LuXman 509u for my Sonus Faber GM

Guys, I am going to buy the L509u for my new SF GM soon, any last comments & advices?
That should sound very good. 509u are very good amps.
It should sound outstanding!!

Post your impressions once you have it.
Depends what you want your amplifier to do...I have 509U and it's outstanding, but it is not the fastest amp in the world so unless you want your SF to get up and start sprinting, you'll be pleased.
Thanks, since I am in China and need to find a right dealer to get this amp....TBC
