I suggest that you consider the current Avalon top-of-the-line, the Sentinel. If Neil Patel decided to replace the Osiris with the Sentinel it's all for good reasons. I trust his ears and believe in the forward progression in technology that creates better components. I would also suggest that you work closely with a dealer who knows the product and will be there to support you regarding placement, component matching, etc.
Good listening!
