I don't think so John, I really don't I don't limit myself to esoteric audio design and actually have studies and study all aspects of PCB design and have done it for many many years (over 30 in fact).
I don't tell you or others what works and what doesn't in audio, but I do question some of the BS myths and ideas you promote.
Nice to see you have used your second type of reply the pull down, I remember one from ages ago where you called a lot of us amateurs... Yes I am just a layout guy at some company, funnily I can back my experience up with some pretty fancy projects such as being the main layout guy for this little lot:

As well as being CID registered with the IPC.
So I don't lack any experience in PCB design, but hey pull me down, even when you don't have a clue to my abilities, it will help you in your support of such REAL components as Bybee's.....😀😀
We all bring our own little bit on knowledge to the forum, and all our views are valid if not always correct....

nice John
I and also others understand what you understand about audio, I and also others understand things about audio that you might not.

I am still waiting for some technical reason how a resistor used in the digital section of an audio replay chain can impart its own sound signature on the sound....
Now instead of direct insults (not from you, directly) from the believer section why don't you try and answer my question and give me some possible mechanism or path to do some research on....
No it's not an insult, when you are in the firstt place almost tells me that I'm an idiot because I use LEDE.
Ps Ps My respect for professional audio is not great after having spent about 1 million Danish crowns over the years, that's why I switched to DIY . And then have obtained better sound than I ever had before.
However, I'll take my hat of reverence for Beolab 90 and the B&O's technician,
Unfortunately is Beolab 90 outside my reach financially.

Anyway when I get back home, I was looking through my laptop and found a couple of papers on measuring resistor current noise that may be of interest to you Max... They seem to go into some interesting detail....
I think Marce said this:
"We all bring our own little bit on knowledge to the forum, and all our views are valid if not always correct..."
I disagree that all views are valid, given that two people can view the same scene while only one is knowledgeable about which seen things are illusions, and which are real objects.
Viewing a scene may seem trivial, but I know of places on the great lakes where the above is very true - the difference being knowledge of the difference in appearance of mirages versus real water and land, and knowledge of the actual geography.
On land there are similar pitfalls for the naive observer.
The same applies to audio. There are heard things that are illusions and others that are reliably heard things.
No big Vics here, its been worn away🙂 and more to come, well go is more appropriate....
That is a figment of your imagination. I don't think such things, and I never said that. I said, LEDE has its place - studios, but the real world is composed of more than studios.
Giving you the benefit of the obvious doubt: Maybe Thor2 you should stay off what are for you foreign language forums until you learn English well enough so you can understand it well enough to not make trouble for yourself.
Well, considering a situation that we hope cannot exist in modern times with reasonable gear:
If the resistor is horribly noisy or distorting...
If the digital link has no effective error detection (and hopefully correction) ...
If the sound signature is that good sounds are generally turned into obvious trash... Subtle changes are very unlikely.
Many do not realize that error detecting and (hopefully) correcting links are the modern norm.
They do not understand that an error-free digital link adds no, that is zero distortion or noise to the signal.
They do not understand that characteristic sounds or colorations are always the results of some kind of added distortion or noise.
The modern audiophile press contradicts any or all of the above at will...
Yes.
Some you are dealing with here are not naive observers and also have reliable hearing.
Dan.
The second claim is false - Reliable hearing does not exist in humans - all known humans who have been tested are subject to various illusions and biases related to hearing.
That error puts a clear limitation on the potential reliability of the first claim.
Many here seem to doubt even older science when it comes to listening tests. DBTs were first published and had their need established no later than 1950, but many still deny and resist.
Try taking it at face value.
Please notice that I didn't say that people who believe otherwise are idiots.
Do try to not become emotional and see all sorts of things that are not there.
Remember that I have professional experience in both studio recording and live sound and recording. I see them both as being important.
I suspect the thinner the film the better the performance as long as you don't run into thermal issues.
Which would you rather use today a discrete instrumentation amplifier or an IC version if the noise, gain and bandwidth are the same?
This thread is heading rapidly towards closure given the content of the posts I've just deleted.
Stick to the interesting technical aspects, cut the personal insults, and the thread just might live to see tomorrow...
For long term matching/reliability IC anyday, my NOS AD624's from 1982 work to spec right out of the bin.
BTW no evidence/published basis on your first statement.
EDIT - Heed Mooly guys I can only guess that the density of arny posts means trouble.

AD8229: $200 in small qtys. Precision does still cost. Glad we don't need that level for audio!
There's a cheap version under a new number I forgot. That one's for the oil search guys, downhole 200C.
