If you feed a DAC with USB does XLR matter as much?


Does running XLR matter as much if you use a USB input from a streamer instead of an AES/EBU from a good transport?  Or, what about converting USB to I2S (my new DAC — Musician Pegasus — has an I2S input through HDMI)?  My preferred would be to just go USB into the Pegasus and XLR out from that to a fully-balanced amp, but wondering what I’ll be losing with USB input or what benefits I2S conversion might bring.  Thought I read both USB and I2S were the preferred inputs on the Pegasus, but I could be wrong and welcome other thoughts/input.  My guess is converting to I2S would be best, but that’s gonna require more $$$ and not sure how much added benefit I might get from it.  Thanks!

@auxinput Yes you are correct it's not set in stone which DIGITAL INPUT sounds best it's up to experimentation and cables etc., but the OP seems to think that inputs have an effect on which output cables (interconnects) to use.

They all go through the same output so it's not valid.

Got it.  Digital input independent of output.  Sometimes it takes me a while, and thanks for your help!  Still not sure if I should bother converting USB to I2S, but I guess that’s a subject for another day. 

@soix  Musician DACs recommend that you use XLR analogue outputs not RCA.

If you are using Computer Audio then USB will be your only choice for a digital input unless you put it through a USB/I2s converter, which I can't see being a great benefit as opposed to pure I2s but very few sources output I2s. Good luck to find one.

So if you have a streamer or cd transport try the other inputs they may sound better.

Good Luck.
