Thank you. That was my gut instinct on both reading about Zellaton and what the multiple recordings seemed to produce.Three or four years ago in Munich, I heard the Zellaton Reference Speakers powered by YS electronics. The problem is that all the equipment was unknown to me. I had no baseline to separate the sound of YS from Zellaton. Overall, the sound was mesmerizing, with a clear YS/Zellaton synergy.
After getting a grasp on the amazing transparency of the Zellaton speakers, I can tell you that they let the character of the upstream electronics shine through. It's easy to hear the subtle, and not so subtle, differences in any electronics that I've had in my system with the Zellatons. So, in retrospect I can only characterize the YS sound with very broad-brush strokes. They are extraordinarily musical, with a very refined natural sound, and clearly produce very realistic imaging. And you are right, they are very, very expensive. Gideon Schwartz is a fan of YS and can offer a much greater insight.
I did ask earlier on one of the Zellaton threads about whether they expect to make your Statement into an Ultra version as well. Do you know? I am sure you just have asked! Would love to hear the Statements some day.
