Luxman Integrated - What do they sound like

Wanted to give my piece to this. I just brought home the 509X for an in home audition with my Spendor D9's. The amps that I have heard for a reasonable amount of time include my own Line Magnetic 805ia (with NOS and fairly pricey new issue tubes), Hegel 360, Primaluna Dialogue Premium HP Integrated (which I had for about 2 weeks at home). 

The Luxman's build quality is easily the best that I have tested at home. It looks like it was meant to last a life time and I would expect it to given how well built it is. It is also very nice to look at. The sound is what is more important though and I think this is worth delving into a bit more. In my system, with my components and speakers, I enjoy it as much as I do my Line Magnetic save for some of that magical tube quality that I can't quite pinpoint. It is above the Hegel I heard with Magico A3's and the Primaluna Dialogue Premium HP which I had at home for a few weeks. Dynamics, strength, effortlessness are all words that I would use to describe this amp. Great extension at both the high and low range. The midrange is so smooth and yet accurate at the same time. Tight low end bass control was evident upon connecting this amp to my system. I could be perfectly happy with this amp for a long, long time. I am curious about the Class A 590AX II however and would like to try that out before making a decision but it is likely that I will be getting a Luxman soon. 

@erik_squires It is Accuphase that is a lot more expensive in the US than Luxman. It used to be that Luxman was quite a bit more pricey than in Japan as well but following a change in the US distributor, the prices came down quite drastically. 

The 590AXII that I have tried at home for the past week with my Spendor D9's warms up fairly quick. Even at peak though, the heat is really not bad at all. I can keep my hand on it so that may tell you something. It is a great sounding amp - one that I like over the 509X but that's me coming from a tube setup. 

@arturgorniak Nice set of amps that you have been through. Not surprising that the Luxman 509x topped your list. It is fantastic providing vibrant, dynamic, controlled sound but is also a great all rounder. An end game amp for a lot of people.
