Our IC thin film is 40nm thick and is used in all our precision amplifiers. You can read the datasheet yourself (AD8229) internal 3k resistors against 6 Ohms external for a gain of 1000 and +-1ppm non-linearity for a full 20V p-p output. No noise issues of any note either.
Marce, Marce, Marce,
When it is failed open of course! Could you please be more specific in your questions?
Again another issue of difference, just how good a PC designer can you be when you need to use more than a single layer?
More layers, more contiguous return paths, more power pairs=more distributed planar capacitance=lower impedance power delivery at the frequencies you care about=less EMC=better signal integrity
ER not really, roughness of PCB material can be a problem with very high speed signals because of the impedance mismatches it causes, audio you don't even have to worry about skin effect and all the rest... or normal digital.
So for audio the effect is about as close to 0 as you can get.....
IN digital it is ridiculous... How can a resistor used in a digital circuit impart a sonic signature on the resultant analogue waveform after conversion.....
Audio is a mixture of analogue and now digital electronics, it is no different from any other field of electronics, this is true believer fantasy, sorry.
Its like the Bits aint Bits mantra that so many spout, they are, bits are just that bits representations of binary data, analogue signals again are just analogue signal be they carrying image, sound or any other information... The rules and problems are the same for any field of electronics.

Instead of feeding the believers, you have a vast depth of knowledge, why not give a considered factual answer instead of a inane blessing on the faithful.....
Yes, Marce, I have a vast depth of knowledge about audio design. You, however, do not.
My associate, who has been my layout guy for the last 30 years, could teach you a thing or two, but he doesn't bother to contribute here.
Thinking, just because you are a layout guy at some company, that you can tell the rest of us what works and what doesn't in audio, is not really very helpful. You lack experience.

I know it John, I can see that diyAudio no different from other forums I participated in.
There is the same strictly separate types / groups who are trying to fight each other in this question about the sound signature not only due to the schematic / electric design.
But also affected by the choice of the components selected to ralicerer the design / schematic.
I could content myself with this realization and use my experience to choose the components with the best sound signature, components that will give the totality optimal sound.
But I am also technician, and these problems/lack of explanations has plagued me for years.
Problems I have not experienced in my professional work as a technician, here follows everything the textbooks, because I do not work with audio engineering.
Audio is only a hobby for me.

nice John
Comes from real world experience. I spent the last 12 years before I retired setting up and mixing systems for live sound reinforcement, and/or live recording. The live recording was atypical - my clients were mostly the organizers of academic music festivals. The partcipants wanted recordings that duplicated what the judges heard as well as is possible. All that I did was do the best job I knew how of satisfying my paying customers. Seems simple enough, no?
That appears to be an assertion without evidence or proof. If there is evidence or proof, where is it?
That is a very vague statement. How many feet or meters is "quite a distance"? Is it the same in every performance space? It seems like you think that it is something to be avoided? How can it be avoided if you can't tell me what it is in a meaningful way?
Many of those things can't be packaged in the form of a CD or digital download, which are the most common deliverables.
What reference? I see no stable, reliable reference. I see some references to motherhood and apple pie. You want me to build a product or science based on that? ;-)
At this point the list of pontifications have long since degenerated into a cacophony of platitudes and speculations. Now we have a denial of accepted professional practice.
LEDE is generally a studio technology. In general studios depend on solo or very small group performances, multitrack mixdowns, and synthetic recordings. This is your reference for sound quality?
Pluuueeeaaase! ;-)
Its not the language skills that are the biggest problem with the above list of pontifications and speculations. The big problem is that it appears to just be a list of pontifications and speculations, with no apparent detailed facts or relevant experiments or science to support them.

The above is the conclusion that most people reach if they gather and study the existing supporting evidence or get some personal experience with the issues of their own.
Of course, because 20Hz-20Khz in a domestic environment is so much more stringent than something that has to work in a fighter jet, or a power station or a submarine. Stands to reason the human ear is orders of magnitude more sensitive and needs a particular genius to lay it out properly.
I am not quite sure whether you joker here, or you just do not know how sterio works.
Headphones are the ideal, that is what you should aim to get as much direct sound in the ears as possible.
Is this sound correctly so doing brain the rest, it can not do otherwise, the brain will form a sound image around the source point from the sound.
Therefore LEAD absolutely not a stupid thing
You can hear it in practice with B&O new BeoLab 90, which does the same as LEDE with DSP.

Obvioiusly, you are cornered, and you have turned from baseless speculation to personal attacks.
Many will disagree with that, but it really doesn't matter. You can do good listening tests with headphones, pretty much just a matter of hooking them up.
I never said it was stupid, I just said it was more relevant to studios than live venues.
But again it really doesn't matter. You can do good listening tests with a LEDE listening room.
The idea that you can massage an arbitrary listening room into an ideal listening environment with a DSP gas been debunked many times.
