Are future improvements in Amp/PreAmps slowing to a crawl?

My point was that unless you attach a distortion-less analog stage to the back end, the full resolution cannot be realized.

I can run a 16 bit dac that will out perform a 24 bit dac simply be using a distortion free (0%) analog stage.

In a DAC the analog stage is the weak link.

I'm assuming that you have used tube output stages and recognized the difference in sound quality.

^^The premise of the post above is false.

Try running an analog source through that output stage and you will see why.

As a bit of a tip: its probably not a good idea to talk about 'distortion-less' in the way that you do, it strains credulity.

hi @ roger_paul
I guess the loss of distortion has become a single minded pursuit for many amp maker - HAlcro; Neodio; LAvardin - do they not address 'velocity' already?
It is fascinating that single ended amps and valves - particularly OTL designs have such legions of fans and they major on the reproduction of a live sound.

Yes, straining credulity is my job. I hate it when people touch my stuff.

This is a good question and the answer is no.

The reason is because you need a method of detecting velocity first before you can correct it - and then you have to do it in real time (without any delay). 

If years ago Ray Dolby was to post a comment the he has found a way to reduce noise in tape recorders - the reaction from this crowd would be "that's impossible - there's no way to prevent the magnetic material from....bla bla bla."

Sorry.

Honestly you know from my previous posts that I do not consider myself as a "know it all" but I do have much more data on the problems with analog amplifiers and ways to make them work without distorting.
Is it difficult to do? Hell yes. Is it impossible? Hell no - I got it to work.

I have tried to share with this audiophile community some of my discoveries regarding sound reproduction that has resolution on a biblical scale. As it turns out I do have a distortion-free amplifying method already and it does produce "live" sound by default. This was the target of my work. It's not magic and I'm no genius. I simply took the time to figure it out. I have had to learn how the brain recognizes a live event from a reproduced event. The accuracy need to satisfy the brain that it is real (live) is a specific property of the sound waves you are listening to. It turns out to be a very simple yet very difficult thing to get right. As I've said until I'm blue in the face - its velocity. The actual speed at which the music signal traverses through an amplifier. It has to match the speed of a sound wave traveling on the outside of the amplifier. The solution is to synchronize the output velocity to the input velocity. It comes in at the speed of sound and it exits at the speed of sound. (same thing as air).

That is exactly what I have done. Period.

When you do that - you have cloaked the electronics and emulated the the most important property of air - its stable velocity. Your brain is satisfied that "this is real and happening now".

The bottom line is going to be the near future. That is when the full method of distortion free sound reproduction will be shown. While it is compatible with current recordings, I am about ready to start making recordings that also have no distortion so as to realize the complete capture and playback with unprecedented results.
I can clone a sound event and repeat it on demand. If the clone is 100% correct - you will not be able to tell the difference. I am not afraid to do the homework even if it took years.

All I can say is watch the news.
