I'm probably a little late with this, but I was going to suggest doing some tube rolling in the MA252 and see if that helps give you more of what you feel is currently lacking. I haven't yet done it myself in my Mac tube preamp, but have read many comments about it. Seems many folks feel the stock JJ tubes are not the best to bring out the full potential of the Mac tube gear. Improvements in soundstage, bass and "top-end sparkle" are often mentioned.
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
