Yes, seamless integration across the audio spectrum. The character of the ribbons or ATM is completely different from a dynamic woofer. One of the reasons big Maggie’s are attractive (with massive power amps). You get the same character of sound across the audio spectrum. I never could hear the difference in character of the drivers on my ESS AMT 1D’s, until I could. Then I happily moved on.. and up… typically most of us increase our investment over time… and each level up has less overall weaknesses and more strengths (provided you choose wisely).
So many aspects of audio are unimportant until you hear them… then you just cannot un-hear them.
