ericsch,
I have 505 UX. If I had to describe the sound, as futile as that may be, I would say it is not noticeable. Of course, it does make sounds. It may be what people would call "neutral". Nothing sticks out while everything is there. Nothing that would make me think about an amplifier. It simply amplifies and does not make me think about it. That may be the answer to...
Maybe the answer is not about magic but about the priorities and personalities of Luxman owners. Luxman marketing department may have answers.
Comparing it with anything else may not be easy on the Internet. Auditioning would go much further.
