Both Mac and Luxman are good gear. I doubt you're going to hear significant differences. Certainly not worth what it will cost you for the Luxman, plus the pain of selling off the Mac.
Do you enjoy what you have now? If so, be happy with it.
Me? I wouldn't buy contemporary Mac gear as I don't think it's a good value. Same with the current line of Luxman either.
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
