A message to respond some one
The English is not my advantage so the message must had a lot grammar mistook.
If I was you, I would not say anything how the specs effect the sound quality.
You can say how bad of the specs and the sound quality , but you should not hint the transparency = low distortion.
Did you say the tube devices sound not transparency? Or did you mean the phono sound not transparency ?
You know how to measure , you may know the electric technology, but you may don't know the audio technology.
I have very lot changes to measure the expensive hi-end devices of different brands, because a lot customers brought their units come to our listen room to have the compared with our products.
I have measured the wonderful units to study why their sound is tube like or transparency or sound digital .
Through a lot measured and studied I know how to make the sound like analogue but not digital .
Audio study is large different to electric study . I can not study the audio technology only in book but I must open and study by the hi-end units , a lot practice and listen are necessary.
Did you know the specs effect between OS and NOS ? The same unit, OS and NOS can had 15DB different on the THD.
It is a unit only with NOS design.
We have declared on the web page :THD today is extremely low with Sigma Delta chips; R2R ladders have good THD but nos as good as Delta Sigma .
In your point the most DS design must better than most R2R design.
In the web page we have declared the unit sound has Smooth, coherent and analogue sound quality and has no emphasise on any frequencies in audio spectrum, and more like real oil painting.
It obvious design for the analog or tube like sound .
It must some things like the pure analog design .
There are over 3000 users and I had got a lot feedback from users says sound wonderful, I don't think these users don't know how to listen music .
A few Americians may dislike the Chinese products, like Mr. Donald don't like Huawei .
But music has not limit of countries. We are not only enjoy the Chinese music but we also respect the oversea musicians .
The most people just want to enjoy the music but not enjoy the specs.
