In my own experience in the audio recording world, using a single, high quality, low jitter, external master clock for all AD/DA devices such as audio interfaces with word clock inputs, digital recorders (like the Korg MR-2000S), external analog-to-digital and digital-to-analog converters (like a Black Lion Audio Revolution EXP ADAT expander, RME ADI-8 DS) - makes a significant and quite audible difference. In fact, the majority of major recording studios (recording digitally) will use a high-end master clock for all of their digital devices. Upgrading my master clock made a big difference in my studio in both the recordings I make and playback.
I'm happy with the Schiit Bifrost 2 DAC. It has separate clocks for 44.1khz and 48khz integers, and a switching relay that clicks to let you know when the audio frequency or bit depth has changed. It's just one of those things that satisfies my OCD for bit perfect sound. Now if only it supported ASIO.
A little of what you said is correct, but the overall conclusion is likely out of whack. You are correct that long term stability is meaningless. It is all about close in phase noise. The impact of improving this performance in digital audio is MASSIVE. If I am not mistaken, Chris speaks to the importance of this in PSAudio blogs. He cites the impact of the clock choice on the Direct Stream DAC. So I checked. It uses a Crystek clock. Like most sub $10k DACs. It is a good clock, but entry level in audiophile land. The Crystek CCHD-957 24.5 MHz clock has a phase noise at 10Hz of -97.950dBc/Hz. The clock I use measures -150dBc/Hz at 10Hz. Let me tell you the difference in sound is reasonably good digital sounding DAC vs natural nuanced analogue playback. It is a dramatic improvement. Every step up in close in phase noise on the same DAC yields more of the holly grail we all seek. Of course, the rest of your system has to be transparent enough to allow the good stuff to come through. But most peoples systems are severely limited in the source. By comparison, a power cable can make a nice change. Is it worth $5k. No way. Could a clock be worth $5k? Absolutely. Mine is a DIY DAC. The Crystek is about $35. My clock might be $200. But my DAC with that clock will smoke any commercial DAC under $20k. A commercial clock with these phase noise numbers will be over $10k. So your advice is IMHO dead wrong. Your own DAC designer Chris would fully agree BTW.
I think however good is an external clock, if the input source has jitter, no perfect clock is going to help cleaning it. The external clock is useful to sync an interface to another, a DAT.. Best clock is the one that generates AND decodes the signal, such as a standalone CD Player. The moment you introduce a dac with another clock you have got to lock to the input clock signal, and you need tricks such as resampling or PLL (correct me if I'm wrong), that degrade the signal, because sooner or later it's going to drift. Optimal thing would be an external clock that manages both the input and dac clocks.
Like you say, I don't think accuracy is that important like people say in a two channel DAC device... Other ways.... If you think in a studio environment, where let's say you recorded drums in your studio, then the guitars and bass are recorded at home using different gear, vocals in an other one, and then again mixed and mastered in the first studio I say, holding up 100+ tracks.... that's when I think there is a different because of stability. Not in a long term of playing music during two years, but because you get more accurate (or more equal) reproduction compared to when it whas recorded. Like in live situations, having different digital consoles, stageboxes and interfaces in the same time, sync them with one clock or another, sync them to the more accurate one seems to always sound better. And in theory it makes sense. Thanks for your videos and posts.
Modern clocks are so precise... If your equipment is good, the upgrade should make no real difference. You can test it but don't expect that much. Powercables could be a better option, but it's all about matching, not about price. A good match is far better than a random expensive cable. Take care of the placebo effect...

my vote is for Nordost Vahalla cable. I auditioned the USB cable and it's amazing. Wish I didn't try it - cannot unhear it. If you have a good DAC, it should have a good clock.. external clock is snake oil. lol....
I think the idea isn't that the dac doesn't have a good clock, and more to do with upgrading the existing clock. I think of it like a preamp might come with a good MC/MM phono but a better quality external phono will be an upgrade.

Please show me on a scope or some type of testing equipment that changing out power cables actually makes an audible difference. It does not, and never will, unless the OEM power cable was extremely inferior, which most are not.
Try hooking it up, take a reading then bend the cables at a 90 degree angle then look at the difference then you won’t have any doubts that they make a difference!
Power cables are my next “to try” product. Wasn’t a believer of cables before but now i upgraded my interconnect and speaker wires. I hope power cables can improve my modest system.
A Power cord can make a noticeable difference if you have a revealing system (PMC/Naim here)…. But in our experience, a dedicated AC line (AWG 10-14, as a dedicated circuit) makes a HUGE difference, far bigger than the power cord, and is a lot cheaper. Cheers
Just to throw a wrench, i have seen, in person as well, measurements on power cables, expensive and even rusted ones. And there is just negligible difference in what they deliver to the equipment.

