Are there any opamps onboard or is it just the resistor network?
Sorry, I didn't see your post until just now. I'm sure you probably found the datasheet by now, but if not:

What are the most sound quality solution for a potentiometer as 'Passive PreAmp' ?

Did anyone comapre some solutions ?

There are :

1. Potentiometer like ALPS (motorized)
2. Relay based Attenuator with resistor array
3. IC based volume control

It should be possible to remote control the volume, so i exclude the switch based solution which is near to relay based solution (?)

Thanks, regards

That doesn't really make any sense. But, have you tried a buffer before or after the volume control? That might localize the problem.
