Sound quality differences between NAS units

For me, the idea that "Protocol is based on TCP means that it is bitperfect at the end" is OK in an asynchroneous world, but how does it fit into streaming ?

Simon, you are a top level engineer : you know that TCP compatibility with streaming goes through buffer management. Youtube streaming is based on TCP. Fine. But how do we care about latency when watching a movie on youtube ? We don't. Because there not in the video world an equivalent of our top level amplifiers and loudspeakers (me : Karan and Tango).

Many people here have a hifi system which is like a Pleyel or a Bosendorfer : any error by the pianist is hyper amplified. There is no equivalent in the video world. So, OK bit perfect, but latency, jitter, etc... Maybe at the level of a micro second. Could that make a difference ? Obviously yes. I can't see any other reason.

Yes I can see one : psychology. My son is a top sound engineer, graduated from Paris Department of sound engineers in the national conservatory (http://www.conservatoiredeparis.fr/en/le...ervices/). And yes, he experienced professor changing a parameter, and everyone heard a difference. Till everyone realized that the changed parameter had no impact on the sound produced. Bitwise perfect, exactly the same. But again, one should not put too much on psychology.

What we should not forget is that the mixt of digital and analog is very recent in music (and elsewhere), and that there is still a lot to discover.

Fortunatly !
