Luxman L-509X

@rpeluso Me too owner of 509u.
Are you from Italy, isn't it?
I am not sure 509x can better the 509u, our amp was built with another kind of attention to perfection.
If I had to buy an integrated today (I will never change my 509u) I would buy a 509x without esitations anyway.

@pokey77  I was sure 509x destroyed 590AXII ... no dynamics, no image, no extension ... only midrange bloom!

509u has no roll off.
Maybe it was a choice to make the new integrated "easier". 
509u was a "no compromise" machine, you had to work hard to find the right match with source, speakers and cables, it was very high sensitive to electricity quality and line phase... it was not an integrated "for all", but I like this way, the way of real hi-fi.
