Archimago measures Ethernet cables

...and a floater.

 

When I liked that post I hadn't even read the Archimago article. :)

I had virtually no context and if you read back I've stated nothing about the Archimago test.

If you think I'm wrong them please show me.

I don't log the audio output as my ears are more resolute than the test equipment I have and the time I can afford.

 

Haha, you keep trying to put me down and you come out with these kind of beauties.

I'd sincerely welcome your getting involved.

 

You've been on my ignore list before for quite some time actually and I think you'd be only one of two.

It's hard for me to get too involved with a conversation with you when I instinctively scroll past the majority of your posts.

Just another one of your constant superficial and unnecessary putdowns.  You may learn something useful if you read the posts.

Entirely a reaction, it was coming.

Go and read back how many times he's been baiting me for liking a ******* post.

You are right, but when you lose someone you lose them.

Hey Ric / Ken, when  you're ready for a chat about another testing paper, let me know your thoughts on this: https://www.researchgate.net/publication/242508896_Detection_threshold_for_distortions_due_to_jitter_on_digital_audio 

 

I haven't seen this referenced anywhere before in this thread, but it seems to indicate that trained listeners can find it hard to detect jitter at <250 nsec. This is a real world ABX with trained & untrained listeners, with trained listeners outperforming untrained (576 nsec vs 250 nsec thresholds).

 

Not all "amounts" of jitter are created equal.....   what will appear in the analogue output is strongly dependant on the spectrum of the jitter ....  and whether that is audible depends a lot on what "tells" end up in the output  (distortion is often inaudible, until we get something which magnifies its audibility .... like if its cyclic, etc.)

Edit: I also agree with whoever said it, you do come across quite rude sometimes too.

I find this quite mind bogling.

"rmpfyf" to me would have to be the most informative, most patient and mannered poster in this whole thread!!

He puts ideas out there for us to think about and gives us some of his alternative viewpoints.

As a few of you seem to take a particluar pleasure in aggressively targeting my posts on basis of their authorship and not their content, I'll take indefinite time out from SNA. I'll leave the PM on for a week if anyone wants to keep in touch outside.

Really unfortunate that it goes this way. Another good guy leaving SNA

I really enjoyed reading your posts and have picked up some great insights along the way and you always made me think a bit more.

Nah, Bob is right.... sometimes he does come across rude and unhelpful.... but it's all part of the charm, and doesn't bother me any more than a bunch of other trivial things which I get over.

I have contact with Ric outside SNA.... so I blew him a kiss.

But to be fair, sometimes when one writes a reply, they don't see how it can come across. Often it's just a case of being too focused on the content of their post, and not on the delivery. And i know I have been quite rude myself, on the odd occasion, but only when provoked by personal attacks. Hope I didn't muse too long on which "adjective/adverb combinations" on this post... LOL

Well, too focused is right.  He had gone way too far down a rabbit hole and  I really don't think he could see it.     I would have rathered he stayed around though.

Nothing to see in the OP.   All predictable as per measurements, Ethernet is bulletproof and bit perfect if you work within the physical and soft  limits of TPC/IP protocol, when you transmit 10-15GB to a device and it produces exactly what’s on screen is there an issue with Ethernet?  No!  You’ll know when there’s  a problem ?. And this place that does this uses Cat4 and some unshielded Cat5e with standard $10 switches!     If this can handle this amount of data in  minutes it’s going to do any resource intensive audio regardless of sampling rate and data thrown at it!   Most Audio apps and streaming devices will have RAM buffers built in to deal with interrupted transmission so you get uninterrupted playback, I’ll be surprise if they didn’t and if they don’t, don’t use them,  it’s that simple.   To claim noise such as intrinsic etc, note that the measured is at the output of a DAC,  to say that the AP555 isn’t revolving enough due to the widening of the base of the Fundamental and that jitter it’s not detected due to the widening!  Well the measurements are taken from the output of a DAC with semiconductors  and RCL components on the output, all these components produces “noise”. that will show up that masks any claimed  “additional noise causing jitter in the digital transmission  “ that’s “not high enough resolving”  AP555!   Well the AP555 shows -140 -180db, way beyond the claimed -115 db thread hold of hearing!  
I’ve tried to understand the claims that were made but it were never specific until this thread,  I’ve also instructed that poster to challenge his claims  on ASR because he claims Amir has no idea what he’s on about when it comes to “jitter” on other posts here on SNA.  Now  I understand what the belief was .  Valid points If you’re designing high speed transmission oscillators, however you can’t just continue to improve the quality and spec of components at this level as Mother Nature and physics comes into play, so you need to designed around it to achieve your designed criteria’s.

it’s not the 1st time this poster has done this,  we have cross paths in multiple topics, in one of the topics he’s gone in to challenge all things to be weary of that I’ve presented,  as per observed; gone down too far In one rabbit hole, then all of a sudden all his posts are deleted!  Check the EV thread as one example, that’s one and there are many more, hence the reason I don’t reply.
