The sound quality from DACs - is it all the same?


I've been talking to my cousin brother about sound quality. He is a self-proclaimed expert audiophile. He says that Audio Science Review has all of the answers I will need regarding audio products.

In particular, he says an inexpensive DAC from any Chinese company will do better than the expensive stuff. He says fancy audio gear is a waste of money because the data is already bit-perfect.  All DAC chips sound the same. Am I being mislead? 

He also said that any DAC over $400 is a waste of money. Convincing marketing is at play here, he says.

He currently owns a Topping L30 headphone amplifier and D30 Pro DAC. He uses Sennheiser HD 569 headphones to listen to music.  I'm not sure what to think of them. I will report my findings after listening one day! (likely soon, once I get some free time)

I wish i had written this sentence myself...  😁😊

 They don’t play with blind tests any more than the top birders in the world need to refer to google to make sure of the correct identification of a sparrow.

Sounds great according to them.

Unless they can statistically prove over a larger population that it sounds better, it don't mean jack. The ultimate approach in audio so far has been Floyd and Olive's at Harman, where they can predict with 0.86 correlation coefficient which speaker listeners will prefer in blind listening tests. And when bass extension is similar, that number goes up to 0.996. Believing anything someone or some company subjectively says without going through this kind of statistical scrutiny is akin to believing in get-rich-quick schemes. Unfortunately, the human psyche is built to want to believe in these kinds of schemes.

I highly doubt people buy their audio gear to statistically prove (satisfy) the mass population. I have a strong feeling they buy them to satisfy themselves. Not other people. There may be exception.

Again, I don’t think people blindly listen to what a company subjectively says. There may be exceptions. I have a strong feeling people buy their audio gear based on what they like and enjoy. Personal preferences. Commensurate with their budget / money outlay they can afford. Who cares about "Statistical scrutiny", and not sure whether the masses or a large group of "sample population" needs to have any impact on individual people’s decision to buy their personal audio gear.

Companies that produce really high end equipment are not unaware or stumbling around. They don’t play with blind tests any more than the top birders in the world need to refer to google to make sure of the correct identification of a sparrow.

I totally agree. They know what they are doing, and huge part of that is marketing their story. They know better than to try to compete in a lower cost market even if they could make products with their house sound for a significantly lower price. It would be as futile as if Ferrari tried to try to compete in the sub $30k new family car market. They don’t know how to do it. It ain’t easy at all! They could possibly team up with Toyota, but that would just tarnish their brand image, even if it turned out to be an excellent family car. The people who buy Ferraris don’t want to see the label on every low end sedan and mini van everywhere. The people who don’t typically buy Ferraris aren’t going to care much about that label. Making a car analogy is somewhat weak because a fast Ferrari easily has measurably better performance than a sub $30k family sedan. With audio equipment the "performance" as it might be measured typically doesn't correlate much with the price. So it's paying for taste, just like paying for styling on a Ferrari compared to some cheaper car someone has hot rodded so it's crazy fast. High end exotic cars typically get their special looks by having small amounts of internal usable space compared to the size of the car. Any practical design cannot look the same.
