it seems that DSD is making a resurgence. There are more than several recording companies that are going for DSD and to my ear they sound outstanding. Mark Levinson was one of the first to be a huge promoter of the SACD and if anyone is lucky enough to find his Red Rose sampler CD I think you will be in for a big surprise. Mark was actually able to get some of the best jazz musicians in New York City to record at least half of the music on this sampler and it’s almost impossible find now. The sound is nothing short of spectacular. I was lucky enough to purchase one from Mark when he opened a very small Red Rose audio salon on the east side of Manhattan. Among the new start ups is Octave Recordings which was started by Paul McGowan of PS Audio. He’s totally bought in to this DSP technology. I have listened to a few of his releases and they are incredible.

[@anadialog]

I agree, high quality DSD recordings are amazing. Thanks for sharing the Red Rose Samples info!

Red Rose equipment was pretty cool though. I’m not sure who the designer of his electronics was under the Red Rose brand and the speakers as well. The CD player was a Sony SACD obviously. We spent about 20 minutes until he had another listening appointment.

Thank you for this really excellent video and for sharing the files. This is the first time I've heard DSD on my DAC (Chord Hugo2). The track selection is also excellent. The higher resolution WAV files are definitely at a higher volume than the DSD which initially makes them sound more impressive. Normalising the volume, the higher rate DSD are very natural with each instrument clearly defined.

[@JesusMartinez-mk6fc]

One issue for many audiophiles with playing DSD material, whether through dowloaded files or SACD discs, from the source to a DSD capable DAC, is that you can't do any manipulation whatsoever to the DSD signal without first converting it to PCM, which pretty much throws out the window the claimed SQ advantages of DSD under those circumstances. If for instance you want to use any form of DSP like bass management, digital room correction (e.g. Dirac, ARC, Audiolense, Audyssey, etc) or even plain parametric EQ to reduce bloated bass caused by room induced standing waves, you have to convert the DSD signal to PCM as any of those forms of processing can't be done under DSD. It's the same problem sound engineers are faced with in the recording studio. If they're going to do any mixing or signal processing as simple as a gain change, they have to convert a portion of the DSD signal to the DXD format (PCM), perform the desired processing in PCM and convert it back to DSD. Alternatively they could perform that processing on analog tape and convert it back to DSD. There exist no algorithms or math to perform an operation only on a one bit sample. That's why there are so few pure DSD recordings as indicated by the passionate host of this channel. I have a descent collection of SACD recordings whether in classical music, jazz or rock and I personally find a greater benefit of using bass management to properly integrate my subwoofer and adding digital room correction than listening to that same recording in pure DSD mode directly decoded by the DAC. I believe that what has the greatest impact on SQ is the care taken by the experienced recording and sound engineers when producing the DSD recordings or any other format for that matter.

[@ABC-rh7zc]

True, and there is literally no advantage to DSD. Just let it die.

[@limp6986]

Room correction dsp doesn't fix the sound of your room. Get proper room treatment instead. But you already know that...

[@JesusMartinez-mk6fc]

@@limp6986 I don't believe in idealistic and absolutist statements like the one you've made. Reality is more relative as Einstein would argue. I used to be more of a purist in my younger audiophile days. However with time and experience I've leaned to become more pragmatic and base my decisions on a more scientific and evidence based approach. I'll start by addressing your second statement, i.e. your recommendation regarding room treatments. While I agree with you that proper room treatments should always be the first step, it's not always practical or even possible in every situation. Not everyone has the luxury of having a dedicated audio listening room large enough to accommodate room treatments. Think of a lot of places in Europe or Asia where appartments can be fairly small and even in North America in certain urban centers. I'll take as an example my own appartment. The only even remotely adequate room at my disposal is the living room; it's small at 13 x13 x 8 feet (4 x 4 x 2,4 meters). The right side is mostly flanked by two windows and a door leading to the balcony leaving no room for any treatment except for corner bass traps. The left wall is occupied by a couple of bookcases that contain my CD and Blu-ray collections while the front corner harbors my audio gear rack and the back corner is the entrance to the room making even the placement of corner bass traps allong that wall impossible. The only walls left for possible treatments are the front and back walls plus the ceiling. And I know of many people in similar situations. Furthermore, good luck with your second half letting you turn her living room into a recording studio. On top of that, add my 65-inch TV with a basic 5.1 multi-channel speaker setup, no way to even accommodate a 7.1 setup although I'd like to add a second subwoofer in the future. I hope you get the picture by now. So yes, as you stated, I know that proper room treatment is the ideal first step but as I hope you may have come to realize, it's not always practical or possible in every situation. Now I'll address your first statement that room correction DSP doesn't fix the sound of one's room. There are many acousticians with PhDs that develop digital room correction (DRC) technologies, e.g. Acourate, Audiolense, Audyssey, Anthem ARC, Dirac Research, DEQX and Trinnov to name a few, that would strongly disagree with your opinion and that have performed many studies published in audio journals such as the AES. Many professional acousticians also use parametric EQ on top of room treatments to help reduce room standing waves even further. Realistically, no technology whether room treatments, DRC or DSP EQ can completely fix the sound of a room but from experience, I know that even DRC on its own can make a dramatic improvement in reducing standing waves and opening up the sound for the better.

