Network Switches

@jason - very cute, answering my question with a question.  Since you choose not to answer my question I will answer for you.  Of course a switch that doesn't introduce RF/EM noise to a line can sound better than one that does.  You know this as well as I do. Every component in your chain that runs on electricity has the potential to add noise - it doesn't matter if the gear is transmitting analog or digital signals. 

Do you deny this?  And please, don't respond with another question.  A yes or no is requested.

Despite my attempts to educate people that if RF/EM noise introduction at the switch will really affect the audio signal, then after passing through hundreds or even thousands of interim switches and routers how do we even have a recognizable audio signal.

Another forgotten fact is that the switch does not communicate directly with the DAC, it communicates directly to the network card in the DAC and it's buffers, where the signal is extracted from the ethernet packet and stored until the DAC requests it.  These network cards are manufactured by a handful of chip companies and I guarantee that NONE of them are giving any attention to audio.  There is so much misinformation being thrown about here that it is disheartening that it's even being given serious consideration.

The only thing you are illustrating is your own lack of knowledge. I have developed quite a few products with Ethernet interfaces. Never once have I used a "network card". There are approximately 40-50 companies that make ICs with Ethernet interfaces. Easily that many that makes RJ45 jacks, ethernet transformers, etc., likely many that you have never hard of.

Your post illustrates a gross ignorance w.r.t. circuit design, whether digital or analog. That makes it pretty easy to pretty much ignore your posts as they are written from a position of ignorance, not education nor experience.

The rest of your post(s), just repeatedly illustrate you understand very little about what is being posted in this thread.

WOW!!! I finally got through reading all of the posts on the thread. I was avoiding tax filing work I need to tend to today. For once, I think I can honestly say I'd rather be doing my taxes. 😊

 I don't for a second think that RF/EM affects the audio signal! In fact I went to great lengths to say I don't believe it does at all.  What I'm saying is that the electrical powered gear - routers, amps, switches, etc can all introduce RF/EM noise into your chain whether it's riding the physical line (not the 1's and 0's) or just being in close proximity to other equipment.  Just admit it, power supplies etc associated with switches and routers can introduce RF/EM noise to your set up.
