Accuphase A 50v a good amp?

 Just curious if anyone out there has/has had an  Accuphase A 50v class A amp in their system and if so, what it is like.  I currently have a Luxman class A amp and love it; I am thinking of picking up a carefully used a 50v to biamp.  I plan to use the Luxman for the highs (since it has attenuated input I can adjust the level of the highs) and the a 50v for the bottom end.  Of course, it could be that the Luxman become redundant but I doubt it since the Luxman is in such good shape..   Can anyone tell me any issues etc....  sonically I think I know what I am in store for I am open to any advice.
