Pass X1 preamp question

Has anyone noticed if they find a sonic difference by turning off the display of their X1 or other preamp? I just noticed today that perhaps the music is quiter(less noise) with the display turned off.It's like turning off the display of a CDP but to a lesser degree. I'm just wondering if pass put the option to dim or turn off the display for sonic purposes? Any opinions would be appreciated.

I hear a slight edge off the top removed with the dimmer down. I know the digital circuitry is seperate from the analogue and the difference I hear is very subtle yet it is there. Not enough to have me dimming down the display all the time however. The difference is slight. A very touch more snap in the highs.

I have an X0.2. I can't hear any difference with the display on or off. I usually keep it off just because I find it annoying when I am listening in the dark.

Apparently it's psychoachoustical and being very suggestive by nature there appears to be a difference but there is none in reality other than what I think I hear. I love the preamp.

Sonically, I think the X2.5 and the X-1 are outstanding pre-amps at least with my line conditioners attached to them.

What I do not care for is their somewhat crude remote control interface and the lack of incremental attenuation for fine-tuning volume levels.

But still outstanding products and company.

-IMO

Steno, How do you find the Pass preamps compare with the Chapter. I see you use or used one in your system. Personally I think the X1 sounds quite good but I'm curious about the Chapter for curiousities sake.
