First, know I have fully gone to the Dark Side of internet switches. I started with a Etherregen with a quality LPS, added a SOtM with a quality LPS switch then the English Electric with a quality LPS. I clock the Etherregen and SOtM with a Mutec Ref10. I have the ENO Ethernet filter and several SOtM cables with filters.
My experience is more is better.
If you want to start slowly I would suggest the Eno Ethernet filter, you should hear an improvement and if not send it back and stop. From there a quality switch will bring another level of betterness. The switch is a sum of its parts but key parts are the clock and power supply. An off the shelf switch is not going to have a decent clock so don’t try it and its power supply will be noisy. An external LPS is going to lower noise and you should hear it.
There is a level of diminishing returns depending on the resolution and noise of your system. I am all in with streaming. I used to believe streaming (Qobuz) could never sound close to a CD or ripped CD. Now I know otherwise.