[@anadialog]

[@bsweet1492]

I listened to the PCM vs. DSD selections repetitively and there is one problem with this comparison that my ears picked up. The volume of the PCM tracks is louder than the DSD tracks. And typically something that plays louder usually sounds better, at least initially. Anyone doing a listening test to compare the PCM vs. the DSD should pay attention to ensuring the playback volume is equal. It would also be nice to know the provenance of each track, as this can make a difference in the sound quality. I.E. how was each track originally recorded, mixed and mastered, are any of the tracks up-sampled, how were they up-sampled, etc.? This gets to the point made in the video about "certification" of the derivation of the music we are listening to. Regardless, to my ears, the PCM 192 and 352.8KHz did sound really good, but once volume was equilibrated, my ears preferred the better resolution and less glare of the DSD 128 and 256 tracks of the "Saxaphone". On "Pictures", my ears told me the DSD was far superior to the PCM 192, even regardless of the volume difference.

[@EllasPOSEiDON]

Indeed. DSD been created to make artifical linearity of analog sound wave. With that in mind that insane sample rates / second at least trying to create that. That is why superior to PCM, at least in my opinion. Anadialog is very right when his pointing that out making a record in native DSD, then convert it to pcm is a non-sense step. Logically obvious. You record something in pcm, then convert to mp3, then back to pcm? :) Funny movement even from studios and I think that is just a stupid and lazy explanation instead of using pure DSD all over the recording line. Better to record everything in full analog, master and mix in analog, and then, only after that you can record it purely to a user ready DSD. Sounds simple, but for cost cut, etc. they just cheat, most of the time. Every kind of conversion leads to degradation in sonic quality, upsampling is also part of stupidity in audio. You CAN NOT get any better from your source doesn't matter where and how you convert it. Still can't believe how over their 20's (think so) people can even think about it. One more word for Anadialog. I am 100% with you with the certification theme, how can we trust or believe what we paying for? Mostly no explanation how did they sourced their files, which is IMO really frustrating and dishonest with all the consumers.

[@romualdasseman9158]

The DSD has got a fine DB rate and is not compressed as the Flac (not the codec) probably using 16 bit for 44kHz can be. If you turned down the level of the DSD you cannot hear anything but i have to get the cue sheet for instance made out of Foobar to see the comparaison between the level of compression so that the dynamic is evacuated out of the range of that possibility. But then the phenomenon is rather normal due to the DB and i wondered how did you miss that point.

[@romualdasseman9158]

I Edit: this the same record then, a compression was applied on both maybe 10 if there is a large portion of music that differs, normally if that portion of dynamic is low, you can be sure to find a louder DSD too but on a different level due to the excellence of the DB, you should feel a form of noisy background. Is the flac and the DSD compressed equally ? DR please.

Just discovered this channel, very interesting, I just downloaded the files and certainly will provide my feedback, while it seems based on the comments DSD is preferred just let's take into consideration the actual test is being performed with a Sigma Delta based ADC (Analog to Digital Converter), each method of conversion ADC and DAC has its pros and cons and SDM based ADC's / DAC's tend to provide better conversion encoding and reproducing DSD content. There is also an endless amount of noise shapers, modulators and filtering techniques which most of you knowing what HQPlayer is probably will know. Also when listening to the results the DAC side will use either SDM chips, FPGA's, PCM based R2R ladder type conversion which will (poison is the wrong word) but will taint and steer the results towards the method of reproduction. To the channel owner thank you for the content you provide, I hope you don't take my comments the wrong way, I'm just saying the testing method encoding and deconding (playing back) the music "could favor" DSD over others

This is of fully analogue construction and constitutes a genuine one-bit converter, since - unlike other manufacturers - we did not want to use the DSD mode of a PCM converter.

