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,

If you want to use USB get a DAC or DDC with an Amenero board. This will bring the SQ equal or better to AES/EBU.

It is such a close call using my Musetec 005 DAC with my Aurender N20 I cannot say which one is best only that they are different. Should get my new USB cable today so I guess USB will be better, I'll report back.

Before I got the Musetec DAC, USB was in no way comparable to AES/EBU.

@asvjerry Hi, as Mr. Prentice mentioned above, conversion must take place with Toslink and it's bandwidth is limited to 24/96 Khz. Wadia tried to introduce I believe AT&T Glassfiber, which apparently was good, back in the day..

Weiss have a very sophisticated glassfiber long distance cable but it's quite expensive.

AES/EBU and COAX generally have to use DOP for DSD but USB goes through no conversion for DSD, nether does I2s.

Toslink has taken out the dock and I'd hazard a guess that it's slot will be replaced by I2s.
