+1 @ghdprentice on the sound attributes of Luxman. I extensively demoed one of the Class AB Integrateds with Persona 7F speakers. I was all set to take them for in home trial, but was disappointed in the harshness and lack of midrange warmth. Unlike @ghdprentice, I drifted to the much more musial SS products from Audonet. I find Audionet very much more musical and delicate, yet full and dynamic. My thoughts continue to be that if I can get this sound without tubes, it is the way to go.
Any real experiences with a Luxman C900u and C10x?
I'm in the market for a new preamp and have the M10x and am leaning to the Luxman C900u or C10x. There aren't many dealers around me that have both for me to try and there doesn't seem to be much info on both online (i may not be looking in the right places 
)
