Can you rephrase please Gerard ?

Upsampling *and* using the Digital Volume Control should really not be applied together !     

Expectations on changed sound quality : totally different from before.
But if you don't want that, keep everything connected as usual, and set the Volume Slider (topmost) to -0dB. Sound will be the same as before with 16bit files.

For me it's confusing just the same Gerard.

When you ticked Double and it playes, you should be fine. Also, that info screen (3rd) shows the native file data.
Whether this is better for SQ is up to you. YMMV here. But you can try now !

I am playing regular 16/44.1 cd ripped files.
What I was saying refers to settings area, "DAC is 24 bits 192.0 KHz" combobox not the track formats.

Gerard, you said the room is separated from the music now. This one didn't occur to me, but I think you are right. How ? what actually happens then ?
Maybe this "room separation level" is something to work with. But then I'd first have to listen and pay explicitly attention to that phenomenon.

Possibly this is not a separation from the room, but a separation from everything. I mean, it already occurred to me (and I really wondered) why I was closely listening to the music quality itself, french fries boiling in oil making a havy noise right behind me, the cooking hood at full power ditto ... and I found myself rathert explicitly thinking "I don't care !". Normally I wouldn't even start to sit down and listen seriously. So ...

... Concentration level. Ah, that seems a good one ! And mind you, it already exists in our world of audio. Maybe it's not very well defined and spoken of, but I think we all know about *or* your attention is with the music *or* you find yourself thinking of something else while you should have payed attention to such and so, and now the moment has passed.

Interestingly enough it -then- is this same concentration level that allows you to NOT pay attention to the music. To me this is almost more strange than being able to concentrate on the music. Like I told about it in the previous post ... typing stuff like this and during such mind setting there is just *no way* I heard music. Room separation, subject separation, concentration separation.

Officially it wouldn't help, but let me repeat at this stage that I told about CD Playback always having been wrong as I see it. So now I do it right. Just right, that's all.

Might this be similar now to the natural realism of you being in a room with 30 people, two people opposite of you with a table in between and you talking to those people, while right behind you -closer than the people you talk to- other people are talking, and you are not disturbed by that at all ? you are able to concentrate on the people you talk to. The others talk louder, but actually you don't hear them. You hear the people you talk to.
Now compare the same situation, but music plays. I think we all know, it doesn't need to be loud at all to disturb. Why ? is this because it is so much unnatural that our brain can't get it out of the way ?
Note that I don't have the experience yet of playing music at this birthday party, but that I feel that it won't harm anymore.

If I'm on the right track, is "naturalness" a property ? Ok, it could (or should !) but as an ICTer I say this is an inheritent and composed property of many other properties. So, useless. Naturalness could be way to describe the sensation though, but on the other hand ... what defines naturalness then. Me ? nope. We rather need that property that defines naturallness. Like "concentration level" is prone to it (I think).

Possibly this is not a separation from the room, but a separation from everything. I mean, it already occurred to me (and I really wondered) why I was closely listening to the music quality itself, french fries boiling in oil making a havy noise right behind me, the cooking hood at full power ditto ... and I found myself rathert explicitly thinking "I don't care !". Normally I wouldn't even start to sit down and listen seriously. So ...

What I hear in really everything is a perfect added sound that came from under - upwards (in dutch : van onder uit). Like base tones were lacking, and *those* are added now. Can this be ? hardly. It more looks like the proof that undertones actually do exist and that *those* are able to be profound now (similar to just everything is more profound). Whether they are in the recorded data or are recreated in air ... I don't know at this time.

but it is the very first time in my life that this whole evening the music is playing (not loud) and I don't even notice it while being behind the computer screen.
