This is the best explanation of the mscaler! Great job

Your best yet mate!

Thank you again for a sound comprehensive review of the M Scaler and TT2. As you suggested I also listened (a couple of times) to your really good 4 Part interview with Rob Watts. Your explanation of the differences between an analog and digital was also great. I have been debating the best way to go with a dac. We have a highish end system so need an appropriate level dac. I was steering towards a high end RtoR dac but may now switch to a Rob Watts dac. The science behind his products is compelling enough. Thanks again. Keep up your great work 😎👍

Fab review and insight.

I almost understood. Thanks for trying!

I wonder why it took so long for such a relevant review on the mscaler to emerge. Well done! Best macaler review on youtube. Relevant as you cover how an end user can use it in the different scenarios and you have tested those scenarios. Succinct, on point.

Thanks for the review. Here's the info I gathered and my thoughts after watching it: - Improving source (DAC output) does make a difference in overall system sound quality. - Even high-end DAC like Hugo TT2 still has room to improve. - This M-scaler does upsampling/reclocking (I'm oversimplifying), which can totally done by software/chips inside DACs. A lot of other products are doing this already, just that M-scaler does it better with dedicated hardware. Digital techologies are improving so fast that I can totally see in 3-5 years a 1000-dollar device can do what M scaler does today - look how far Chi-Fi has come along. It makes little sense for most people to invest in an M scaler, unless you want to get the best sound quality currently available. For the rest of us, getting a 2k$ DAC every 3-5 years makes more sense.

Well made very informative video.

Thank you for the explanation. I likely will never get something so fancy but I understand the reason for its existence just starting in to hifi. Suggestion flesh out the waveform analogy with exaggerated data points. When I filled out in my mind it became clear to me what it does.

Well done - another concise and clear review. Timing is the key reason why the ‘bits are bits’ mantra never stacks up. The review is also significant as you’ve brought the analogue v digital debate into clearer relief. No way can I afford the mscaler, but I can get some of the benefits using the HQ Player software from Signalyst. Maybe review that, even though it isn’t hardware?

Nice and informative review of the M Scaler. I got the TT2 first and it was great - so much better than the original Chord Hugo I had purchased and used since 2015. Still, I just could not resist adding the M Scaler a little afterwards and I'm really happy that I took the plunge. It's another major investment on top of a great DAC/preamp/headphone amp like the TT2 but definitely worth it. There's definitely more clarity to everything but, as mentioned in the review, also smoother. It's as if all the little jagged edges around the notes and the sound are smoothened out. It's hard to describe but it can be likened to putting on a new nice pair of glasses that lets you see things much clearer and in more detail. The TT2 and M Scaler combo is awesome. It's certainly the endgame system for me. I know there are more expensive DACs and other audiophile stuff out there but I know I won't be spending another $10K or more to 1% of a difference in "improvement". I added the Chord TToby power amp to drive a pair of Buchardt S400 speakers to round out the system and my headphones are the LCD-4 and Susvara. I'm still dreaming of the AB-1266 Phi TC but that will have to wait. I can only splurge so much at once. Haha. But, man, the TT2 and the M Scaler are the heart and brain of this system. Once you have this, then you can build more around it anyway you see fit. When I play the system for people, they are just awestruck and can't believe what they are hearing - through the speakers or the headphones. My wife's comment was: "I guess we won't need to go to concerts anymore."

Chapeau, again. Thanks. And a test track tip for room acoustics: my heart is in the Highlands by theatre of voices. The creator spiritus album of Arvo Part compositions. Only good dacs don't throw the different registers of the organ all over the room. Left to right, front to back and even in the vertical plane. And they don't make the singer sound like it's dubbed over the recording.

I normally use my M Scaler with my Qutest, but I tried the M Scaler with my Singxer SDA-2 DAC/amp and indeed heard a benefit from the M Scaler with this lower-priced DAC.

Thanks!

I have loved all the chord reviews recently. Is this the final one in this series?

Great review! While I have not tried with any Chord products I usually find the difference between ASIO and WASAPI down to the driver mode. Rather than Event mode try use WASAPI push and it should sound like ASIO.

Definitely feel I got the jist of what you were saying. Great devices, definitely are devices I'd like to demo 😃👌🏼 hoping we have CanJam in Chicago, next year 🤞🏼😅. But we'll see..But great review!

I know Rob Watts provided his opinion in the interview but I was wondering if you were able to test the m-scaler versus upscaling with Room. Would love to hear about your experience.

