OK, here's the report.
The Azumi tone holes are somewhere in between Altus and Jupiter..
Jupiter tone holes are filed but not flat at all. There are no course file marks on the Azumi or the Jupiter anymore. The finish could be a little better but it's passable. The azumi is not as heavily flattened so the tone hole isn't completely level (and the rims not too wide.) There's room to work to get them flatter and thinned if necessary. They can be worked on.
The Altus are really wide rimmed, (like Miyazawa's) The finish is beautiful but very wide and they are FLAT. But the rim is way too wide. They can be thinned to a degree.
The soldered tone hole models on the Altus are much better..(if you want to spend $8k more)
Keywork on the Azumi is nice and tight and not flimsy. The quality of the casting is comensurate with the price. (i.e. from looking at the underside of the G# lever.) Ribbing is very stout.
The Z-cut headjoint is very square with modest undercutting and overcutting. Taper appears to be very traditional. (in other words the taper is not extreme to accomplish the same thing and introducing other problems for students later..) Loud, freeblowing, and responsive, just what everyone wants these days. Blow anywhere near the head and it sounds great...
If you are an old school player who like smaller holes and lots of tone color, you might not like the cut. But it is what's popular out there today and will give a student immediate gratification tonally..
Scale is the Altus Bennett scale. No problem there at all..
2 models available. Silver head, plated body, and all silver tube. Silver meaning britannia silver .958. Altus claims the silver content for it sounding darker, but I don't find them to be all that dark with that headjoint. Nice feedback to the player with some depth, but tonally it has more sparkle than darkness. Overall I do like the sound compared to other things in the price range.
