Next best exponential DAC quality level?


I recently did a shoot out of three DACs using my Hint6 + routing each of the other DACs to analog input on the Hint6:

(1) Hint6: ESS Sabre32 -- Integrated 

(2) SMSL M500: ES9038PRO D/A   ~$400 

(3) Khadas ToneBoard(v1): ESS ES9038Q2M - ~$99

I played the same song passages on Amazon Music and was able to cycle through each Hint6 input corresponding to each DAC.

The result?  Very small difference in terms of rendering.  Maybe a more open sound stage with better overall balance using the Hint6 DAC.  The Khadas was more bass / midrange pronounced w/ a more narrow soundstage.  However, I wouldn't suggest that any were head-and-shoulders "better" over the others.  In fact, they were all pretty decent with only small nuances (certainly not worth the price differences.   

I decided to keep the Khadas for my small headphone listening area. 

But it got me thinking - how much would one have to spend to realize an exponential difference in quality?  Is the Khadas that good, or is DAC technology differences more nuanced than I originally thought (meaning, we're paying 10x for only 5% better).

@lordmelton , that was quite a feat to include so much "wrong" in a single post.

Here we go: A $99.00 DAC is a turd and you can’t put lipstick on it you probably have a better DAC in your laptop or car.

The $99 DAC has one of the best DAC chips made, the ESS9038, and yes that matters, because the chip does almost all the heavy lifting. My computer and my car most definitely do not have one of the same quality.

What makes a good DAC? Firstly it needs as good a signal as possible, so just sticking a computer USB into it isn’t going to cut the mustard.

Define a "good signal"? It is USB, and it really is "bits". The transfer is virtually every new DAC is async, i.e. the data transfer is completely independent from the audio output. That would be wrong #2.

If you’re using a computer you need JPLAY or similar to reduce computer jitter and provide drivers for the DAC.

Async transfer. "Jitter"on USB is meaningless and I don’t need JPLAY, I just need to ensure I have my setting correct. There are many good guides on the web for doing this. Wrong #3.

A big clean linear power supply is more important than what OP amps you use.

Perhaps you have not noticed the most recent Class-D amps, and linear amps using switch mode supplies and having performance better than just about anything with a linear supply? You don’t need a linear supply for good performance, you just need to know what you are doing. "BIG"? It is a DAC. They have fairly small power requirements. More important is ground loops and in most cases not relying on computer power, but not always either. A USB isolator is far more important than a linear supply. That would be wrong #4 and wrong #5.

The icing on the cake is a Word or Master clock so you can either slave your system to the Master or output separate Word signals.

Async USB, again. There is no "slaving" of anything. Except for the most cheap DAC implementations in your phone / laptop, external DACs will run a separate oscillator for the DAC, even that $99 one. Wrong #6.

Some good cables both digital and analogue will help enormously.

How will they help? Not hand waving. Very specific, how will they help. How will spending big sums of money, as opposed to say $10 or $20 for shielded cables make any difference? Again, not hand waving. That would be wrong #7

 

I do find irony in your accusing me of reading of Wikipedia but you don’t seem to have much understanding of how a DAC works.

 

@tsushima1,

 

Do you have a fiscal interest in the products discussed in this thread. I assume you do as you are just attacking me, but have not brought any value to the thread, and not refuted anything I have wrote.

Why do you feel the need to censor your fellow posters, and I don't mean me. They are adults. They can make their own choices about what they respond to.

Addressing the OP. I doubt you would find anything "better" than the SMSL  if it has the features you want and you're looking for a DAC that's not going to add coloration. If you're thinking warranty purposes and the hassle of shipping overseas there are US companies like Benchmark,  Bel Canto, Schiit etc. Don't get sucked into the rabbit hole of more expensive = better in DACs no matter what anyone tells you, even me. Find out for yourself, while not perfect try to compare them blind and level matched if possible or at least level matched. 

@cindyment  Yes you must be right because the Aries Cerat Kassandra II DAC weighs 120kgs and Lamm hasn't changed the design of their solid state 1.2 class A monoblocks for around 20 years.

These guys must be total clowns to build such garbage : )

Except there's plenty of people parting with $40k USD to buy each one.

I’m not liking the new poster and their forum flooding...their inability to show their name and face, and how they operate under false name after false name, etc.......but I do tend to agree with most of this.

At least as far as the surface ’take’ on it might be. But not with the superiority complex that comes down on from high, in a ’kindly dismissing of a child’ kinda way. A psychological victim of their own shooting from the bushes constantly, where they have lost their moral and ethical compass when it comes to relating with others on forums. The true self has been exposed, kinda thing.

Then we get down into the nuts and bolts of how to implement the chip and methodologies, etc -that are in question. And that is the part that separates the knowledgeable/lore from the book learned.

Which is the part that is not shared on forums, generally, as that is the money maker part for the given audio electronics production and sales enterprise.

When those aspects are well known and copied by everyone. This, if they understand it or not - monkey see, monkey do, china builds come to mind--but certainly not exclusive to china. When it is popularized in the DIY to professional world (best practices in dealing with audio electronics implementation for audiophile concerns) ---then it can be discussed more openly on forums.

The fundamental disagreements and arguments will always exist, though. As long as people are individuals and have different minds and physiological aspects from one another, this 'argument'  and all of it's giant sweeping tail of complexities in life ---will remain.
