Very nice. Especially for a first hi-end system.
Before advancing with any upgrades, etc., I would suggest you entertain some dedicated AC circuits/lines for each component in your system.
And equally important would be some in-line power conditioners (instead of power cords).
Some will say if you are running dedicated lines, then you no longer need to concern yourself with power conditioning. But that simply is not true. At least in my case it's not true. And I live in a quiet residential neighborhood (no power plants or major industrial facilities nearby).
You might be amazed at the sonic improvements such in-expensive tweaks like this can make.
-IMO
