Default Influence of the delay amplifiers for listening characteristics

I would like to ask what, who sees the link between delays and the impact of listening to the amplifier characteristics.

The decrease in gain of 3 dB is a phase shifted by 45, the sine of 0.707 of the maximum value, consider this very poor, for feedback and Vdif.

Thank

I see that the dependence between delay and the resulting sound amplifier is uninteresting.

No serious independent listening verifications, Federmann...

No audio amplifier should exhibit phase shift over the 20-20khz range unless the response is modified by for example tone controls which phase shift.

What has a 741 got to do with all this, configured with a gain of +10 and a low input impedance

Use a faster opamp and the problem will diminish.

Edit... the lack of speed of the 741 is why you are seeing the "differential" voltage between the inputs increase as frequency increases.

I, just used 741 as an example. For each amplifier, the same dependence.

Federmann, this is a real preamplifier, with input RC filter bypassed. Forget your examples of poor circuits.

Please show your good example, Vdif for the delay 2 , 4 and 10 .

Thank you very nice

I say again: do you have independent correlation between your statement and listening experiences ? Or what is your verification?

You have space here to say their knowledge and experience so please write.
