Relationship between Ethernet Switch and SQ

How m

How many times do we have to relive this?

@fredrik222 ....meh...

...um, also...

A device used in casual conversations to separate two different but related things.

Channels from the SFP to the CPU are direct but it doesn’t mean you’re not going to get interference from other circuitry...um, also...ground plane on the backside aids in isolation, would just be another way of saying it and not that the channels are the ground. Humbug indeed.

Maybe double up on the meds?

That, and you’re a fine one to call out anyone for personal attacks.

first you agree he says ground runs to SFP to the CPU, then you disagree. Either way, any one can watch video where he clearly says the ground runs from SFP to CPU, which it does not. 

I think I get it now....you're on meds, right?

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.

The mods are in the linear power supply...just to make that clear. I never said they were in the Aruba and neither did Chris. He mods the power supply unit for the  Aruba, as far as I know. 

he literally says the ground is on the backplane, 

That's exactly what I said. Why the need to correct me on that?

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.

How you get that from what he said and did explains a lot. Your implications are faulty and intentionally misleading. He's clearly talking about the path from the SFPs to the chip and not the ground. A wave of his hand while mentioning the ground on the backplane and then pointing out the clear paths of the signal doesn't mean he's saying they're related. He talks quickly but I have no problem following what he's saying. 

Anyone who's on the fence about this needs only to go back and watch the video and it will be clear what he's talking about.

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.

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.

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.

Here's one of Chris's videos on the Switch X:

@fredrik222  It would be a lot easier if you just called both of them and discussed it and got back to us with your findings. You've shown yourself not to be an honest broker so relying on you to educate us is a non starter.

Or better yet, let them know of this thread and how you feel about them. Maybe Bill or Chris could come on and speak their mind a bit? Others who've had been disparaged have and it helped to clear the air some. 

All the best,

@nonoise  so, the moderators did not like calling the guy what he is. 

I have no idea as I never read your insult (which is all you really do).

for instance, he says all electronics are contained in the SFP, which is patently false. Open ANY switch and you will see this very clearly. 

Isn't it clear that he's referring to the electronics inside the SFP that allow it to mate to the electronics in the switch? He knows there's electronics in the switch as he talks about electronics in the switch for practically the whole video. Were you drunk when you watched it?

As for everything else, I guess you didn't bother to call either of them and discuss the matter, from what you wrote.

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,
