I have found nothing to compare with the Amperex 7062/E180CC pinch waists although they are expensive.
Budrew, if you hear the pop on first turnon with the amps open, I am surprised that you describe it as a pop. I have once done this a got a increasing frequency woop. All Denons I have heard, modified and unmodified, did make a soft pop at the start of the recording.
