The audio world continues to surprise me. Big time.

You'll recall the fellow who, despite being quite intelligent, just could not get the concept of how S/N of a 16 bit system was calculated... Something John said before was very apropos, though perhaps not in the way he meant it- there are people who are mired in the past and cannot grasp newer and better ways of approaching problems.
Yes, given that I do tube designs, the cognitive dissonance meter ought to be pegged.
The measurements are filler. You can see similar in any publication. The tracks are were the fun is, especially the music tracks.
Read the original file into a DAW, in 32 bit workspace. Then attenuated by 2^12, converted to 16 bit without dither, converted back to 32 bit space,
and amplified by 2^12, and then back to 16 bit. So only the 4 upper bits carry any content.
No need to be so touchy, John. Nothing is perfect, including digital. But dither works. Did you listen?
And you, did you listen?
For those interested, here are the links to the drum tracks I mentioned:

An externally hosted image should be here but it was not working when we last tested it.

Werner, thanks for that - quite educative. Clearly it does work. But what would you compare 16/44.1 (dithered) to in undithered resolution terms? A sonic answer, or a mathematical answer would both be interesting.
This thread has been continually poisoned with gratuitous unpleasantness aimed at John. Mostly from those with very little to say of any worth, so far as design of Analogue line stages is concerned (keeping the thread title in mind). Rather than being touchy, he has given us (those that are receptive) a good deal to weigh and consider, in approaching design of linear equipment - THANK YOU, John
I second that. My own phonostage is Vendetta-inspired, and inspiring ...
Thanks guys, for a little support, it is appreciated. The fact is that this thread was founded on the Blowtorch preamp and I have tried to extend it to discussing subtle audio electronic design issues that people bring forth, including my own experience.
However, we are still considered 'kooks' or some-such. I would prefer to leave those who don't believe differences are possible or at least significant to their own preferences.
By the way, Jack Bybee still lives! I talk to him several times a week, and he is now mostly involved in a new IC based module that actively reduces DC noise inside of equipment. More soon.

How cool is that?
Werner, thank you for the samples, interesting. This last link does not work. Can you please post another link to this file?
