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!

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,

@nonoise who is the dishonest broker now? 

he literally says the ground is on the backplane, and you can see that what he is running his hand over is between the SFPs and the CPU, so he is says the ground is connected to the CPU. That is what he is saying. He likely doesn’t understand what he is saying however.

Give me one article about electrical jitter? Electricity is in the analogue domain where jitter doesn’t exists. Are you perhaps confusing electrical and electronic?

it was definitely a rant. And double regulated doesn’t mean that you say it does,. It means it can handle two different ranges, for instance 200 - 240 and 100 - 120V. And he says it makes the component more stable, which it doesn’t.
 

a switch literally handles thousands of parallel threads per second, it is the only job of a switch.
 

And @nonoise, what about his ludicrous rant about isolation gadget? Pure fiction.

So, now you have proven yourself again to be a dishonest broker, for what?

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.

keep in mind that all communication devices are regulated by the FCC, and while they are not likely to care if you modify a switch as the worst case scenario is that you burn down your own house, it is very different with radios. It is illegal to sell and operate radios that have not been approved by the FCC, and that includes modifying existing radios. Unless of course his “modifications” to the Aruba access point doesn’t do anything , which is the most likely scenario, since any changes would need to include software update, and he doesn’t have source code access to the Aruba OS. 

Let us begin your rehabilitation Freddy. After you get rehabilitated, go back to your Sith lord Majidimehr on the ASR mothership and serve as the rehabilitated, repurposed, audiogon Trojan warrior.

But, watch this (all pinned timestamps, live blind tests, etc) and let your mind start polka dancing first. This is step 1 of your rehabilitation.

Interesting video.  He shows data of how performance degrades under load.  I had wondered that in the back of my mind since my Audio network switch has my computer, back channel router and Apple TV plugged into it.  The EE8 switch says to use one particular port for audio because it is isolated from the rest.  I’m thinking about moving the SW-8 from the Apple TV and putting it next to the EE8.  Plug everything into the SW-8 and then have one cable from the SW-8 go to the EE8 and on to my music server.  I’ll see if that makes a difference.  (I will also try just unplugging everything but the Audio from the EE8.)

I saw an improvement in the TV picture streaming when I put the SW-8 next to the Apple TV.  My assumption was that the long, 100’ ethernet cable run picks up some noise.  But maybe it is the multiple connections into the EE8 that are adding noise.
