McIntosh to Luxman?

Hey everybody. I need some advice.  It's fair to say I've lusted over Luxman equipment for a few years now.  Something about Japanese hifi that just gets me. Anyway, one of the online retailers of new and used equipment has a Luxman L-507uX (not the mark ii) for sale.  I do really like the sound from my hybrid MA252 integrated, and it drives my Maggie 1.7s with ease.  Most of my listening is of the streaming variety (Bludesound Node/Qobuz), and some vinyl (Music Hall MMF-5). 

Here's my question: what will the Luxman bring me that the McIntosh isn't providing?   More refinement?  More authoritative bass? Better soundstaging?  If the answer is yes, then I may pull the trigger on the Luxman.  By the way, I can get a nice trade-in on my McIntosh, so my out-of-pocket won't be too bad.    Please weigh-in if you've had both McIntosh and Luxman gear and what your experience with both brands has been.   Thanks in advance!   ~ Jerry
