@SOIX the zen is an integrated. But I am using it as an amp with 2 inputs. I have the volume knob maxxed. for 2 channel I use my Lampizator GG3 dac as the pre. For movies, the Denon preout for the 2 front channels drives the Zen.
This weekend, I think my new bespoke custom amp will be delivered and the zen will get a break. I've really become attached to it. It will be interesting going from an $1100 amp to a 6 figure amp.