This is the best explanation of the timing correction mechanism and effect that I have heard. I added the M Scaler to my Bricasti M1 SE DAC and results were a significant upgrade in sound quality and enjoyment. Even limiting upscaling to 4x can result in a substantially enhanced illusion of being in a concert hall or recording studio. The improvement to tone is an even more consistent improvement across music files. Nice review.

My takeaway from your excellent attempt at explaining the M-Scaler, is that it makes a better guess (which seems the most it can ever hope to do...?) at the original waveform. Hope I've got that right! On a different tack, is the M-Scaler supposed to be kept powered up for best sound, and how much juice does it consume? From the specs the power supply is rated 15V @ 4A, so a max output of 60W. Like many hi-fi components that come with a wall wart it doesn't seem to have an (on/) off switch -- encouraging us to do the opposite of cutting our energy consumption. Everything in my current setup has either a mains on/off switch, or very low (

Oh man a qutest, pontus shootout with bonus ending adding the mscaler at the end would be amazing!

Thanks for a review. I felt same listening to m scaler. There is one thing though, why you have not mentioned that portable Hugo2 Chord dac can also benefit same way and same resolution as qutest and TT2 just not by BNC but DUAL COAX. I had this test with my Hugo2. Works well at 768khz. Please make a review if possible of Hugo2+Mscaler versus Qutest+Mscaler. They sound different. Wondering how you would describe that. THANK YOU.

great review, wondering if you ever had the chance to try out HQPlayer. It can hit a sample rate of 1.5M. I just connected one to my Holo Audio may and the sound is jaw dropping. Would love a comparison of the M-scaler to HQPlayer

16:29 for sound evaluation. I'd recommend listening to the entire video, but I often come back to listen again since there's so much good info in these, so thought the time stamp could be handy to others, too.

It's great for you to review a product like this given its price tag and its very niche role in an audio chain. I need to ask though if I wanted to improve my audio experience, given its $7800 AUD price tag would it be more worthwhile to instead buy Burson's flagship Conductor 3X GT ($4000 AUD) or a Susvara ($7500 AUD)? I'm asking because I already have Audeze's LCD-5 which is regarded as being in the same tier as the Susvara, while for my Amp/DAC I use Burson's Conductor V2+ (discontinued) which I subjectively think sounds excellent with my LCD-5 with tons of power/headroom. My question really comes down to with a budget of up to $8000 AUD, should I: 1. Buy an M Scaler to use with my current Amp/DAC 2. Buy another top-of-the-line headphone like the Susvara 3. Or instead upgrade my Amp/DAC combo and get Burson's flagship Amp/DAC whilst saving $3500-$3800 in the process?

Sounds like a nice piece of kit! Your right. I don't get why you get a cheap plastic remote and a switch mode power supply at this budget. Like the qutist dac having a similar switch mode power supply , a better linear improves the performance of the dac. Guessing same with the mscaler. When your reviewing dacs and combos at this level it would be nice to hear about comparisons that are in similar ranges. Perhaps a chord Dave or the dcs bartok with headphone amp. A bit more expensive but it makes its intersting from a "value" perspective in this league. With the dcs you get a preamp, dac, streamer and headphone amp of all great quality. A potential to really decrease the box count for those wanting a simple end game setup. Their are other dacs playing in this $10k area as well. Darko did a mola (spelling) dac similar to the Bartok for even less $$ and even less than the combined mscaler and tt you reviewed here. Just throwing out ideas for future content. Terrifc professional reviews as always!

I currently use a Qutest dac into a Rega Aethos amp into B&W CM10 S2 speakers. An audition of the M Scaler is next on my list. Do you think my setup is good enough quality for me to hear the benefit that the M Scaler might bring ?

6:03 that sounds EXACTLY like a technical explanation of Hawking radiation PBS space time did a while back - next level !

Great review. Quick question, do you use your TT2 and M Scaler combo with the stock BNC cables? Any advice on that? I am tempted to gram the M Scaler but don't want to spend hundreds more on cables.

I always thought it was something like the Powerman is to the Formula S from XI audio or the Hypsos is to the Oor for Ferrum audio. Then add on a DDC like a Gustard U18 or Singxer SU6. But really what it's doing is so much more than either of those.

you've got so many good gadgets! 😉

Thank you for the excellent review! I had recently purchased the Hugo TT2 and was curious about the M Scaler. Your review was very helpful and has answered a lot of questions for me. How does the M Scaler work with something like KZfaq videos? Does it help and is so how much and do you need to use the video mode of the M Scaler? Thank you, again!

