I have a brand new 984 Sovereign (very kindly sent over to me by Besson) to use in the World Premier of Stockhausen's Mittwoch aus Licht in the UK.
It is superb.
I agree with JIm, it has a brilliant high register which is very clear and focused and It also packs a punch in the low register.
Intonation is bang on and the valves are great (although tricky for me at first, I wanted to use CC fingerings)
The Music Director at the Stockhausen Foundation in Germany commented how much she liked the tuba and she is used to the F tuba sound. She thought it was perfect for this opera.
If anyone wants any info or advice please PM me.
There is also a silver 984 at Phil Parkers shop in London for people to try....
