LUXMAN 505u?

It was 2016 but that post you quoted did not say L590AXii (missing the X). All of the historic models have similar numbers so can get a bit confusing.

I actually researched the history because I’m really interested in L590AXii but it is overdue to be replaced based on release history, which is:

2005: L590A
2010: L590Aii
2013: L590AX
2016: L590AXii

So in last 20 years the longest between models was 5 years (two most recent revs just 3 years), and we are at that 5 year mark now since release of current model. So kinda torn on what to do....
