Peace, brother @lalitk!
I fully accept that an external clock might improve sound quality. I don’t accept that the reason for this has anything to do with the accuracy of the clock. That’s all.
Think about or investigate what a streamer does. Its job is to repackage lumps of data into (effectively) a continuous stream of data. It completely reformats it and the accuracy of the clock in the streamer is important to sound qualiity (I used to have a Mutec MC-3 reclocker after my streamer); ditto the importance of clock accuracy in the DAC (I continue to use an external clock here myself).
I am happy to stand by my assertion that there is no possible mechanism through which ethernet clock accuracy affects sound quality.
