Clearly audible through someone else's YouTube (heavily compressed) video... Not
I mean, through the microphone ADC, then youtube compression, then played through my laptop speakers I can clearly hear a little less "sizzle" and a bit more "analogue" sound!! o_O:facepalm:

I exaggerate, sure, but honestly there's so much in the chain you can't possibly attribute any changes you believe you hear to the DAC, not with certainty. That's not science that's just a lazy armchair experiment, I can't understand how people would purchase anything based on such tests..

Even if there are all other factors there is still a difference that you can hear ;) There are also another videos that you can hear the same difference.


Again if you cant hear the difference good for you then just buy the cheapest DAC with good measurements and you are good to go.

No, you can't. That's the point. You're hearing random sounds which went through a very long chain of devices: DAC to be compared-> Youtubers' amp -> Youtubers' speakers in Youtubers' room -> Youtubers' microphone -> Youtubers' ADC -> Capture software -> Hopefully uncompressed audio file -> Youtube upload (audio compression) -> Your DAC -> Your amp -> Your speakers in Your room. That's ten (!) steps in between you and the DAC. Plus, you're listening to it sighted, not blind and you seem to be expecting to hear a difference. Apart from all of the points in this long chain where differences can occur unintentionally, there's the additional possibility that the person capturing the examples intentionally altered the samples to make them sound different.

I'm not saying there's 100% no difference between these DACs. I absolutely believe that they sound identical, but that's not the point: You 100% absolutely and without a sliver of doubt cannot tell if these DACs sound different based on a comparison through Youtube videos. You either compare them both in person, in the same room on the same system using a momentary switch to change the DAC, or your don't. Everything else is fantasy, not a comparison.

Or played with loudness in some parts. Indeed, all very good points you make :)

This YouTuber receives many products free of charge from SMSL, Sabaj and others. Consider that too. Also, he doesn't seem to be familiar with electronic circuits, so I don't refer to them.

What operational amplifiers are installed? The markings are not clear on the photographs.

I have an SMSL D300 and a Topping D90 (I know not a D30), both DACs measure superbly, but they do not sound alike. I connected them to the same amplifier, with the same brand and length interconnects. Both DACs where fed via USB by matching Raspberry Pi streamers running Ropieee. The content was provided via Roon and streamed to both devices simultaneously. The DACs where volume matched to .1 db; they were less than .5 db out of the box. In this configuration it was easy to switch sources quickly with very little interruption in sound and no change in the songs position and no pausing.

Now that is out of the way...

None of this is necessary as they sound very different. So different that I have no doubt even a bad YouTube recording would be enough to hear that they are different.

Try it. Go buy 2k in gear and give it a try. :)

Not sure if this is sarcasm. In the event it isn't: There's ample reading material on this forum on how to conduct a good double blind listening test and on why it is necessary for such a comparison.
