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 spoke for people like me with very limited budget...

@mahgister , A lower cost dac will benefit a lot from certain types of tweaks, vibe isolation, usb filters (IFI, audioquest, etc), ethernet filters, better power supply, power filters, cables, dedicated power lines and so on....If your overall system infrastructure tweaks are up to a certain certain standard, you can narrow the gap a lot between lower priced dacs and higher priced dacs. The higher priced dacs don’t benefit that much from above such tweaks perceptibly. If you understand circuit design/and are handy, you could tinker with some components in the output stage and so on...

Reviewers exaggerate differences they heard between dacs at different price brackets. It is a lot more subtle than what these guys claim. Guys in untreated spaces with poor or restricted setups (no distance between speakers/frontwalls, listener/backwall, etc) have already nullified most benefits of higher end dacs...might as well work with the room, i.e., get other fundamentals right before coming to the dac.

😊I think exactly the same as you... You said it well...

My two different main dac are relatively low cost but i optimized everything around them and especially put them where the synergy is good and upgrading is meaningless for me , it will be marginal and very costly... I do0nt even dream it because it appear meaningless acoustically ...

I own a Nos TDA 1543 dac , and an Hidizs dac ; each one with battery internal...The NOS one with my active speakers, the most analytical one with my headphone...All is perfect...

I have owned several different Dacs with different setups, but I often wonder about the question at least at a theoretical level. I currently have Holo May Kte which is very good sounding Dac. It is non over sampled R2R DAC which also has impressive measurements. I can definitely hear sound quality differences between DACs. However, these differences may not come off as obvious, meaning if you play a song with those DACs, you’d still hear that same song. If the music is very well recorded, it would be more challenging to decern any differences. However, DAC that sounds good to my ears has little or no listening fatigue so that I can listen to it for hours. I had Chord Hugo 2 and Mojo 1 & 2 previously. Imo, Rob Watts designs some fantastic dacs and these chord dacs produced really good PRAT. But, there were some unnatural characteristics with the sound that made me to stop listening after an hour or so. After Chord dacs, I had Moon 390 DAC / streaming preamp. It was an all in one unit that performed well, I thought. It had tad less detail than Hugo 2 but it definitely threw a bigger stage and deeper depth. The Moon sounded more natural to me so I had much onger listening sessions. Once I got May DAC, I could tell how inferior the sound of Moon was. From naturalness, tone / timber, and imaging perspective, the Moon DAC could not match.

Having said all that, I think about a perfectly converted analog signal which is in an absolute form. Any deviation from the perfect signal is an imperfect one. Knowing this, and DACs have compromises in their design and implementation, so I expect some variations of sound differences. However, these differences can narrow as they get closer to that perfect signal.
