WBF = What’s Best Forum - much deeper pockets- they discuss through experience up to the very best audio components.
Usually, Luxman is paired with speakers costing roughly up to 20k. If you get a top speaker, like the Magico M3, then the Luxman would be the sonic bottleneck. It’s best to have a balanced (near same level, minimizing bottlenecks) audio chain including cabling.
Also, be careful not to get speakers too large for your space that may create excess bass issues. Too small speakers may not be enough to pressurize the room- if that is your goal.
Good Luck and Happy Hunting
