The Devialet DAC is going to be a constant. Where could differences occur? People report differences between ethernet, USB, AES/EBU, coax, optical, and wifi sources. Some of those differences are due to the fact that not all of those inputs can accept streams of the same resolution. Another difference relates to the clocking of the input stream which can contribute to jitter. Another potential point of difference is whether the DAC is galvanically insulated from the source of the stream, at least as far as electrical noise travelling with the source. Wifii and optical don't involve an electrical connection for the stream so there's a level of galvanic isolation there that copper wired connections don't have. There's issues with the source streamer with reports that different streamers do sound different.

Will there be an audible or measurable difference? There could be but it's going to depend on which streamers you compare, whether you connect them to your Devialet via the same method (not all streamers have the same output options) and, when it comes to measurements, whether you can compare the same measurements made in exactly the same way with test equipment of the same accuracy.

So, you may notice a difference but if you do, then which is better? Different people like different sound presentations which is why some people use Devialet amps and some don't, and why not all Devialet owners use the same streaming device or connection method. Even if you can find someone who has compared two or more specific setups that you are interested in, there's no guarantee that you and they will prefer the same combination over the others compared.

The question is never really about whether there will or won't be an audible or measurable difference. The first question is always whether you can hear one and, if you can hear a difference, then the second question is which one you prefer. You're the only person who can answer those 2 questions, no one else can answer them for you.