By recording in DSD even if you transfer to PCM and back to DSD, the mastering on SACD's will always be better because it avoids the loudness wars.

I also want to say that the DSD files played at the same volume level as the PCM were not as loud and seamed less detailed. but, when I increased the volume to match that of the PCM they had, to me, a touch more resonances and a bit more detail. The Bass notes were a bit more defined. Both systems got better with higher sampling rates.

Nice to see you again. No questions - DSD is better sounding - I have tested them myself. My problem with DSD is that most audiophile preamps/integrateds do not offer HDMI inputs. Therefore, most SACD players have to convert the signals into PMC - negating the benefits of DSD signals encoded onto the SACDs. Also, OPTICAL and COAXIAL cables cannot carry DSD signals (what you get is 44.1K/16bit). BUT, there is a better sounding format (even beating the DSD) ------> R2R tapes!

Excellent video. Thumbs up. Looked at the Mussorgsky files on MusicScope. DSD frequency spectrum looks very clean, but the PCM has two noise spikes one at 76.9kHz and the other at 95kHz. They vary slightly in amplitude during the track, but are mostly fixed. Fixed pitch ultrasonic tones can cause audible problems (broad spectrum ultrasonic noise in DSD doesn't). Nelson Pass tells a story of Telarc producers having a problem with the sound of a recording. Using frequency spectrum analysis, Pass discovered a 35kHz tone in the recording, which was the cause of the problem. As far as PCM, no delta sigma DACs over here. NOS ladder DACs fix most of the problems with PCM playback for me.

I think it pertains to your excellent "Sound beyond 20 kHz" video. The ultrasonic tone may create a "dysharmonic" effect that is very unpleasant to the listener. The anecdote may be in this YT video kzbin.info/www/bejne/baacgH6GgZaYsKM starting at the second harmonic distortion generator discussion. Also, interesting topic. In phase 2nd harmonic creates detail and presence. Out of phase 2nd harmonic creates an illusion of spaciousness and increased soundstage.

Still scouring the World for Mo-Fi Original Master Recording and Japanese SHM SACDs simply because they sound so damn good on my system and to my ears in comparison to vinyl or CD.

[@soundman-sm2hc]

I think the best way to understand the difference between PCM vs DSD is to look up the difference between Pulse Code Modulation and Pulse Density Modulation. It tells you everything you need to know. Don't get too hung up on signal to noise ratio and frequency response. It's all about bit depth, aka the number of times a digital converter takes a picture of the analog waveform. If you use the photograph analogy, think of it as how many times a second does digital take a picture of the analog waveform. More pictures in a given period of time means better resolution.

I never heard digital audio sound so good than with DSD files thru my external DAC player. It just sound fuller and more appealing to my ears. I'm in the process up upsampling my Flac files to DSD256 and loving the results.

[@wahid-lg1kk]

It's pretty hard to get good dsd files, real native dsd. A lot of it online as well, is ripped from vinyl with the same dynamic range of vinyl and tons of noise. A good dsd 256 is just better then anything else. It's fluid as liquid, pours out like water. SACD is dsd 64. Sounds real good as well with modern dacs. Most of my dsd is 128, but as I said it's real hard to get, unless you are wealthy and can buy it online for big bucks. I don't like PCM. Upsampling is bunk. I don't use computers to play music files. I use a DAP with hardware DAC, not a chip. I also have a small unit with two ESS Sabres, big difference but the small one can go in my pocket. I really like your explanations. I have tried to tell people that the air up above 22khz affects the audible noise, no one believes me.

Interesting video! My only device which fully supports DSD playback is my Sony Walkman NW-A45 (I'm very happy with it btw). However, using a pair of Senheiser HD650 headphones I have to be honest and say that I could barely tell any differences between the DCD and the hires PCM files, they all sounded great to me. I may have said otherwise if I had access to a proper DSD playback device in my stereo system.

