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!

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! 

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. 

No, he doesn't. He says there's a ground plane on the back side of the circuit board and then says that the channels/ canals) allow for discrete paths for each input to the chip.

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

He also mentioned "packet jitter" with "electrical jitter" and if you google electrical jitter there's tons of info on it online under that term.

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.

He never ranted. Anyone can view the video above and see that. Also, he said it's double regulated to handle voltages ranging from 12 to 57 volts and not just two separate voltages so doesn't it perform like your higher end audio Classe which adjusts to the voltage used? 

And yes it's a less expensive design using a CPU rather than a FPGA but no one is running thousands of threads simultaneously. That would be overkill. If you google 10 bit CPU you get lots of praise for what it can do. In fact, they go on to say it's overkill. You seem to enjoy damning with faint praise a lot as the unit is just fine for audio use.

All the best,
