- Welcome to Pursuit Perfect System Video coverage of the Nintronics Chord Electronics open day in November 2018
In this video Rob Watts continues his talk about the ideas and reasons for the technologies that he uses in his DAC Designs - in part 2 he focuses on the M Scaler. technology and why 1 million taps is so important for digital audio

Thanks for turning on the taps to this otherwise private event.
good job Dan "tapping" into my joke :)
@@PursuitPerfectSystem I just wanted to share my experience. I owned chord Dave and M scaler but I was shocked that I didn't enjoy the sound that much. Maybe I had too much expectation but I did like the tt2 and m scaler together. But I felt the sound wasn't clear enough like chord Dave. The m scaler and tt2 sound punchy but it didn't have the clarity like Dave. Dave alone without m scaler sounded better to me and I preferred.
My plan is to use m scaler with another dac. I like clear and punchy sound for headphone. However, I was extremely impressed with audiolab m-dac headphone amplifier. In your opinion do you think I will be happy with m scaler connected with audiolab m-dac, just to get a little punchy sound. I thought the audiolab m-dac was very good for the price.
Thanks
My problem with all these is that we still don't have a super reliable way of recording the sound with such precision.
Yep you can keep getting close to what is there in the recording by having high precision reconstruction filters (physical realisation), less aliasing and whatsoever but the recording is still not up there with the real thing.
Wonder what rob thinks of the recording industry, more importantly what he thinks of binaural and transaural audio, captured in say, a Neumann ku100
This is a fascinating video. Thanks for sharing.
Nyquist theory said 44.1kHz is more then enough for digital sampling of sound for human hearing.
So why digital sound so unnatural.
Easy because the same theory also said you have to use infinite sinc function to recover sound perfectly.
What Rob was saying is how to make making Nyquist theory practical.
M scaler recover sound with sinc(1,015,808).
When most chip DAC only use sin(32).
Sony and philips back in 80s believed you can't tell any difference when they use sinc(8) .
What a joke
Interesting that Dave P has got more interested in music purchasing since he has developed the m scaler and really started enjoying older recordings .
Time to get saving then...
Concert amps produces their own noises, distortions like an acoustic instrument + concert hall + people : U have such a complex mix of different things going on in an amplified concert. So no problem ur DAC has a lot to work with, despite music comes from limited amps.
I rate Rob Watts and I love my Qutest. I did however raise an eyebrow when he said in this video "once you get used to the M scaler, you cant live without it"...my question is why does one need to get used to it? If only he expanded a little more on this. Would anyone know?
Once you are used to the clarity it brings its hard to go back to listening without it, that is what he means
@John Gian its better for your Wallet If you dont experience the m scaler.
@John Gian that one will Not dell this good in 5 Years.
Beautyful Aliasing behind the man.
12:19 "...you couldn't even do it with a supercomputer..."
So if processing power has been a limitation, why does it have to be done in real time? Given the dual bnc output is 768kHz 24-bit stereo, that's about 35.2 MB/s - not too different from video streaming or compressed video files. So you could happily store all your music (or at least your favourites) after M-scaling has been applied. You could fit 53 days of M-scaled audio on the current largest consumer hard drive, which costs a fraction as much as the M-Scaler. You could probably use a fast lossless compression algorithm too, making it easier to store and transfer.
And being entirely in the digital domain, it doesn't seem absolutely necessary to have dedicated hardware for the hard work processing the audio. I'd be happy to run the maths on a suitable CPU / GPU that I already own - even if it can't manage to do it in real time, or with optimal efficiency - and store the output for future playback. Besides being a cheaper option for consumers, it would be immensely helpful as part of the R&D efforts - want to hear a 2-million tap length? 5 million? Try out a tweak to the algorithm? Just leave it processing overnight and compare it in the morning.
Mr. Watts is an amazing sales engineer
if you get a chance to meet him you will soon see he is an engineer not a sales man. It's easy to be passionate about your work when it's good :)
Pursuit Perfect System 100%.
I know yet more company that pays a lot of attention on sending their architects to different conferences. This is Airbnb. And they experience serious issues not only because of pandemic, but because it's hard to find their architects next to their working places. The application is bulky and buggy, fees are cosmic, and so on.
If this chap's University digs hadn't been so close to the psychology lab, I'd be a lot less confused right now... :)
I own the Qutest that has 50,000 taps. By using the M-Scaler (that has 1 million taps) in the chain before the Qutest, will there be problems or downsampling?
Hi Jim - the M Scaler improves the Qutest by a significant margin for clarity and sound stage - there is no downsampling to worry about ;)
@@PursuitPerfectSystem Thanks Terry. I would hate to be without my Qutest and now I really want to demo the M-Scaler.
Nearly 40 years in...digital is hitting it's stride.
how crazy is that ;) what's wonderful is if the source gets better then kit should start getting better to keep up :)
We have to be grateful to have access to this tech within the realms of normality and be thankful it's not exclusive to the uber hugh end
Saying that, I'll be picking up a pre-owned DAVE in about 10 years :)
mag 1981 same probably xD
Pursuit Perfect System yeah like graphene speakers connected with aerogel insulated cables ;)
@@mag-wp6yt When the Dave mk 6 has 10 million taps.
Does anyone know what the speakers are in the system he has set up?
they are the YG Acoustics Sonja XV Junior about £300k
@@PursuitPerfectSystem Crikey - that was quick! Thanks very much.
@@PursuitPerfectSystem I just read that again. £300k!! Probably a touch out of my price range then! (Not that I thought they looked cheap.)
@@barrymiller3385 They look cheap as fuck
All the theory doesn’t mean anything, if it doesn’t sound right!
The dac is just the digital to analogue conversion - the cleaner and better that gets the more of other things you hear as they become clearer - its important to point the finger in the right direction in audio which is not always easy as too often the new product into the system is blamed even if its not the limiting factor of the system,
No idea what this video is about .
this is the second half of a lecture by Rob Watts who is Chord Electronics digital product designer. He is talking about their new Hugo M Scaler / M Scaler technology and explaining why it is special. Its quite technical but if you watch it a few times there is a lot here to learn :)
crap recording and tech speak.. this guy completely turned me off Chord
Stephen Charlton Hmm how good does the recording need to be to listen to the tech talk ??
Of course its tech speak. Its a presentation. Rob is not a Sales guy. If anything I would have liked it to be more technical. If you want something exciting, look for a promo video or something.
