Right; the issue being if it is so hard to tell what equipment sounds better that we must use DBT studies and very intricate measuring devices to enable us to hear minute differences in the sound of audio gear and there-by make a distinction regarding which equipment sounds better than the rest of the equipment...then how come musicians can enter a crowded room full of equipment and within a few minutes be in total agreement about which units have the best sound. This is without using any of that rigamarole suggested by audio reviewers. Does that make any sense? LC had the idea; the rest seem confused. Thats my question; how do they know if it is so hard to define this? I make no judgement; just curious about this little subject.
