(sorry its in English.. there is no X40 or Cocktail Audio Forum in Holland)

Hey There,

I also have an X40 and wondered how the digital preamp volume is working.
Do I lose some bit depth when the volume goes down?

Greetings from Holland

It does not have any effect on bit depth. Digital volume is controlled by hardware chip(Sample Rate Converter : SRC4392)

Ok thanks voor this useful information.