Hi mate, thanks for your review. I've just recently purchased a Hugo 2 and your review, and many others praising the performance of the M-Scaler, has certainly piqued my interest! Any recommendations on interconnect cables which I can look into to pair my H2 to the HMS? I don't have the budget for the the TT2 and HMS, but I could certainly start saving up for the latter! Cheers

Great review, very informative. question, what brand of coax cables are you using between the M-Scaler and TT2? I ask because i have the DAVE and M-Scaler and have been testing different brands of coax to hear what impact to musicality or not... thanks

Hello, very good explanation of the technology. Do you know if the Mscaler can Bypass native DSD to the Hugo TT 2 without being upsampled to PCM if desired? Did you tested any DSD music upsampled to PCM as well? which option sounds better? Thanks!

I have watched the video all the way through and didn't really get the answer to the question: does the Qutest sound the same with the MScaler as the Hugo TT2 or does the TT2 sound better due to a better analogue output stage? As an owner of a Qutest I am wondering if the MScaler/TT2 is the ultimate destination or will the Qutest provide the same quality in combination with the MScaler?

This is an excellent review. I already own a TT2, which is terrific, although I always use it with headphones. As my best ones are Focal Utopias and Sennheiser HD800S, the reproduction is really excellent. I am awaiting an M-Scaler for trial at the end of this month. As most of my stored music (Qobuz and on J-River) is already hi res I will be interested to see if there is a noticeable improvement when upscaling. I also have a lot of stored music on my laptop in DSD format up to and including DSD512, mainly purchased from the Dutch site, NativeDSD. I realise that DSD will be converted to PCM. I wonder, therefore, whether owning the M-Scaler will have any bearing on my possible future purchases of music in DSD format. I happen to enjoy it, because I like small combo modern jazz and classical chamber and single or duo instrument music. Can I really expect the M-Scaler to improve the reproduction of my music in DSD format? Any thoughts, please?

Is there a more reasonably priced alternative to the M-scaler? Something that would make more sense budget-wise to pair up with a ~500-1000 USD dac, like Gustard A18/A22 or Schiit Bifrost?

How does TT2 plus M Scaler compare to Dave. For the approx the same price, which route would you take?

Hi there! I do not understand, when I use the Roon DSP function and do, for example, a scaling to 768 kHz, am I not doing the same as with the M Scaler?

What would you recommend that a D90 owner with limited funds should do first - buy the MScaler with a view to perhaps one day upgrading the DAC to the TT2, or get a TT2 first and the MScaler at some point if future? 😃

I have Chord Dave and was thinking about MScaler , I also think that with my Martinlogan electrostatic speakers I can notice mscaler speed , wish Chord Would create an Device similar to Mscler but in Chord Dave form facto with built in steaming line chord 2go 2 yu

Man maybe I should’ve gotten a Hugo M scaler first and paired it with my Hugo 2 instead of upgrading it to the Hugo TT2, like I did. Moon audio sells a dual BNC to mini coax cable to pair the m scaler to the Hugo 2. However, I was advised I would be better off getting the TT2, because my Audeze LCD-4z’s planar magnetic headphones would benefit from the extra power of the TT2’s headphone amp. I actually did see this benefit when going to the TT2. I saw a huge jump in low end power and bass across the board, when I upgraded to the TT2 from the Hugo 2. It’s hard to describe. Regardless, I desperately want to add the Hugo M Scaler to my audio chain! I pretty much exclusively us Qobuz for the streaming high res FLAC files. Would the M Scaler do well with a service like Qobuz, with upscaling the streaming FLAC files? Thank you for your time! As usual, great & thorough video!

I think I understand how efficient FPGA is, but I don't understand how much improvement would be against upsampling using RoonLabs or Audirvana to the maximum sample rate. Imagine I have sufficient cores in my computer and sufficient memory to do all the computation, buffer the data in memory and then serve it to my DAC. What would be the difference?

I recommend you have a listen to James Taylor singing "Gaia" from his Hourglass album. Wait until the drums come in!

It's not going to take a redbook limited dac and upsample to 192 though, right? Wondering it's worth for a vintage dac that was high end in its day and still sounds great today

Are speakers or headphones not slower then the m-scaler?

Can the m scaler be used together with the dcs Bartok?

I am finding the exact same ASIO issue and have had to switch to WASAPI in Roon because the second a Windows sound plays it claws back the exclusivity - something that ASIO is supposed to be able to retain by default. Did you ever resolve this? I emailed chord and heard nothing back.

