Why Digital Filterless R2R Dacs are superior over all other types?
In this video, we explore the fundamental differences between a digital filterless, non-oversampling R2R DAC vs the noise shaping, oversampling, delta sigma DACs. It is the reason why SW1X Audio DACs use a NOS (non-oversampled) R2R chip inside, making no compromise on the quality of sound of any recording.

The SW1X dac is the first dac I've owned out of many that makes me feel like I'm done searching for a dac
excellent. thank you for the feedback
What DACs have you owned, out of curiosity?
Just wait 😂
I would surely agree with this. Digital filters still add time delays. Wish these were cheaper..........i'd buy one.
Sounds like the typical pseudo-science, similar to people, who hear "digital steps" in the signal.
Full agree. Many people don't understand what the "steps" are -- and that a filterless DAC *has* those steps!
@@dougschneider8243 Their tweeters will act as low pass filter.
Very interesting, I have listened to several chip type DACs which have done nothing for me. I am unable to audition any model of r2r dac here in Toulouse which leaves me looking at speculatively spending 1000 euro or more on a DAC based on youtube reviews, which is a step too far for me.
Why not try audiophonics in France they have a return possibility in case you don't like it
@@bodhiveeren Thank you for very much for that tip, I was not aware of that
Rob Watts argued that R2R can never be perfect because the differences between resistors, what's your take on that?
Holo audio has already solved for this by implementing two ladders that compensate for each other.
The border patrol is an r2r dac and sounds wonderful.
Interesting to read the comments of people who probably never heard a nos r2r dac and only throw in the measurements argument too bad. They are to my ears and that's all that matters the most natural sounding DA conversion BTW I have an Abbas Audio dac that is similar in concept.
SWI1X borrowed that concept from Abbas hence the falling out the two had
I first heard an R2R DAC in 1982, so your statement is false, at least for me. They have no pluses over sigma delta, only minuses.
@@davidmasters1242 thank you david I am aware of that
He's talking about what Esoteric did 5 years ago with their new Discrete R2R DACs...
Not even close as exactly the same...
Not sure if this guy or the editor does not know what he is talking about, but someone is confused. First, anyone who has taken PDE should be able to write the proof that Fourier Transforms perfectly recreate the original signal, this is not "text book" theory, this is hard mathematical *fact.* Up-sampling does not create signal that never existed, and it does not affect the time domain. Reconstruction filtering *must* be performed, and it is always done in the analog domain. The editing makes it sound like on one hand he is saying it is evil, but on the other hand they do it on the analog output - which is exactly what *all* DAC's do. Noise shaping is an entirely different animal, it is always done in the digital domain. Without it, you will probably have the noise floor of the source as input into the DAC, so it is generally regarded as being a good thing, but it can have a huge affect on the musicality depending on the method. IMO, it is best done on the server side of things, and the DAC used with no input filtering. Not using it on streams or CD players will probably not be as good. Noise shaping will also have a major impact on the effectiveness of the reconstruction filter.
That’s not how DSP works. You will have significant aliasing and other non linearity issues without a reconstruction filter.
Assuming the audio was bandlimited in the first place then aliasing won't be a problem. What will be a problem is high frequency noise which is not being filtered out and which was NEVER in the origional analog signal that was recorded. These people should go back to school and learn about Nyquist sampling theorem.
Another voice lacking knowledge in digital
Yeah, let's throw a bunch of inaudible high frequency garbage into the tweeters to make their voice coils nice and hot 🔥
hahahahah funny!! but there's output transformers in this product. AKA low pass filters..Einstein..what does a low pass filter do? tell me...Einstein!?!?!
Sounds nice, pity their website is completely devoid of prices.
Their products are priceless. 🤓 Meaning free. 😆
Sounds like Audio Note Kit Dac's approach.
yeah, buy a kit and make it yourself
@@jungtarcph My OTL monoblocs and a single ended Class A, stereo OTL, amps, as well as several preamps, are from Transcendent Sound. Kits that are quite remarkable. I bought an Audio Note kit dac and am quite pleased as well.
I think you're right to take this way. But is not possible to hear that in comparison . There is no dealer here in Germany. Only distribution,- this is not conducive to sales given the high prices.
They have chip dacs with no filter option .. smsl su = x .. 😊
Tube output stage might get rid of the digital glare.
Nope. Good tube amps let all the good and bad come through including digital glare. Swap a polite sounding tube and you can mitigate some of the glare at the expense of some veil to the sound
Overdumbing with snake oil😂😂😂😂
Really ?? Omg .. Fuck dacs. Correct your room for acoustic flaws first. Then get a cheap chifi dac if that matters to you. Enjoy the music.. yaay
R2R is BS, my Schiit Yggdrasil was really inferior to my cheap Loxjie D40PRO, even my SMSL SU-9n did better 😛
Except that Yggdrasil is NOT a R2R DAC!
@@goodsound4756 If you can read dude => "The amazing Schiit Yggdrasil combines a state-of-the-art digital filter for perfect time and frequency domain response, then drives the output via an R2R DAC for a remarkably analog sound. Now with upgraded analog boards, Yggdrassil let's you say goodbye to "digititis" and hello to resolution, PRAT, transparency and incredible musicality." DAC chip: TI DAC11001B 20-bit D/A converters, look at the specs it's an R2R architecture.
Wild claims without evidence. It is so easy to measure a DAC. Compare the measurements between a high performance DAC with digital filtering and noise shaping and your R2R. The top rated DACs are inexpensive. If it "altered the time domain" it is easily measured. That would add distortion and harmonics and measurable errors. Talk is cheap. R2R DACs sound great for sure. You're not gong to hear a difference with those full range speakers in the background. All that cone breakup and beaming. Add a high distortion tube amp. Audiophiles are not interested in high fidelity. It's art collecting, and lots of fun, but it's not high fidelity. I guess you have to pitch something to sell a new product.
When DACs are measured, is this with simple sine waves? How about with a real music signal over time?
@@Coneman3 Yes, most measurements are not at all done with complex musical signals. Just go listen and buy what sounds best to you.
Nonsense. This guy cannot possibly be a signal processing scientist. He speaks like an amateur who has no formal understanding of the domain. The fact remains that commodity Delta-Sigma ICs beat everything your silly R2R designs can throw at them. Let's be clear : Even if a fraction of what he said had any substance ("the time domain", for instance) we are talking of resulting acoustic distortion phenomena that lie at the threshold of human hearing, if not beyond that loudspeakers or headphone drivers can trace.
I judge by my soul and ears ............and there's something realy WRONG with most digital, the best come only close to the real sound. But you're the expert .....
Bullshit.
In this video we find out that SW1X design does not have the first farking clue how digital audio works .... what a load of ignorant BS.
He makes claims but can't substantiate any of it as usual.
no measurements = no proof..godbye.
old talk....nothing new.
