Technical and scientific discussion of amps, cables and other topics.

Re: This I do not understand....

Your example of 3K, 15 degrees..

1/3k is .33 milliseconds per cycle, 330 microsec's.

15 degrees is 15/360, or .041 of 330, 13 uSec...good example...

For a stereo amp to reproduce that with R-L coherency..yes, it doesn't need 100 Khz capabilities..in fact, 3 Khz would do, as long as the channels match..

But, for an amp to faithfully follow a complex audio signal without introducing transient delays at that speed? Hmmm..each channel has to faithfully reproduce the audio signal, without affecting the time relationships between, regardless of the signal content..I do not know how to design an amp that is low bw. but still faithfully passes 10 uSec transients..

To answer your question...some believe it is necessary to have high bandwidth in order to maintain the time relationship between the lower frequency information and the higher freq stuff. I think I belong to that group. :-)

I am absolutely confident that I have not answered your question to your satisfaction...I'll think about it...Sorry...

Cheers, John
