Network Switches

@mikey8811  : update 

I tried my EtherRegen with and without opticalModule. No difference that I can discern. Not even sighted 

@thyname thanks for the feedback. I read other reviews and there are some folk who find the ER causing a loss of body and warmth and sounding too smooth and clean. If that is the case, I don't think it will work for my tastes. That is the impression I have had with other Uptone products in my system. I would put them in the category of "you hear more but may not like what you hear"
@david_ten thanks for the tip on the Japanese switch. That sounds like it will work for me. However, the price is staggering.

My experience has been different @mikey8811  but of course, that’s just a subjective data point. As with everything, nothing replaces your own experience, in your home, with your own equipment.

@mikey8811   You are welcome. Telegärtner manufactures Networking Components for industrial, commercial, and home use...which is reassuring. Pricing on these types of products is high.

You may also want to consider Waversa...their router- switch combo has separation for general internet and the audio side. Cost again is high.

I just purchased the  TCXO Audiophile Ethernet Network Switch - "Silent Angel" Bonn N8.
I haven't seen any others here using it but there are several good international reviews and the price was right compared to other audio playback specific switches I looked at.  I will try in the configurations suggested earlier in this thread by @almarg and let you all know what I think. It should be here before Christmas.
