Relationship between Ethernet Switch and SQ


This one will probably invite some withering mockery, but I will ask....

I only stream, and my streamer (Bryston BDP) is fed with an ethernet cable that runs back to my router.  Literally back to my router; there are enough output jacks on the router that I have a long run to the streamer and no ethernet switch in the chain (or the house system for that matter).   (There is an Eno filter right before the streamer).

I happen to OWN a nice LHY ethernet switch.  I am assuming that there is no reason to use it in this configuration, that is, assuming there are noisier switches, and less noisy switches, there is still no net benefit of adding any switch to this chain.  But maybe, just maybe, in the metaphysics of electrons that I do not understand, there is some reason why a nice switch prior to the streamer accomplishes something (in theory...I get that I can A/B test and try to fool myself whether I can hear a difference).  For the first person with a correct answer, I will mail a nice $600 switch to the address you specify!

And here's one on the Aruba:

Like he says, you can get the Aruba, used, over at eBay. Just make sure it's from a seller with great feedback. There's tons of them online and you can scoop one up for $15 or go for a brand new one for $125. 

Also, make sure it's IAP 225-US so it's configurable and legal to use.

No need to spend $3K for the one sold at GTT Audio but you'll have to source your own linear power supply and it won't have any of the mods in it but you'll be way ahead of the game for pennies on the dollar.

How am I not an honest broker? Point to one post where I wasn't able to back up my statements or claims.

You said a long time ago in a heated debate that until anyone smarter than you shows up, you're right and everyone else is wrong. That speaks volumes about your mindset. Something tells me that someone like Chris (dejitterit.com) is smarter than you and you're afraid to actually talk to the guy for fear of being shot down.

As for you claim:
In a residential setting, there is no RFI propagation through Ethernet, it is impossible. 

I googled RFI on ethernet and got pages of all manner of people discussing it and how to get rid of it. Lots of them are engineers, radio operators, etc.

@nonoise  no, that is not what I said. I said I know more about networking on this forum than anyone else. And so far this holds true.

Provide a link and I will explain why it is not relevant.

@nonoise  ok, so first of, Microtik is a low end manufacturer that does everything in the CPU.

Then he says it ground canals on the circuit board, and that is complete wrong, you don't run ground from the SFP to the CPU, you run it to the ground. 

Continuing - he says "electrical" jitter. There is no such thing. Does not exist, just made up to sound good I guess?

The reason it is "clean" is because it doesn't use FPGA, everything is run to 1 CPU.  It's cheap designed, but for home use it won't matter.

Then he goes on and says that it is 10GBit chip, powerful and then says no one talks about the chip. Well, most modern designs don't use a CPU, they use FPGA, and then he talks about the throughput, yeah, every single switch worth its name is talking about it in specs, and not just jumbo frame throughput, but small frame throughput and frames per second.

he is however right about the more powerful the CPU is, the less jitter it will introduce. However, this is one of the reason why good switches don't use a CPU, they use FPGA.

Then he goes on a rant about double regulated voltage, also bunch of made up things. It does not improve stability of any component because it can handle two separate voltages. In fact, most higher end audio equipment like my Classe stack does the opposite to have more pure operation based on the voltage you use. So opposite of what he states.

"Dedicated ethernet port and dedicated isolation gadget" - oh my, where do I start here??? All made up again, according to the manufacture again, it's a LAN management port chip, nothing to do with isolation, link below.

So, there you have it. Another "audiophile" switch debunked!
