You are entering a mine-field here. Google on ‘audiophile network switch’ and read some more about the subject. Try to have an open mind in the flame wars you will encounter.
Basically there are 2 camps of opinions about this subject and (believe me) in both camps are highly respected people including engineers. One camp says it is complete snake-oil and the other camp says it is not. Also in these discussion the ‘highly respected’ engineers can get very upset with each other (to put it mildly).
I am aware that it is not just 1’s and 0’s because those 1’s and 0’s are transported in packets in a compressed/encrypted form. Timing and other things also play a role and not only the integrity of the data. That the solution can be found in a network switch is highly unlikely, because the network switch has no clue what data in the encrypted packets it is passing along, let alone how to recognize and optimize audio data. In good streamers/DACs with good clocks the data is buffered anyway and reclocked. The network switch is not the most logical place to do this kind of optimization.
A lot of manufacturers of these products make bold claims without scientific backup and without proper measurements. Also in most blind A/B tests people can not reliably here the difference. People claiming that they can here the difference almost never do this in blind tests and are likely suffering from a placebo effect (they paid a lot of money so it should sound better). The human mind is very good in deceiving us.
Also take a look at this
It’s time for some hard truth - YouTube
The manufacturer of the switch in the YouTube link above basically sells a standard DCom switch priced at $40,- as an ‘audiophile’ switch for around $800. Be very careful and critical and do your research. A lot of ‘audiophile grade’ switches are basically the same as an ordinary network switch but sold for ‘audiophile grade’ money.
I do not want to start (yet another) endless discussion on this forum (or on any forum) about the pro’s and cons of these devices, but my advice to you is ‘Thread carefully’ and don’t believe everything reviewers say (even if they are engineers). You never know if they are independent and objective or paid and subjective. Try to form your own opinion based on as much information you can.
I also want to add that you need a very resolving (read expensive) high end audio system if you want to here those differences (if any). My priority would be more in investing the money in better gear like a good DAC, better speakers or amplifiers.
Do with this info what you want. This will be my only post about this. In my experience this leads to endless pointless discussions where I do not want to take part in.
