What is a DAC and why do you need one?

[@GoldenSound]

A few important notes: 1) Whilst the video explained 1-bit delta-sigma and PDM at a basic level, most available delta sigma DACs are actually 'multibit' delta sigma. Meaning rather than modulating to high speed 1-bit, they modulate to high speed 5-7 bit as this allows you to avoid the biggest challenges with making a highly linear R2R DAC and you also don't need to be operating as fast or have as much difficulty with the modulator design as a full 1-bit DAC. 2) DACs that ARE 1-bit usually don't actually have a 1-bit PDM converter. Instead they usually use a moving-average FIR filter approach, this will be explained further in a future video. 3) Some products on headphones.com such as open box units may not fall under the 365 day return policy, please check the product page for specifics!

[@lunafag]

Strictly speaking DACs don't need oversampling. 16 bit signal -> 16 bit DAC -> reconstruction filter, no oversampling required. But when the DAC has less bits than the signal you need dithering to preserve the dynamic range, and when you need dithering it's a good idea to oversample to have less noise in the audible frequncies, even less with noise shaping.

[@zippymagee]

Excellent Video!

[@justuslm]

3:15 I just want to point out that oversampling isn't strictly necessary to reconstruct the analog signal. So long as you have a precise low-pass filter at half the sample rate, the signal reproduction will be accurate. However, oversampling allows you to control how that cutoff happens much more precisely. I don't know exactly how common DACs that don't use any oversampling whatsoever are nowadays, but you'd find them for example in toys that include a sound module.

[@GoldenSound]

This is true, though the problem is it's not practically possible to make an analog filter that'd do this, hence why we typically do it digitally as we can make a very steep filter that way. With an analog filter you'd either need to attenuate content in the audible band too much or you'd leave too much above the Nyquist frequency.

[@garfythecat]

That was brilliant!

[@AzDraon1]

This is a nitpick but I think Jetpack Joyride is a better representation of ΔΣ than Flappy Bird because Flappy Bird doesn't continue to go up when you feed it a continuous input and Jetpack Joyride is also very well known, albeit not quite as famous as Flappy Bird might be.

[@hartyewh1]

Spent most of yesterday comparing a Denafrips Ares II to a Topping E50. I was expecting to hear no meaningful difference or hopefully some presentation difference in the Ares. Before volume matching I heard all kinds of magic in the soundstage and imaging. Just like the reviews had said. By ear I was off by 1,5dB (on the Topping L70 volume scale). After matching things changed. No difference whatsoever in either, the bass was notably weaker or rounder on the Ares and the highs were easier, maybe smoother. I measured it and there is a treble roll-off. Around -1dB@7kHz, -2dB@9kHz and -5dB@15kHz. I EQ'd the same for the Topping and the effect was the same. In conclusion, I'd take an E50 (or E30, same thing really) over the Ares. Should have tested an Apple dongle as well which was about the same as the E50.

[@7in1]

Are you claiming that Denafrips DAC is having such huge FR problems that even you could measure them? It's hard to believe to be true

[@maximgodunov7717]

Hi. Apart from the tonality difference and dynamics, you will most likely not find any difference in dacs using easy to drive headphones or especially iems. You will need a speaker system to notice it, or something like a susvara. That's why most dac reviews compare them using speakers. Watch jays iyagi video where he tested 100 dacs. Also, you need to test much more dacs for more experience to know what to listen to and where you need to pay attention.

[@hartyewh1]

@@maximgodunov7717 I've tested dozens and from the Apple dongle to Jotunheim there was really nothing worth of note when proper volume matching was done. In power amplifiers there are massive differences with the integrated DACs I've noticed, but I doubt adding room issues and degrading the signal helps with hearing the differences. Perhaps power amps strenghten the coloration or something. I also used an HE1000se which should be essentially as revealing as anything. The bass issues and treble roll-off are still notable problems.

[@hartyewh1]

@@7in1 Depends if one considers them a problem or desired coloration. Imo it's a massive issue. Volume matched single seating measurement from a headphone showed that and it matches my perception so I can't think of another explanation.

[@maximgodunov7717]

@@hartyewh1 I'm talking about standalone dacs used with speakers. They are way more revealing compared to headphones because they have low impedance and sensitivity. Can't head a difference in soundstage if they is no soundstage to begin with. This is how most dacs are tested by reviewers- take a look at Jay's Iyagi 100 dac video

[@7in1]

What DAC (r2r or delta sigma) is producing more true digital signal from original analog, and why?

[@MrSmitheroons]

Instructions unclear, I mortgaged my house for cables. (I have no money left for headphones, speakers, DACs, or even a source, but I think I'm getting the most bang for buck, so I'm happy with my purchase decisions. If I stare hard enough at the cables I hear something that sounds incredibly accurate and also enter a trance state that I assume is essentially achieving nirvana. 10/10 would go bankrupt again.) P.S. I imagine you can send a DC, full-voltage, strictly on/off signal to a speaker but that it won't necessarily sound good, unless you like square waves and/or what I'm boldly going to call "rectangle waves". Or maybe the sound of your transducer committing sudoku.

So if i take the audio from my monitor (xbox series x source) via 3.5mm to Y 2x Rca connectors into the topping e70 Dac , the monitor has already a Dac built in , so my dac reconverts the signals another time ? Hmm , I'm very confused , how it works

Why R2R is praised more than Delta Sigma, if both are nicely doing same job but different style, isn't there should be the same sound?

You can actually use one plugged in as a speaker and if you manage to not burn it out you will actually hear sound reproduction out of it. Same if you plug a speaker or headphone driver into a mic port and speak into it - sound will be registered, even if only at very bad quality.
