Influence of the delay amplifiers for listening characteristics - Page 6

We have real results, Federmann...and you ? Only theoretical blables and claims without listening verifications...

Listening tests are already going. Confirmed the delay is shorter = better sound. Border delays the onset of distortion is heard is to be found. I say 158ns to 100 watts.

Used (compared) amplifiers in test? Other equpment (signal source, used speakers)?Or, as usual, again only simulation?

Maybe simulated listening tests (in MC11, 3D version).

I'm interested in the views and experience of others.

There can read that 1/10 signal, the power output is 1/100 of 1%. We can talk about the distortion of 1%.

I'd like to return to the topic.

The first measurement, so far without great comments.

Influence of the delay amplifiers for listening characteristics

Example of measurement delays.

Topic has become disorganized. Soon I will add mathematical relation between delays, slew rate, bandwidth and voltage. All complemented by measuring the real amplifier.

Good night.

Overall feedback vs. local feedback and reserve gain

We can real measuring results and correlation with real listening, Federmann....where they are, do you have them ? We are not interested for your prehistory circuits from the year 65' or so...
