Thanks, I've been reading a bit on phase shift or angle, same thing ?? Still trying to digest it, from one article it appears they're saying not to worry to much about it in an amp.
In one sense, you can consider the effects of phase angle being built into the frequency response (which represents voltage sensitivity over the full bandwidth): whether the phase angle is 0 degrees or 60 degrees, the voltage demanded from the amplifier remains the same. As a result you don’t have to worry that an amplifier is going to have to swing loads of extra voltage and current in order to cover the effects of a difficult phase angle.
Thank everyone for explaining. I read this as well which to me is showing what roberttdid is saying about the square wave. If the phase shift is distorting it would look like figure 3. In the link.
Bruno Putzey on phase shift in his purifi module.
The way I understand it if the phase shift is different between the two channels in a stereo amp then one signal would be slightly behind the other which would sound like distortion?
@atmasphere Is saying "to avoid this both channels have to have enough bandwidth that this is off the table."
Or I am still lost??
