Relationship between Ethernet Switch and SQ

Well frederik, I'm sorry you feel that way.  Perhaps if I were more of a politician...  But I'm just a retired, cranky old engineer.  I know that I would struggle selling hot potatoes to Eskimos.  But you know, as an engineer I always worked with data and stood up for the truth- even took a hit in my career once by standing up for the truth.  So you see it is hurtful when you claim I am making false claims about my own personal experiences.  Most people on these forums, like myself are genuine and want to share our discoveries and experiences with others.  Sure, we need to watch out for that wolf in sheep's clothing now and then but they are quickly found out.  

you fit the mold of someone who’s close-minded.

Ad hominem attack...not a good way to make your point...this is what closes people's minds. 

The rest of this, on the network side, is audio bling, unless your streamer isn’t designed well to handle any electrical noise over its LAN port. And that is only theoretical.

Chris Stephens of DeJitterIt uses older and more accurate test equipment to ferret out noise that some say isn’t in there and gets these results. Scroll down to see them at the link. Also, see this presentation:

This has been brought up before by other members who use this product and the naysayers who populate this thread never chimed in on it when this was discussed.

Granted, it’s expensive, but it addresses what some say isn’t there and shouldn’t matter. Maybe some of the naysayers can contact GTT Audio and Chris Stephens, debate/discuss this with them, and get back to the members here and report back how it went. Maybe even do a YouTube video or start a webpage about it instead of trolling on threads.

All the best,
Nonoise

I’ve been deeply tracking audiophile switches for quite awhile, looking for lower cost alternatives to the Telegartner M12 switch which also requires special terminated cables.  I concluded:

1. Audiophile switches must be at least to the level of English Electric 8switch, and this switch is easily beaten by more expensive audiophile switches. Home improved switches like Cisco are not enough to make a noticeable sonic difference 
2. Unless you need a switch, this is only an option. The Sonic benefit can be minor- like upgrading a cable.  Often the $3-4k+ would be better spent elsewhere 
3. You need a very transparent system to hear a worthwhile difference such as very low noise floor components which are costly 
4. Audiophile switches benefit with a better linear power supply 
5. Adding more switches reportedly brings sonic benefits

So for most people, it’s better to spend their money elsewhere than on an audiophile switch.  YMMV

A lot of people really suffer from the Dunning-Kruger effect in this forum, also known as cognitive bias, or the less you know about a topic the more you think you know about said topic.
