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,

AES sounds more real and incisive than USB to me; and I’m using high end USB cables and Innuos Phoenix re-clocker between a Bryston BDP 3 player and Holo Audio KTE May DAC.

I had a Music Server with I2S and USB out,  the USB was better.

USB has gremlins and is hard ($$$) to get right.  My current Innuos Music server has  renowned USB re-clocking but I use a DDC to convert to I2S as it is the preferred input on my Terminator DAC.

It can be hard to compare as the USB cable and I2S cables are different and have a profound influence on what you hear.

There is no one-size-fits all. It depends on the DAC, the streamer, and most importantly, your sound preferences.

 

From my personal experience of ownership, at least two examples when the USB input of a DAC sound better to my ears than built in Ethernet bridge: 1) Ayre QX-5 Twenty, and 2) MSB Discrete ProISL USB module