@@Harald_Reindl but the audio ones are called world clocks which to me implies that they provide a single source of time for all the equipment. Clocks have multiple output connectors.
Valhalla 2 power cable…. I’m guessing that’s about a $5,000+ dollar cord. No one buys a top tier cord like that, unless you have an equally top tier DAC or CD spinner from the crowd like dCS, MSB, Esoteric Grandiose (sp?), Luxman D-10X and the list goes on. If one has equipment that starts at around $20 large, it’s already got the top of the line DAC-clock combo in it, so getting a better clock would make likely little to no difference. Let’s say one has a spinner from 2010 like an Esoteric K-1 which was a $20 large spinner in its day but the DAC is no longer up to say an the resolving capability of an ESS Sabre DAC with 8 channels, or the TI 17XX chip set, then getting a new DAC would definitely help, as the transport in that K-1 is super solid. Back to that power chord, have a good power conditioner like a Synergistic Research UEF/FEQ combo, and put some Black Diamond cones underneath it, and put a Symposium base underneath it all.

A stable clock has an effect on the sound quality, I have experienced, but it is better to invest in a good DAC, which has a low jitter level or no jitter at all, eg Benchmark DACs, which have an amazingly good sound and do not care with how much jitter it is exposed to from external devices such as CD transports, music streamers etc.
Every crystal oscillator has a temperature at which it performs best. Typically around 85C. So an oven is employed to keep the device at its optimal temperature improving its close in phase noise and delivering a noticeable improvement in sound quality in a digital playback system.
Good digital audio equipment have a clock signal coaxial connector at the back. You’ll need a clock that matches the frequency the device is expecting. Some clocks have frequency selection. Having said that, modern systems use a standard 10 MHz clock signal for easy compatibility.
So like a CD recording is sampling the music 44,100 times a second. There are that many data points that your player needs to read and transmit in exactly a, second. So now imagine what happens to the sound if the timing on your player doesn't match the timing of the recording? Basically youre either speeding up or slowing down the playback. Secondly what if its inconsistent, ticking a little faster sometimes and a little slower sometimes. The music will now be warbling all over the place. But my examples are extreme. As Paul said, if we're talking femtoseconds, you definitely can't hear it.
@@RasheedKhan-he6xx This is a very good explanation. Again as I mentioned, the idea is that an external clock is called a 'world clock'. You want your CD transport and DAC to tick according to the same clock so they are in-sync. You're right about not being able to hear the effects of the audio pitch changing due to the clock speeding up or slowing down by such a little amount.

I would ask this question to Hans Beekhuyzen. He's the digital audio expert, and he's definitely knowledgeable enough to know which choice is best. This isn't Paul's specialty, as you can tell by his answer that made very little sense to me. I've never ever heard of a clock for digital audio being advertised for long term error avoidance.

