Digital Audio Output Differences? Is USB Audio Really The Top-notch?


Hello guys,

So after some struggles between spending time in optimizing my PC audio functionalities and adopting a dedicated music streamer, I opted for the second one.
I purchased the Munich M1T by Silent Angel, given it’s good reviews in UK and Germany and Switzerland, I thought it wouldn’t hurt to give it a shot, but frankly speaking, the mainly reason was because the price fits my wallet more hahahah...

Anyways, so there are several digital outputs on its back panel, AES/EBU; I2S(HDMI), Coaxial, USB Audio, hell hahah, I have literally no idea which one is better or which can provide a special feature or something, I mean it does show that the USB Audio supports up to up to PCM 768KHz and DSD 11.2M (DSD256), but does that the higher the sampling rate, the better the sound quality? I just can’t make sure...

And if the USB Audio can provide the " best " digital sound quality, then why added other ports? Ain’t that just costing more on the manufacturing end?
Hope you guys can give some insights on this, or share some of your experiences, because this is the first time I saw an AES/EBU port on a audio streamer...

Best,

USB is fundamentally a different communication method from SP/DIF and AES. USB needs packet conversion, retiming to a bit stream… so that is a function that now falls on the DAC. SP/DIF are the same through different connection types. Optical is usually not as good as it has to go through a electrical to optical conversion, and then back.

USB is a new comer… when PCs joined in the audio arena. Typically DACs had no USB input. At first DACs did not support them… it is packeted info… not just a digital bit stream.

So, audio equipment popped up that only supported USB, then the USB input was added to higher quality equipment. Which is better is completely dependent on your DAC / source combination. Sometimes it seems that which ever is the higher quality DAC or source), but that doesn’t always work. I have a top quality streamer and DAC and it is really hard to tell the difference. I give the nod to AES.
