I have a 14K Brannen (with a 14K Williams headjoint) and just love the Brögger Mekanik™ mechanism on it. It has a real buttery feeling to it. This flute puts my soldered tone-hole, handmade Haynes to shame.
Add Maria to the list:
Marina Piccinini/Brannen/Cooper headjoint and LaFin headjoint
However, I'm going to assume that professional flutists have the means to buy any flute they want, so that they most likely would chose their "favorite" brand (unless they are being compensated to promote a certain brand. Should mention that Brannen does not have paid "artists" but rather donates money to scholarship funds instead).
I'm partial to Japanese flutes, not a fan of the Boston flutes
I've played and sold Muramatsu, Sankyo, Miyazawa, Altus, etc and repaired just about everything under the sun, and I haven'f found anything that can match the tonal power and variety and smoothness of mechansim than the Pearls.
A lot of emerging new artists are switching to Pro Pearls these days,
Erin Lesser (an NFA competition winner) switched to 18K Pearl
Zachary Kellogg switched to a Champagne gold plated cantabile. (NFA showcase this summer!)
Don't forget Daniela, She won this past year's Kobe competition!
Some people will not miss a single opportunity on this forum to remind us of what expensive flute they play! It gets a bit comical after a while.
And, once again, the spelling is Lafin -- not LaFin. He's not French.
Personally, I like flutes made by Arista and Hammig (especially the wood Hammigs). Most people would call these "professional" flutes although the original poster didn't list them (nor are Williams, Sheridan, Emanuel, and McKenna listed, just to name a few).
