I asked Chuck some questions about his new tuba a few months ago, and this was his response.  Take look at the Canadian Brass website to see some pictures of this instrument.

Hi Daryl
Thanks for your email
I guess I have had a pretty steady flow of instruments go through my hands. 
I don't presently have any instruments I am not using in some way.
The Yamaha is a 623X, meaning not being produced at this minute. It was 
designed at the same time as the 822F and shares many parts. I consider it 
to be the finest instrument I have ever had. Yamaha is considering its fate, 
trying to determine what kind of consumer interest there will be in carbon 
bells, etc. 
As a point of interest, I think the Yamaha 882CC is a great instrument well 
worth a test on your part. It is a fine all around instrument, a bit larger 
than the one I use.
Good luck
Chuck
