So you don’t understand THD either. Much studying needed before you can talk sensibly.
Surely to God people aren't that stupid to think everything sounds the same? If people can't hear differnces I suggest they find a new hobby.
I prefer to buy hardware that allows me to come the closest to the originally recorded input as possible.

Sorry, no can do because he isn't wrong. You can't correct someone who is correct.snip
I hope someone from the objectivists side will correct you on this, however I fear there's too much loyalty here. It certainly looks like it.

Aha! A measurements purist, I see.
Obviously, most of us do not want actually recreate what you would hear live - standing next to the photographer at a recording session like the one below. Nor do we want to hear the tracks as recorded.
Rather I want my stereo system to accurately reproduce the final product that the mixing/mastering engineers created by manipulating the "originally recorded input." That final mix/master is what gets sold to buyers of recorded music, although the mastering engineer is likely the one who takes the final mixdown and decides on those dreaded compression levels that can reduce dynamic range and squeeze the life out of some recordings. Those stages are where the actual "creation" of what we loosely call a "recording," and can take place many years after the actual recording sessions if the raw tracks are available for re-mixing and mastering.
I am also aware that some music lovers who are audiophiles have their favorite mixing/mastering engineers, just like film buffs have their favorite directors.
(I'm not an expert on this, so if any of our resident engineers would like to correct or embellish my ramblings, please do so - and my learning about where my "recordings" come from will continue.)

... filterless NOS DAC is not [fine], unless you upsample the 44.1 content 4 or 8 times (properly) and then reproduce it with a NOS filterless DAC.
Prove that signal (below 20kHz) amplitude has stabilized due to applying a LPF above 22 kHz or so (aside of anti-sinc roll-off correction which obviously intentionally corrects the upper end, and aside of LPF's added roll off).
In other words, prove the existence of varying signal amplitude because of reconstruction waveform.
You can't write crazy things.
Yep. I upsample 44.1 content 16x in HQPlayer or XXHighEnd before sending to my NOS filterless DAC.
The potential trouble with upsampling is that it is a processing, hence it can induce the error as well, change the sound on its own. So it's not only about benefits. Besides, DACs internal architecture must support filtering at a higher frequency threshold to allow its benefits.
Oh darn ... the 20kHz varies in amplitude, about 6dB no less so this is 3dB drop-off 'averaged' over time.
And then there's the part where those three are often combined in some fashion.The question that follows is what one considers an output stage.
Is it the output buffer circuit ?
Is it an I/V converter ?
Is it a post filter ?
Been reading this thread and since you seem to be an expert on ADC/DAC and I am definitely not would you say that it would be recommended to have a NOS R2R DAC in NOS mode feeding such DAC with pre processed DSD (or PCM) content on external application (aka HQP)? I am changing the input "digital" form with pre processsing and would like to confirm if I'm doing the right thingNote that those that prefer filterless NOS R2R DACs purposely change the intended waveform thinking they are doing the right thing.
since you seem to be an expert on ADC/DAC
That proof has already been delivered with 10kHz and 16kHz plots which are both below 20kHz.
You just don't believe it.
Oh darn ... the 20kHz varies in amplitude, about 6dB no less so this is 3dB drop-off 'averaged' over time.
People like Zalive don't even care about it.. they listen and when they like it simply claim it is better.
Nothing wrong with that except that when something SOUNDS better to them it doesn't mean it is 'technically better'.
Using dithering, I'm followingYou can 'safely' use a filterless R2R DAC when you are using HQP while set to up-sample (using its excellent filters) to at least 176/192 or even higher if the DAC supports it. This will move the crap all the way up where speakers/headphones and ears don't even do anything any more.
It should have a relatively clean area between 24kHz and 100kHz.
Agreed and that is what most people doesn't know, I didn't some time ago but I suspected it was still filteredWhen someone likes the sound of a NOS filterless R2R DAC that's fine too, they just should not claim it is technically a better solution because it lacks the (always sound degrading ?) filter
When an R2R DAC device also accepts DSD it probably has a different DAC 'section' for it. I don't think you can toggle the ladder bits that fast...
R2R DACs are for converting PCM and are usually pretty limited in max. switching frequency so to reproduce DSD one would have to convert to PCM first.
IME you need also the right modulators go see HQP 4.11 for the EC (extended compensation mods) filters IMO are negligible at least on my system.In DA conversion you just need to use the right filters. Some of the 'special' filters usually can produce nice square-waves and needle pulses but these are only test signals for tech guys... they do not exist in music nor in any recording nor is it an advantage of a DAC design if it can do th
