There is some great info in this discussion, and not heated. In answer to the openning post question is that my experience has been;
- Replacing existing switches with better/audiophile switches can improve sound quality
- Minimising noise in each network device handling your audio data matters, and that noise is from power and ethernet transmissions.
- It is important to pay attention to and be careful with the way cable sheilding is terminated as it could affect devices differently.
- Audiophile ethernet cable can make a big difference, but are not always the best solution for a particular link in a network.
- You need a very low noise floor to hear the full benefit of some little changes
- Fibre optical and wifi can be very beneficial.
- Some audiophile switches may not perform as well as enterprise or managed switches. For example SFP+ switches are very good. This is a good read ...