Is there anyway to record the digital signal coming out of the m scaler? If so I think that would be a great for anybody to compare the differences

Do you Think the smsl vmv d1 is good enough?

Great reviews! I took my first dive into this incredibly amazing world about a year ago with the chord mojo and some JH Billie Jeans and ABSOLUTELY FELL IN LOVE. So I decided that I’m ready to take the next step sooner than later with the Chord Hugo TT 2, the Chord M-Scaler, and some new JH 16v2 Custom IEMs. Now my only issue is with streaming services. I’ve noticed more and more that songs I like are disappearing at random and I’m kinda fed up. I’ve done some research but I couldn’t seem to find any places where I can actually buy songs that I want to own outright. Do you know of any good places?

How does the M-Scaler sound with the Yggy OG

Tempted to stretch and get Dave but get the sense Dave is a handful to tame. So maybe tt2 for now and later upgrade with m scaler, which together is comparable to Dave. True, does all this make sense?

The fly in the ointment with the MScaler is that it is a (Chord) elitist piece. What I mean is that it isn’t possible to get the most out of the MScaler without a Chord DAC. Q: What do you get from the MScaler if you don’t like the Chord sound or want to try the MScaler with another-brand DAC? A: A fraction of the $5k MScaler’s capability. Other brands are using I2S to transfer high-bitrate data streams but Chord limits you to their proprietary dual-BNC. Other pieces use similar upsampling/DSP technologies. Most are Integral on high-end DACs such as MSB and dCS. One standalone device that is soon to be released is the AudioByte HydraHub. Try and get ahold of that for a review!

Great review but at that price point doesn't it make sense to just buy a DAVE instead of the MScaler and TT2

Hi, I have a SoTM SMS-200 Ultra Neo, tx-USB Ultra & sPS 500 power supply and a Hugo TT dac, would I get a better sound by introducing SoTM’s master clock (sclk-ocx10) or a Chord MScaler, your thoughts would be appreciated

I wish there was a way to make these differences audible on KZfaq. Maybe even by using pro microphones (or a binaural head) to record a set. You may not hear the quality of the original gear, but you will hear the relative difference.

14:25 why does it display 705 on dbnc thought it was 768 using dbnc?

is there any device similar to Chord M-Scaler but cheaper ?

Have you heard the Dave yet? How would you compare to HMS/TT2?

Hi! I have added the Mscaler to my TT2 - with Ferrum OOR and Hypsos as an amp . I noticed a drop in gain with the Mscaler in my system , to the point that with my ZMF Verité closed is making me think if I should now starting using hi gain on the OOR… like now with Mscaler a need 2 to 3 o’clock on the nob of the OOR in Mid Gain to have good level for listening . Where before the added Mscaler, always use 12 o’clock with the ZMF VC. Is this correct or is something wrong … ? Thanks in advance for the help !

Now I’m thinking ... TT2 + MScaler or Mola Mola Tambaqui? This hobby is nuts.

Thank you! I think you did an outstanding job explaining something rather complex and difficult in nature to grasp and present it in a way that is comprehendible. Now, the trick is where does the money come from to get this device! 😆 I have the original Hugo TT and not the Hugo TT2. What do you think I should expect pairing the M scaler with my Hugo TT? Would it be the same level of performance as with the HugoTT 2?

All I know is I like the M Scaler. It upscales all my 44.1 CDs to high res. Plus all my streaming. The DAC is getting 768k out of the M Scaler and the audio improvement is there, albeit it may be subtle depending on the recording but I dig it. The M Scaler is akin to the Darbee video upscaler if anyone is familiar with that. It may not actually add resolution, but it sure looks (sounds) like it does. Sorta like magic frankly.

Wonder how does this combo compare to Dave?

How is upsampling with this different from upsampling using the much, much cheaper Roon?

Can you review Fiio K5 Pro Dac/Amp ?

MQA or M scalar , which ones batter ?

Just ordered an M Scaler to accompany my Qutest...I cannot wait

What about adding the m scaler to an Amps internal dac?

Test track suggestion: here but I’m gone - Curtis Mayfield

What BNC cables are recommended?

For the exact same price of the M scalar you could get the Kitsume KTE Holo May DAC which beats the Chord DAVE with the M Scalar combined. :)

Chord Hugo to Chord Mscaler: what are you doing step dac?

