Ethernet Switch- what's the point?

Actually it is not the case as the Ethernet run is less than 8 inches. Also signal in fiber into my house (frontier) and the 50 feet from the termination in my On Q to my listening room is all fiber. I have 8 inches of ethernet my listening space. 

Also find it interesting that the folks a WBF find this is very beneficial also. Different audience and more receptive.

I think you nailed it.  Converting to digital and back may add more noise than the fiber prevents.  

Or perhaps just shove off?

This is the Q&A I sent to Bluesound, answered by a ’Technical Analyst - Level 3" Scroll down to the end but it seems streaming audio is sent over TCP which I THINK means bit checked packets which if true, is CONTRARY to what I "learned" on this forum.

Question:

I have the Node 130 and mostly stream using Qobuz.

I’m reviewing my modem, router equipment and have a question about streaming protocols.

Does audio data transport to the Node via HTTPS/TCP (so bit checked packets) or a continuous stream using some other protocol?

Answer:

The ports used with the Bluesound Players are as follows;
Required TCP/IP:
· 80 (HTTP)
· 135 (SMB)
· 139 (SMB)
· 1025 (SMB)
· 445 (CIFS)
· 3400 (UPnP incoming events)
· 443 (Rhapsody, Napster, and SIRIUS Internet Radio)
· 4070 (Spotify incoming events)
· 3689 (DAAP for iTunes Sharing and AirPlay)
· 5353 (mDNS connection to mDNS responder)
Required UDP:
· 136-139 (NetBIOS)
· 2000 (BluOS® Proprietary)
· 1900 (UPnP advertisements / device discovery)
· 1901 (UPnP m-search responses)
· 2869 (UPnP connection to Windows Media Player 11 Network Sharing Service)
· 6969 (Getting Started process)
· 10243 (UPnP connection to Windows Media Player 11 Network Sharing Service)
· 10280-10284 (UPnP connection to Windows Media Player 11 Network Sharing Service)
· 11000 (BluOS® Proprietary)
· 11430 (BluOS® Proprietary)
· 5354 (mDNS connection to Bonjour)

Most times, in fact almost all the time, you won’t have to open or forward any ports for our products.

The only exception is enterprise installation, but Bluesound is strictly designed for commercial installs and most routers can handle our product’s required protocols.

The only issue that we see often are routers not supporting Multicast/Unicast which is how our app "locates" players, as without this... you can’t see or use the device.

Streaming on our players operates the same as when streaming from an app, as the stream is sent over TCP for our players to receive the stream.

To answer your question, as you are going from your router directly to your single streamer, a high end ‘switch’ may not be necessary. I had the same question, and was advised to get 2 Media Converters, tethered with an optical connection : Router > 1st Media Converter > 2nd Converter tethered with optical > Streamer.

This helped to ‘strip’ unwanted noise from the router, and indeed sounds better. All in? About $100 via Amazon. I’m pleased with the SQ increase.
