They're just different...
Both are wonderful, yet the Klipschorn can't do what the Jubilee can do and the Jubilee can not do what the Klipschorn can do.
Surely the both can play the same frequencies to a point (Klipschorn can't dig nearly as low) and the Jubilee has trouble sparkling on top.
The Jubilee is much more effortless and has a tremendous sense of scale in terms of imaging that a Klipschorn can not match, but the Klipschorn is much more effortless in terms of ease of operation... when it comes to the Professional Jubilee.
Is the Jubilee better, yes... is it more trouble, yes. (A lot of this is due to the steep learning curve necessary when using the Pro/xilica set up).
I never liked the sound of a 'Cheeky' horn... but that's a person preference.