I am to receive my Chord Hugo TT2 tomorrow. If it is better then my 32 year old Wadia 2000 D/A for my stereo system then I will keep. If I keep then I have to start thinking about the M scaler. Ouch. Did you ever purchase the M scaler for yourself, or is it just too much money for the improvement that you get with the combo?

So. TT plus mscaler or TT2? ◡̈.

Excellent and informative video especially the part how upsampling improves time accuracy rather than frequency range. One question, did you get the chance to connect it to the Holo Audio May you recently reviewed? (A pity the BNC out can only handle a maximum 192kHz rather than the minimum 256kHz recommend by science for perfect timing).

ASR reply..."Your investigations are arriving at wrong conclusions. 1. I tested all rates up to 16X. This is why I used Hugo 2 so that I could go up to that rate. Measurements show zero improvement in fidelity with any multiple. 2. There is massive difference between bypass and 2X/4X. The latter invokes the long tap filter. If those make no difference, then the whole logic of such filters make things sound better goes out the window. 3. I tested 2X/4X more because it is standard compliant so I could use my analyzer to see what is coming out of M-scaler. The 16X setting only works with Chord DACs and you can no longer perform any digital analysis of it. But again, 16X testing was performed in at least two of the tests. 4. There is zero excuse for any amount of jitter/quantization noise in a box like this. I can get a $80 USB to S/PDIF converter with less jitter than the M-scaler! It is like paying 100 times more for a car and having the door not close right. Yes, you can still drive it but it is no excuse whatsoever. Remember, people buy this box because they think Rob Watts knows what he is doing here when it comes to digital audio. Clearly that is not reflected in this device. 5. Wrong dither algorithm is used which dumps unneeded amount of noise in the signal chain. 16X mode uses noise shaping but for reasons that nobody knows, the same was not applied to lower multiples. This is just wrong design, period. 6. There is no audible difference whatsoever between bypass and 2X. Take a listen. If there is no audible difference, why is it even there? Think about this. 7. I feed S/PDIF to Topping D70s from my analyzer and it works perfectly. I then route the same signal through M-scaler in bypass mode and it damages the performance of D70s. The arrow directly points to M-Scaler unless proven otherwise. How do you know other DACs don't screw up the same way? Company is very clear that the M-scaler can be used with other DACs. Stereophile used a Mark Levinson DAC for their testing. So please don't say it is designed to only work with Chord DACs. It is designed and advertised to work with any DAC at 2X and 4X. 8. There is nothing in signal processing that backs improved audio fidelity due to upsampling. The information is gone forever once you go down to 44.1/16 bit. It is layman fantasy that if you manipulate audio samples, by magic you get better sound. The only thing a resampler can do is degrade which M-scaler does. At best, it does nothing. Company provides no controlled blind tests of any improvement. What a youtuber may or may not say matters nothing. If the box makes such a difference, then it should be walk in the park to show the benefit. Have someone change settings blind and tell me you can identify the M-scaler 8 out of 10 times. I say good luck with that. Try it with my blind samples. 9. Only in audio consumers seem so anxious to believe manufacturer claims with no objective backing. If sold bottled water that said causes you to lose 10 pounds a week vs others, would you believe me? I assume not. Why on earth would you search for reasons to put aside audio engineering, science and research? You may not know what this box does but many of us do. Read the comments in this thread from other engineers who are amazed such a box even exists. Let alone exists at this price."

Is this something like Hegel does with their sound engine 2?

This is quite possibly one of the most controversial products in hifi (that’s on the project plan for later 2021/22). I’ve been doing some research into the general sentiment and see 2 schools of thought, the measurement purists that hate the m-scaler, and the music purists that are looking forward to what it offers. Though, im not dismissing the centrists jn this duality. It definitely highlights a few things missing in the hi-fi community, especially the idea that measurements aren’t everything. It seems the m-scaler’s unique selling point is not just up scaling but highlights the psychoaural subjective aspects of music that sit outside of measurements. Eg. The effect of transients on the emotional experience, the sound staging, etc. im not saying the m-scaler is not measureable in an objective sense. it just really pushes the argument of “you just gotta demo it irl” and I just can’t wait to do just that and make my purchase!