[@johnmarchington3146]

Thank you for an excellent video. Just a couple of comments. I think you mentioned early on that Sony is no longer supporting SACD and that's true. I was told by a friend that the reason for that decision is that an opportunist pop artist, who records for Sony, thought it might be possible to extract three lots of royalties (CD layer, SACD layer and multichannel SACD layer) for every copy of the artist's many SACD albums that had sold and when Sony refused to oblige, that artist took Sony to court to contest it and won. Sony decided that would set a precedent and immediately decide to stop producing SACDs. A recent KZbin video I watched involving PS Audio's CEO Paul McGowan, who is convinced that DSD is the most analogue-sounding digital format currently available and superior sounding to even high resolution PCM formats, mentioned a filter called a Zephyr filter that I believe PS Audio is developing for its Octave Records productions and my understanding is that he thinks it could provide the ideal answer for editing DSD files. I have no idea how far advanced that development is, and I guess only time will tell if it will work as anticipated. I love DSD myself and have bought a number of albums from Native DSD Music and I also have a large collection of SACDs.

Why, standard redbook 16bit/44.1khz is more than enough for human hearing. DSD and high sample rate audio usually just sounds better because the original recording or remaster was done with high fidelity in mind. DSD almost always starts out as PCM for mastering and then converted to DSD. SACD was a BS move by Sony for better copyright protection and to resell their audio catalog all over again and double dip you wallet.

I have heard of the album but I haven't listened it yet. If you have been following me you know my point of view. If they did a dediated master for the vinyl version its ok to get a digitally sourced vinyl. I just try to stick to 100% analog when we are talking of the past century pressings.

[@bluevoodooiv7072]

Thank you for the informative video. I wondered how I'm supposed to perform your test because your sample files are not volume matched between DSD and PCM?

[@anadialog]

I can't. That is the output of the recorder with the same source volume. You need complex software to edit or simply compare DSD, as we said. This is another aspect of DSD and PCM. A higher volume of one is an intrinsic aspect. You can do it in an empirical way, by changing volume looking at VU meters but as we all know perceived loudness is something that needs to be measured (LUFS) in order to have the same true precise volume.

[@Lasse3]

