The Luxman would not be a reason for concern ... the Bass should be good.
BHK 300 vs Luxman m900u vs Mola Mola Kaluga
Looking for insight on sound comparisons between these three amps. Had and liked the BHK’s, but returned them due to ongoing QA issues. I’m concerned about the bass capability of the Luxman, and about class D sound from the Kaluga. Have heard neither, and can’t get a demo.