So I wouldn't be too concerned about it, if I were you. Thank God I'm not though. Have a wonderful night sir. ✌️
Hans Beekhuyzen? Are you serious? Apparently you, like Hans, think MQA is a superior digital format when in fact, it's been an inferior format since the day it was released. Obviously, this isn't your area of expertise either. Nor is it Hans. Many of the comments in this channel on this topic really seem to bring out the true colors of mainstream high-end audio. And it ain't pretty.
Two critics, and not one positive word offered between either one of them. No alternative offered. No explanation on why you're attacking the man, other then one of his opinions. On one single little subject. Not very strong arguments by either of you. With zero advice given by either of you. You both may as well have on a t-shirt that says "I'm an internet troll", because your behavior reeks of it. Probably a couple of ASR Cultists with too much time on your hands. At least I was trying to offer a hand, and help. You've both offered nothing, but negativity, and attitudes. Didn't your Mother ever tell you that if you've got nothing nice to say? Say nothing at all. I'll stick by Hans, myself. At least he has the courage to put himself, and his opinions out there to be criticized on a weekly basis. What have you two done to help out the audio community lately? I think we all already know the answer to that question though. Don't we? Nothing!
I read a few of these comments and they are a laugh :). External clocks ARE NOT an upgrade of the internal clock found on a DAC. They complement the DAC's clock in long term stability and lowering its jitter. This kind of add on, only makes sense on very high end systems where you can really hear the improvements, believe me !! No wonder most people make jokes of this, they don't know better and should be forgiven for they're ignorance. This is a case were "Ignorance is bliss". Adding an external clock is fine tuning and should always come after all the cables in the system are chosen. What to expect from this upgrade ? Only resolution, for those that didn't experiment it yet; imagine a choir being played through your HiFi system, by adding an External clock, you can differentiate all the individual voices in that choir, if remove, you would only listen to the choir mass of sound. Another improvement is with instrument separation and voices, they became a lot more natural (silky smooth) Hope this helps
@@AccuphaseMan I’m sure PS audio’s engineers are designing excellent internal clock circuits. Concerning dcs valdi, we are talking over-priced snake oil. Paying US$15,000 for a clock generator driving a DAC is nothing more than idiocy.
Paul, I enjoy your videos but in this video, you clearly show that you have absolutely no idea what you're talking about. May I suggest that you do some research prior to making a video on this very important topic for audiophiles with high-end audio equipment. For audiophile with lower quality equipment, this topic may not be relevant (ie they may not be able to discern any improvements in the sound quality). In general, I would start with power cable which do improve the sound quality in most systems but the cost of the power cable should match the quality of the equipment and the hearing ability of the individual. There's no point in upgrading the power cable if one cannot hear any improvements in their sound system or don't really care about any improved sound quality at all.
I don't believe most people can hear improvements even on the most expensive gear sure they claim as such but people usually feel the need to lie when large amounts of money are involved.
@@ryacus You're exactly right. That's because many cannot audibly discern / interpret what they hear. For some reason they think they're born with such discernment perhaps because they have 2 ears and passed a hearing test 2 years ago. It's by far the greatest weakness in this industry and that's why so many cling to high cost equipment and to measurements including audio reviewers and even editors-in-chief. Nobody expects a critique of the fine arts to be born with the ability to discern what he sees without an eduction and training his eyes. Yet, in "high-end" audio, there are seemingly highly-educated types who think it's an in-born talent. In fact, I have every reason to believe that the creators of MQA banked on this lack of listening skills among the masses such that if they could get a couple of editors-in-chief to endorse the MQA product with claims like "experiencing the birth of a new world" by John Atkinson of Stereophile and similar crap from Robert Harley of TAS, the masses would follow suit and many believed. Thank goodness the MQA effort seems to have failed so far but in the process have convinced so many that it was a superior format to anything else when in reality it wasn't much better than mp3. All because so many have checked their brains and ears off at the door. And frankly that's why I commented above about Kenneth.
In my own experience in the audio recording world, using a single, high quality, low jitter, external master clock for all AD/DA devices such as audio interfaces with word clock inputs, digital recorders (like the Korg MR-2000S), external analog-to-digital and digital-to-analog converters (like a Black Lion Audio Revolution EXP ADAT expander, RME ADI-8 DS) - makes a significant and quite audible difference.

