The performance of the top end Jupiter doesn‘t come as a surprise to me. They can be close to more expansive horns. Their Top series seems undervalued. What really surprised me is the YAS62. You state it is yours for a long time and you played it a lot. Based on the clip alone I would have said it is the one you are least familiar with. It spoke hesitantly, was less loud and it sometimes seemed you had to struggle. I would have guessed that it may have slight leaks. My preference would be the SAII.