Jj Lin - from me to myself. Shpongle - are you shpongled Ar rahman - meenaxi - noor un ala the breeders - Cannonball Linkin park - break it down 😂, yes I use it as a tester song for being able to see through the distortion and clipping. I think what you're trying to explain is - effortless/real (less harsh) when you try to mention smoother. 6.23 - not one million times. Infinite times. And Nyquist shannon theory is valid only if you have infinite samples - like music file of infinite time, since the very act of low passing will create ripples through to time infinity and then we need to convolve with a sinc filter of infinite precision ie infinite bit depth and infinite time again. Put simply the theory is a limit tends to infinity condition, in real world we can only try to trace an approximation of it. In a real world we use windowed reconstruction filter, whose side effect is spectral leakage which is highly non linear and hard to easily visualize. It's just that one million taps is a better approximation than a thousand taps, but you can keep pushing over and over and get better approximations even beyond a million taps. I'm pretty sure you got a lot of requests on hqplayer but I'm going to recommend you to try something a bit different. Go to this place called xxhighend (no it's not a porn website) and look into that software and their phasure NOS1 dac. Also hope you got a lot of nice mastered content in 24bit 192khz. web.mit.edu/2.972/www/reports/ear/ear.html

I think it would be interesting to pair an M Scaler with an NOS R2R DAC. The reason is, I believe the reconstruction filters in a NOS DAC are minimal. They are just joining the samples in a very basic way, but with the benefits of low (digital) noise. An R2Rbeing fed with high upsampled rate might be the purest solution (though not as pure as feeding the R2R with music recorded originally in high res, eg 24/192kHz+). Note the sinc function is needed to recreate the correct analogue wave form from a Nyquist 2x sample rate. The sinc wave form with its infinite ripples in time before and after the pulse sample, add up to recreate the original waveform. The following link is the best explanation I have found. chordelectronics.co.uk/wp-content/uploads/2018/07/The-theory-behind-M-Scaler-technology.pdf According to Rob Watts himself, the M scaler does not manage a perfect sinc function, but it is getting close. It is not clear to me how other DAC manufacturers, including ESS with their chips, are going about trying to achieve this. Thanks for your great videos

Finally the people at ASR have it to review. It’s a total waste of money and does nothing but add noise. You really need to make sure you no what your talking about, placebo effect is very strong with you.

I just ordered a Hugo m scaler to go with my chord TT2! What input setting do I change the TT2 to when using dual BNC?

Couldn't such upscaling be done on computer software level ?

If everything occurs in the digital domain, and it's running a well-known algorithm, why can't we just preprocess our audio files in our computer? For instance, we could run a script to upscale all of our 48KHz FLAC files to 768 kHz. The drawbacks I see are with live audio (videos) and storage space. The positives I see are saving money and running the algorithm 10 million times if we want to.

Thats normal with asio drivers.

Have you tried HQplayer's 1 & 16 million tap filters? A hopefully fresh few test track suggestions: Get Direct - Joan as Police Woman A Man is Not His Song - Feist Evil Dub - Trentmøller

Very very difficult to justify this purchase due to price and debateable wizardry. I would much rather go for a Abyss AB-1266 Phi Audiophile Reference Headphones rather than spending so much on a pre-dac. Good review though. Thanks mate, dig your stuff.

You will *always* only get an approximation from digital audio. Any time interpolation is applied to tie two samples together you are inventing data that isn't there. The data is the data. It's like the infinite zoom of CSI shows, where they "enhance" an image and get detail that isn't there in the original image. Sure, you can make a best guess of what should be there - but it will never, ever be 100% accurate. When the sample rate is high enough that you don't need interpolation at all - that's when it gets really interesting.

Yes it is getting very very close to an analog signal; possibly imperceptible. very cool.

Fantastic review....but I cannot hear it! All the time corrupting the original signal.

LOL. Voodoo device. 5000 euros here in Germany. For that money i can buy the most crazy NOS preamp tubes for years and have certainly more benefit for my chain.

One should use ASIO all the time, what ever program u're on. Use ASIO Link Pro Tool. U can't let the Microsoft thing, even at idle... it constantly produces dings & wobbles.

I have demoed the M-Scaler at Munich and listening a very good album like "Spleen and Ideal" from Dead Can Dance, this album from 1985 is a very poor quality recording and adding the M-Scaler in the chain is just mind blowing trust me, you will completely rediscover your good old recordings.

Digital outs for non-Chord DACs limited to Toslink or BNC. (Wot no USB out nor I2S over HDMI out??) That means four times oversampling at best for non-Chord DACs, because of the sampling frequency constraints of PCM over bog standard Toslink or BNC. Not great value for A$7500 really.

How does this differ from Roon’s upscaling?

Please try hq player

This is hilarious man. Do some research on the Nyquist Shannon sampling theorem ;)
