Ethernet Switch- what's the point?

Streaming fonts is not the same as streaming music. 

Melco makes two Ethernet very effective network switches - S100v2 and the top line S10-X. The S100v2 can be upgraded by adding a linear power supply like a Plixir Elite BDC linear power supply. The Melco S10X comes with it's own linear power supply. As well, Melco's sister brand ADOT is a fantastic way to isolate completely your audio system's network from the rest of your home networking. It takes the feed from your gateway and converts to fibre, which you then connect the ADOT to your Audiophile Switch. These must be heard - people who say it all makes no difference are ill-informed. These products are distributed in the USA by Luxman America.

TCP/IP guarantees delivery 100% error free 100% of the time. No switch or cable can give you better zeroes or ones. Noise, if it exists, is introduced after the fact. Some streaming uses another protocol called UTP which does not guarantee packet delivery, but it is not used in any audio streaming I am aware of, and rarely used any more with video. Differences, if they are perceived, are either confirmation bias or analog perturbations further downstream due to DAC filter design, poor power supply isolation, or induced noise. 

As for the claim that 'streaming fonts is not the same as streaming music'. You are misinformed. At the network layer, wired, wireless, fiber optic, it is exactly the same in all respects. That's the beauty of TCP/IP, it simply does not care about the nature of the payload or the media over which the payload is carried. It delivers packets, error checked, retransmitted if necessary, packets irrespective of the payload. And audio, even 32bit X 384kBits/sec are not even remotely strenuous loads for modern networks. 

I recall how strenuously the "bits is bits' argument was made in the early days of digital. And we know how that played out.

@macg19 nope. Not at all. Qobuz, tidal and Roon use HTTPS, stateful and encrypted.
