Dave, even in the highest echelon you can hear clear differences between amps. With some of the amplifiers that have ultra high resolution you do not only hear the beginning and decay of tones but it's as if there is "air" or texture surrounding the notes even prior to the beginning of the sound. Take a guitar player. With a high resolution amplifier you can hear all the notes and decay of tones but with the ultra high resolution amp you hear tiny movements of the air molecules (probably caused by the movement of the guitar player's arm or change in his body position). This is what I actually mean by ultra high resolution, not the hyperdetailed scratchy treble that is the hype today. If you hear this phenomenon once you will never forget the sound. Many high end manufacturers are not able to achieve this sound quality even when they have the financial resources to make it happen. I know you'll probably condemn me because of serious bluntness and narrow-mindedness but I'm only trying to describe some phenomena I've encountered during listening sessions.
