Every review I’ve read about a dac with Ethernet and the dac I use with Ethernet has always sounded better with Ethernet, 2nd best option would be i2s, last would be usb. You don’t have to be a so called streaming audio specialist to know this.
Ethernet streaming
Many high end dac’s now have built in streaming capability via Ethernet. Is this a better way to go than adding a separate streamer to feed the dac? In my case, streaming Qobuz and using roon. Also have an Aurender dac/pre that wouldn’t be needed if dac only streaming was used. Wondering about the advantages and disadvantages of these two approaches. I’m sure this has been discussed before, but I can’t find it.
