What is the best diy DAC? Looking for help and technical explanations

OT:

Panels are not for everyone: it depends a lot on the style of music you listen and the kind of rendering you're after (sure no box have it's advantage).
Another member here made the switch to meh and won't look back.

Limono why did you let the Weiss go? It was really nice converter.
 
Weiss wasn't mine. I had it on loan from a friend who upgraded to Denaphris Terminatir since it was all the rage back then. I liked Weiss better but with all personal drama going on could not afford to buy it from him and he could not justify keeping it so off it went. I look now and then for used units but living the life of a beggar now I cant splurge much on audio.. Also , I'm not less ignorant than everybody else here. Its just that Weiss was simply the least problematic digital thing I ever encountered back then. Simply out of the picture like a Raal tweeter .
It doesn't really matter what's best. It only matters what makes you happy ( for a moment at least )

...panel speakers are dead end of audio and dead audio in itself...
Really? Sound Lab? Don't think so. Speaking of John Curl, just got off the phone with him another very accomplished designer. One of them uses latest design Sound Labs as his top level reference speakers. Mine are a generation before, but upgraded with latest electronics. They are extraordinarily good as references. They make plain the quality, or lack thereof, of the upstream electronics. Don't shoot the messenger, even if they are only speakers 🙂

I'm not going to. Invite people over, play them some music and 3 minutes later everybody will start talking over the music and looking for snacks... Of course they will be delighted and say to you how wonderfool it sounds on their way to the kitchen table. Witnessed it countless times.
Audio and music are different things, I sacrificed half of my life for audio and I feel it was for nothing. What remains of it will be dedicated to music and for that almost any Jap midfi is absolutely sufficient. But it's not a topic of this thread.
Having said that I'm sure your stuff is first rate . Just don't do any demos competing against tape machines...
 
My bad. I was under impression that you work on commercial system. I'm not jaded, actually way too naive. Also, its a little bit of a crushing sense of defeat if it comes to audio. Assembling a great system is a goddamn trip and I simply realized I lack the skill. All the best.
 
As for the DIY DACs I would have selected the following ones:
  • IANCANADA Dual Mono ES9038Q2M DAC HAT
  • MarcelvdG Return-to-zero shift register FIRDAC
  • Andrea Mori's DSD-only discrete resistor dac

I have read very positive comments from users. Especially the first two on the list.
Now the question is which of these to start with.

Could someone give me a brief technical description of these 3 DACs? Above all, I would like to understand what the advantages and disadvantages of each DAC could be compared to the others based on the design choices.

Mine is just a couple of shift registers used as a DSD DAC. A logic circuit inserts a zero between each pair of adjacent data bits, then the signal goes into a shift register clocked at twice the input signal's bit clock frequency. The same is done with the inverse of the input signal, making it a differential DAC. The insertion of the zeros makes it a return-to-zero DAC, I've explained the advantages of that in the valve DAC article. Due to the differential structure, the current drawn from the reference is practically data independent, minimizing distortion.

It has an exceptionally low noise bandgap voltage reference, minimizing AM noise sidebands around the signal. I doubt if that is truly necessary, but considering the effort some people put into minimizing PM noise sidebands due to close-in clock phase noise, I thought I might as well build a decent reference to reduce the (typically much larger) AM sidebands.

Except for the suppression of these sidebands, I'm sure my DAC's technical performance is not nearly as good as that of any decent ES9038 DAC, at least not the distortion, SINAD and dynamic range.

I don't know what Andrea made, so I can't compare it.

I find that attitude weird, if not condescending. What is music? Is it pitch, harmony, tempo, lilt, dynamics, texture, tone, etc.? Is it only some subset, or is more than what is on the list?

What is audio? Is it an information channel, with music being a type of information? What constitutes the full dimensionality of what makes music be music and not noise or distortion? At what point does the channel become too noisy to convey enough of what makes music be music for the experience to be fully multidimensional?

Maybe its sad that for some people only a subset of what is makes music be music is all there is for them? Its like they are deaf to the full multidimensional musical information enjoyment experience. Sad, indeed.

Except that maybe what makes music be music is not exactly the same for any two of the billions of people on Earth? Maybe its that the subjective experience inside our heads is never that of perceiving true reality, just a limited and distorted internal representation of it? Yet that's not how it seems from the inside, is it? It seems a lot more like 'my' version is the most true one. Its like what makes music truly be music must universally be whatever it is that constitutes all that makes music be music inside 'my' head, and nothing more. Anyone different from me is sad, confused, ignorant, wrong, whatever?

I am talking about audiophilia nervosa.
It's the how it sounds rather than what am I listening to now or what do I would like to listen to.
It's when the entertaining or the cultural role of music has gone at the bottom and the habitual worry is if a flow of information passes only through communication channels of certain accepted quality.

Why the need to resort to a pejorative?
It's the how it sounds.
If audio is an information channel, and music is a type of information; and if this a more of an audio forum than a music forum; then what is wrong with people who as a hobby like to focus attention more on the channel that is audio, particularly while in this forum?

Moreover, why isn't 'how it sounds' a valid part of what makes music be music for some people? Does that not comport with your perception of reality?

George,

If I may I would like to explain something to you that might not know.

Last night I had the system sounding really good. There were three of my family here, and we were enjoying how real it sounded as an element of the music itself.

There are also some musical instruments here, and we have all been playing for a number of years.

There happens to be an acoustic guitar in the corner. The other day I restrung it. Why? Because new strings usually tend to 'sound better.' It can matter to a musician how an instrument sounds. If it sounds good, it can be more inspiring to play.

So, we put on Mile Davis, "Kind of Blue," proceeded to figure out the quartal harmony, and took turns jamming along. We have all been playing long enough to be able play expressively, to make an instrument sing, not just 'pluck notes.'

So, do think we deserve to diagnosed by you as suffering from a pejorative, made-up affliction, instead of being able to appreciate music?

If I have explained well enough, hopefully you are starting to see that things aren't necessarily as cut and dried as it may have first seemed.

@Jcris

Yeah. Pretty much along the lines of some of what has recently been touched upon over in the Black Hole thread. Some of the newer dacs measure well but don't necessarily sound all that good.

Regarding your link, now we can do substantially better at perceptual SQ than AD1862, although at the penalty of more cost and complexity.

It's a state of mind. I have the bug, I know the tyranny.

Wrong? It reminds me of the song "If loving you is wrong, I don't want to be right"

#35 doesn't explain it for regular folks and musicians have usually different mindset so what they say is of little if any value to a listeners. Very few people can switch off the quantifying mode while listening to the music. I can't that's why about the only time I enjoy music is when I drive . All other instances are about audio.

Sorry to hear that. Were you always that way? Also are you musically literate at all, IOW do you know/recognize what the music is doing? Do you listen to hear which instruments are being played, notice the playing style? Or is the only thing you know how to listen for the 'quantifying' of sound? If so, maybe that's the problem?
IOW when you are driving your mind is focused on something other than quantifying. When you don't have any other focus available, what's left but to quantify? You just want to become an empty vessel to receive the sound? If so, then you may need to learn how to meditate. Seriously.


Regarding listening while driving, I can listen AAC or even MP3 but won't listen satellite radio. Its not enjoyable at some point when the sound gets that bad.
Also, I don't think its about switching anything on or off, at least for me. Its more like an analog change in focus. Maybe more like a balance control.

Facts show that I belong to the hard switchers. Car driving and doing work at home is when I enjoy the music.

Mark, I see you take things personally and too seriously.
