What an absolute load of nonsense. Not one jot of evidence to support any of the claims. That's not a credible white paper, it's just marketing BS.

If there is jitter and phase noise getting through from the ethernet, why can't we measure it in any dac audio output?

Show me the jitter!

Show me the jitter that exists in the dac output without your switch then show me how it disappears when you put it in circuit.

If you can't do this simple task then your product does nothing. Prove to me its not a con.

Isn't that the same thing?

 

[SIY]

Isn't that the same thing?

Not necessarily. I was just sent a white paper from an engineering-driven loudspeaker manufacturer analyzing bass reflex design (they sell PR systems, which fall into that bucket). It was a rigorous and first-rate treatment, and I'm looking forward to its general release.

Scammers gonna scam. Honest and accomplished people are gonna innovate.

I've always thought of "white paper" as something seemingly too technical for plain ad copy while lacking enough real information to be called a paper, data sheet, application note, or any other term typically applied to actually useful documents.

 

[March Audio]

Isn't that the same thing?

Not quite. You do expect the presented information to be authoritive and have credible basis that's verifiable with referenceable data.

The things Swenson blathers on about in the document are eminently measurable if they manifested in the output of a dac. So why doesn't he just show the cause, effect and the improvement?

He doesn't because there is nothing to see.

In a good white paper, the content is there, but the tone is much more conversational, and it's pitched at intelligent non-specialists.

So on the "white paper" spectrum, it falls at the extreme of "ad copy with some techno-babble thrown in."

In a good white paper, the content is there, but the tone is much more conversational, and it's pitched at intelligent non-specialists.

That's the other end of the spectrum, "app note with all the useful details removed."

It does the classic of misleading the reader by presenting some technically correct (mostly) information thats credible in itself, but has no relevance / bearing on the actual outcome. In this case the actual output of the dac.

It doesn't matter what you put into the PC and how "clean" it is. As Amir has pointed out a PC is a hideously noisy environment. There simply is no relationship between the input and output in terms of the data itself or noise/jitter. This doesn't matter however because competently designed and low cost dacs just aren't affected.

Seems harsh... To me a white paper is more like a note targeting a non-technical, or at least not technical in the field, audience. I would consider all of my various "technical" threads here as white paper-like. More an overview and yes deeper technical details removed. A lot of white papers have enough detail for a technical person in the field to get a very good idea of the implementation (or whatever) without having the circuits themselves exposed. They are often to explain the concept behind an idea to a wider audience rather than be an app note or conference paper.

And yes they run the gamut from too technical for most lay readers to being just a marketing blurb with a few technical keywords (or just nonsense that sounds technical) thrown in.

Whatever - Don

p.s. I have not read the EtherRegen white paper, nor am I likely to...

"Yet even with published measurement evidence, those who don’t believe any of this stuff matters will then simply claim that what we are measuring can’t possibly be heard"

Alex, you have presented zero measurement evidence.

"Some will say you are all delusional, and that you are imagining what you hear. They are wrong"

So you will be able to present some actual evidence, and not just anecdote to support this view?

You are quite literally the weaver in the Emperors New Clothes.

Considering who wrote it, I assume it consists of the phrases "jitter," "leakage current," and "ground plane modulation" repeated in various permutations.

 

[SIY]

That's the other end of the spectrum, "app note with all the useful details removed."

No, an app note is usually about a single device type, with specs. A white paper is a broader thing than that, and a good white paper is full of useful details. It's just not written the same way a journal article would be.

 

[Blumlein 88]

Dude there's a ' white paper ' , we are low on ' white paper ' in the UK right now I will take what I can get .

You'll need to print the white paper for it to help with the shortage. Now if you print with the ethergen or whatever can you feel the smoothness in reduced jitter?

 

[Wes]

Show me the jitter!

Wasn't Tom Cruise in that movie?

I think you are confusing it with "the Color of Jitter". That flick that had Paul Newmann and Cruise in it.
