I'm a masters in clarinet, learned on a RC. This instrument is shockingly well tuned and the sound is even throughout the instrument. It's more centered than previous RC line instruments, the Legende reminds me of the sound of german bore clarinets. The keywork is definately more comfortable than previous Buffet models.
The only complaint I have are some of the mechanical aspects of the instrument. I need to take it to the technician every 3rd month to eliminate rattles and I think there could be more robust ways of aproaching the construction of the instrument to make it need less maintainance.
