Solid State. I just prefer the SS sound with the HD800S's. They sound really dynamic with it. In tube mode, the dynamic edge is softened a bit and you do lose a little treble energy but to be honest I have no problem with the HD800S's treble response.Just to make sure: Which branch of the iFi Pro iCAN do you use, the SS or the tubes? When do you experience the nice synergies with the HD 800 S, one of them or both?
From your gear list I see you have the Hugo 2. What are your experiences with the Hugo 2 and HD 800 S, without the iCAN as compared to with it?
The HD800S with the Hugo 2 I have yet to try the pairing on it's on. I do use the Hugo 2 as my DAC for the Pro iCan and they are phenomenal together. The reason being is I just prefer listening to the HD800S's with XBass+ on in balanced mode. Other headfiers like the Hugo 2 and HD800S combo I just haven't listened to them that way but I will try it.