A 22050hz Sine wave sampled at 44.1khz is described by a single sample per half-wave, this is the minimum amount of samples per half-wave required to produce a frequency, resulting in a brick wall at 22050hz, when using the 44.1khz sample rate. *No* amount of bit-depth can increase the amount of samples, increasing bit-depth only increase SNR. Higher Bit-depths allows the samples a more accurate amplitude, but 2 samples will still only be 2 samples. You have 65,000 different possible positions to put your 2 samples in at 16 bit depth! If we increase the bit depth to 24 we now have 16,777,216 possible positions to put the 2 samples in! The brick-wall is still occurring at the exact same frequency. I've heard people refer to the 'kbps' of a recording, as if that is the "Resolution" you calculate the kbps; 16bit (96dB SNR) x 44.1khz (sample rate) => 705.6 x 2 = *1411.2 kbps* So what's being done is multiplying the SNR with the sample rate, and they believe the kbps will represent the 'resolution' While in reality, all the kbps (kilobits per second) tells us, is how much harddrive space a second of this soundfile will take up on our harddrives. DSD's entire worth of kbps is in samples, there ain't no Multiplying SNR with Sample rate when it comes to DSD. So comparing DSD and PCM's amount of information "kbps" is ridiculous. Here are three examples: 32bit/44.1khz= 2822kbps 24bit / 48khz = 2304kbps 16bit / 96khz = 3072kbps What did we learn from this? that 16/96 sounds better due to having more information? I'm afraid that ain't the case. 32/44.1 SNR of 192,96 dB 4294967296 levels of amplitude sample rate of 44.1khz 24/48 SNR of 144.49 dB 16777216 levels of amplitude sample rate of 48khz 16/96 SNR of 96.33 dB 65536 levels of amplitude sample rate of 96khz Would 32/44.1 sound best because it had the highest SNR? Or did 16/96 sound best due to having the highest sample rate? Did 24/48 sound worst due to being the one containing the least amount of information? DSD128 5.6mhz has 25 samples per half-wave at 112 khz. And please try to remember that 44.1khz / 16bit would only have 22 samples per half-wave down at 1000 hz. At 1000 hz DSD5.6mhz would have 2800 samples per half-wave, that's 30% more samples than a 1920x1080 wide-screen monitor has pixels horizontally, just to give you an idea of just how closely these samples are fitted together. When you choose sample rates like 44.1khz or 192khz, your 10khz-20khz audio spectrum will digitally speaking be a square signal trying to describe curved analogue electrical currents. The PCM format will be playing 'connect the *few* dots' using all the tricks in the PCM book. while the DSD format simply sampled the analogue source at such extreme rates, that by sheer density' the samples themselves will be drawing solid smooth curved lines, how people fail to comprehend this is beyond me.. I've heard people say, and it seems to be a regular saying among the PCM crowd, that 24bit / 88khz is 'the same' as 2.8mhz DSD... how they end up at that conclusion based on kbps is laughable. 88khz sample rate will describe a 20khz sine wave using 4.4 samples, how are these 4.4 samples as good as DSD 2.8mhz's 140 samples at 20khz? There exists actual purchasable music at DSD 11.2mhz, at such high sampling rates even a 20khz sine wave will consist of 560 samples. 16/44.1 needs to be all the way down at 78hz before it starts having that many samples to play with. *DSD* SACD 2.8mhz 1bit x 2800khz => 2800 * 2 = 5600 kbps What we have here is 5600 kbps worth of samples, in other words 5600 kbps worth of actual resolution. Then let's do a PCM 24/96 24bit x 96khz => 2304 x 2 = 4608kbps Please understand that we are only dealing with 192kbps worth of samples.. 96 x 2 = 192 (2 channels) Multiplying the 24bit SNR with the 96kbps sample rate gave us 4608kbps. Producing multi-bit PCM chips capable of worthwhile sampling rates has not yet been done, during the roughly 36 years where PCM chips have been the standard, which is why i refer to PCM as being inferior. It's true that DSD in reality has a very low SNR since it's only 1bit, which in theory would only provide a 6dB SNR. By using noise-shaping they increase the SNR, without having to imbed that method into the digital signal, it's strictly hardware based. This is very advantageous because the 1bit DAC can handle extremely fast sample rates, while performing at +120dB SNR, which is more than enough, as i said previously, you have SNR bottlenecks elsewhere. In other words, the way DSD obtains its SNR is not stored as information as PCM would, so comparing their amount of information is a mistake. 11.2mhz quad DSD 1bit x 11200 => 11200 * 2 = 22400 kbps 24 bit / 192khz sample rate 24 x 192 => 4608 * 2 = 9216 kbps So if we were to assume ( which we shouldn't ) that kbps said it all, then Quad DSD has 60% more 'information' than 24/192 pcm, and should sound 60% better. People who believe in PCM will claim that 1 sample per half-wave is as good as any amount of samples, as long as the frequency can be produced, i say to them, *Then why go above 44,1 khz sample rate?* The simple fact is, that during the 80ies when the first Pulse code modulation chips were realized, 44,1 khz was an impressive sampling rate, which were hard earned at the time. It was capable of reproducing the sound, and it was much easier to mass produce, ship and store than Vinyl. This is why it was pushed unto the ignorant masses, who still to this day, listens to the same 44,1 khz sampling rate, 40 years later. And somehow it was favorable to downgrade from the CD's (1411 kbps) all the way down to mp3's (320 kbps) I'm currently sitting here with my TEAC UD-505 OctaDSD dac ( 22,4 mhz sample rate ) *DSD512* A single second of the DSD512 format takes up 5,4 mb of hard-drive space, with a whopping "resolution" of 45158 kbps. Remember CD's 16/44,1 only had 1411 kbps worth of "resolution" -Hitashi

Some notes for those who might have downloaded the files for the test. Even though my preamp/processor decodes DSD and has an active USB port for input, it did not even recognize the DSD files and thought those folders were empty. (I think this might be because some hardware will not decode DSD over a USB port.) So, I plugged the USB into my Oppo, which also supports DSD. Even though the player recognized and listed all the DSD files, it would only play the DSD64 file. I'm not sure if it was the Oppo and/or my pre-pro that could not play 128 and 256 files. As for the test, my expectation going in was that I would hear no difference. To my surprise, my ears heard a fairly large difference between PCM and DSD. I found the DSD to have much more depth and "3D" type of sound, more detail and texture, and more "air" between the instruments vs. the PCM. I was impressed.
