Luxman Integrated - What do they sound like

so......on the beginning I will say that I own 509x and got it in the trade from twice the price Dartzeel LHC208.
I had following amps at home in my system before I finally settled down for L509x:
1. Nagra Classic Integrated
2. DartZeel LHC208
3. Hegel H160
4. Hegel H360
5. PassLab INT150
6. Hegel H20/P20
7. Luxman L550AX2
8  Luxman L590AX
9. Shindo Monbrison with Haut Brion
10. Line Magnetic LM219a
11. Sudden A21SE
12. Ars Sonum Filarmonia
13. Ars Sonum Gran-Filarmonia

I used to own DeVore Fidelity Orangutan 0/96 but finally settled on DeVore Super Nines as being best fit for my room and music taste. 
Luxman D08u is used as a source and Audience Au24X cables across the whole system.

Ask me more specific question about 509x and I will do my best to answer it. 

@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. 

@arturgorniak I was wondering about the sonic differences between the 507ux and the 509x...if you have ever compared them.

btw, a quick update: the 507ux is a wonderful wonderful match with Dynaudio Contour 30's; I just replaced the Focal Aria 948's with the Dyns and love the results. 

I've got the DAC/AMP plugged into an Isotek Aquarius power conditioner.
