Dx Super A - a module to be coupled to Dx amplifiers

[lineup]

I have looked through this topic.
But at no point I can see anyone question this idea.
And noone have tried to figure out what is done to the audio signal.

Of course this circuit will effect the clean signal
and add distortion.
It would be nice to see what distortion is produced.
If a difference can be audible there is probably distortion of high magnitude.

It can be easy to make a SPICE simulation to observe the effect.

My own prediction is there will be considerable increase of THD.
And this is something that we normally try to avoid.
Therefor I can not recommend such a circuit in the signal trace.
It will destroy signal quality.

There's a new thread, updated, about the subject.

Go to the new thread.... it was generated after this one and it is a consequence of this one.

Also i suggest folks to refer to the Dx Supply that was posted in this same thread... search for march, 28 layout posted.

This is the good way to know what is going on as this thread was almost abandoned when the other was created.
