Tough choice--agree that it probably depends on taste and synergy. It's kind of hard for me to imagine the lowest tier Luxman beating the penultimate Hegel. I had the H390 and currently have the Luxman L-509X. While I think the Luxman is the better and more natural sounding integrated, the Hegel comes pretty close on technical merits, and it just may be a matter of preference. I heard the L-550AXii, and while certainly musical and enjoyable, I felt it lacked the depth, detail, and precision of Luxman upper end amps to a noticeable degree.