A good DAC should have a good clock inside already. On the other hand, audio switches can benefit a lot from a good external clock and power supply.
if your electronics are not highly resolving forget all these upgrades ? cables or clock LOL if you have a real high end system then start with cables / most people do not know what real sound even is ? when they hear real sound they dont like it they are so used to ss amps colouring music x
I would ask this question to Hans Beekhuyzen. He's the digital audio expert, and he's definitely knowledgeable enough to know which choice is best. This isn't Paul's specialty, as you can tell by his answer that made very little sense to me. I've never ever heard of a clock for digital audio being advertised for long term error avoidance.
@@HenryLaw19891024 Did you actually read what I wrote? Or are your reading comprehension skills really that awful? I guess there's also a very possible third option, which is that you just felt like being a jerk, and/or starting trouble. But either way. Why I'm here is none of your business anyway. So I wouldn't be too concerned about it, if I were you. Thank God I'm not though. Have a wonderful night sir. ✌️
@Taco Cope harder
Hans Beekhuyzen? Are you serious? Apparently you, like Hans, think MQA is a superior digital format when in fact, it's been an inferior format since the day it was released. Obviously, this isn't your area of expertise either. Nor is it Hans.
Many of the comments in this channel on this topic really seem to bring out the true colors of mainstream high-end audio. And it ain't pretty.
"I would ask this question to Hans Beekhuyzen. He's the digital audio expert".
I too would strongly disagree.
Two critics, and not one positive word offered between either one of them. No alternative offered. No explanation on why you're attacking the man, other then one of his opinions. On one single little subject. Not very strong arguments by either of you. With zero advice given by either of you. You both may as well have on a t-shirt that says "I'm an internet troll", because your behavior reeks of it. Probably a couple of ASR Cultists with too much time on your hands. At least I was trying to offer a hand, and help. You've both offered nothing, but negativity, and attitudes.
Didn't your Mother ever tell you that if you've got nothing nice to say? Say nothing at all. I'll stick by Hans, myself. At least he has the courage to put himself, and his opinions out there to be criticized on a weekly basis. What have you two done to help out the audio community lately? I think we all already know the answer to that question though. Don't we? Nothing!
My vote is to listen to the performance, not the equipment.
I read a few of these comments and they are a laugh :). External clocks ARE NOT an upgrade of the internal clock found on a DAC. They complement the DAC's clock in long term stability and lowering its jitter. This kind of add on, only makes sense on very high end systems where you can really hear the improvements, believe me !! No wonder most people make jokes of this, they don't know better and should be forgiven for they're ignorance. This is a case were "Ignorance is bliss".
Adding an external clock is fine tuning and should always come after all the cables in the system are chosen. What to expect from this upgrade ? Only resolution, for those that didn't experiment it yet; imagine a choir being played through your HiFi system, by adding an External clock, you can differentiate all the individual voices in that choir, if remove, you would only listen to the choir mass of sound. Another improvement is with instrument separation and voices, they became a lot more natural (silky smooth)
Hope this helps
"red" Funny, all I see is 'black' print.....................
A DAC that needs an external clock does not deserve one...as it's not a well-designed DAC.
+1.
take a look at dcs vivaldi
Never heard him say his dac needed one. Think you're putting words in the guy's mouth.
@@AccuphaseMan I’m sure PS audio’s engineers are designing excellent internal clock circuits. Concerning dcs valdi, we are talking over-priced snake oil. Paying US$15,000 for a clock generator driving a DAC is nothing more than idiocy.
@@ThinkingBetter Why so?
4 minutes and 20 seconds of feel-good audio vibes
not even wrong
SIGH
As soon as BS Audio starts making external clocks this video will be pulled..
I hope you didn't mean (bull) Schiit Audio. They make some really good schiit.
@@raffiequler7510 No I meant PS Audio
They won't. Bet a frosty 24 pack on that.
Upgrading the power cables without doing anything about the house wiring seems pointless. Install a good power conditioner first at least.
Paul, I enjoy your videos but in this video, you clearly show that you have absolutely no idea what you're talking about. May I suggest that you do some research prior to making a video on this very important topic for audiophiles with high-end audio equipment. For audiophile with lower quality equipment, this topic may not be relevant (ie they may not be able to discern any improvements in the sound quality).
In general, I would start with power cable which do improve the sound quality in most systems but the cost of the power cable should match the quality of the equipment and the hearing ability of the individual. There's no point in upgrading the power cable if one cannot hear any improvements in their sound system or don't really care about any improved sound quality at all.
Most of your comments here are nonsensical. But certainly indicative of a mainstream "high-end" audio mindset.
Kenneth, you need to spend more time watching videos about Schiit Audio products on their channel.
I don't believe most people can hear improvements even on the most expensive gear sure they claim as such but people usually feel the need to lie when large amounts of money are involved.
@@ryacus You're exactly right. That's because many cannot audibly discern / interpret what they hear. For some reason they think they're born with such discernment perhaps because they have 2 ears and passed a hearing test 2 years ago. It's by far the greatest weakness in this industry and that's why so many cling to high cost equipment and to measurements including audio reviewers and even editors-in-chief. Nobody expects a critique of the fine arts to be born with the ability to discern what he sees without an eduction and training his eyes. Yet, in "high-end" audio, there are seemingly highly-educated types who think it's an in-born talent. In fact, I have every reason to believe that the creators of MQA banked on this lack of listening skills among the masses such that if they could get a couple of editors-in-chief to endorse the MQA product with claims like "experiencing the birth of a new world" by John Atkinson of Stereophile and similar crap from Robert Harley of TAS, the masses would follow suit and many believed. Thank goodness the MQA effort seems to have failed so far but in the process have convinced so many that it was a superior format to anything else when in reality it wasn't much better than mp3. All because so many have checked their brains and ears off at the door.
And frankly that's why I commented above about Kenneth.
Anyone claiming power cables can change sound I have zero respect for.
