I have the 501-II, a Rosewood and a Kontra B, and drum roll, I like them all but lust for what the B gives me, but can't live with the lightweight midbass and bass, the B is tight tight tight, detailed, non-fatigued, --- but I have big Manely/VTL toobs and Maggies which accentuate the afore mention issues and hence make them worse. I have recently heard the Jubilee and it takes the cake. If you like the Shelter for the dynamics and ease, and Koetsu for the mids, then you gotta hear the Jubilee to hear what you missing in those two. It's not as lush as the Rosewood but-- not missing by much and brings so much more to the table. Mixes the Koestu and Shelter and breathes air and light into them, and doens't mess with what they do right.
