I just got my beautiful A9930 which I won on eBay. What an amazing horn!!! The sound is so sweet and resonant, it plays so easy with Jody Jazz DV and Vandoren Java, especially the high notes.
The low notes are not as meaty as my Selmer SAII, because of the higher upper harmonics with silver body, but are very well articulated.
The best thing I like about Yani is intonation, it almost always is in green on my tuner, where Selmer needs a bit of adjusting.
The mechanics are the best I ever saw - no loose actions, no sloppy keys, just like Lexus. Well-thought and proper metal thickness everywhere.
I only wish they installed the non-sticky G# extra arm, just like Keilwerth does on their horns, but Keilwerth sterling silver does not have the same beautiful sound as Yani.
Also, some concerns regarding the lacquer, the horn is a bit more than a year old, but some wear spots start to show up. I think the lacquer they use is too soft which will wear off pretty fast. Anyone has the same issues?
When inserting the neck, it just stops there, where Selmer has a distinct metal to metal kind of sound, and I can feel when it stops, which I like better.
Otherwise, very nice horn!!!
