RE: Can air & space be an artifact?

Tubes are not the only devices that get air and space; however, they do the 3d palpabilty making images that are far more lifelike in terms of volume, which has a definite impact on realism...when designed properly. When not, they can seem just as flat as transistors.

My theory is that with a well designed tube you have less high order harmonics (at least at moderate powers where most listening operates). Now why should this matter? Because high order harmonics affect the perception of loudness. They have the effect of make things sound louder than they really are.

Now why should this matter? Well the perception of distance for a raditating object is partially related to the relative loudness of different frequency ranges. Highs are more readily absorbed by the environment and so sounds further away have HF at a lower level than when you are close to the instrument. Now, if you muck this up by making the highs sound a bit louder then you also make them sound a bit closer. This then modifies the soundstage during playback. In the extreme, this will give you a flat soundstage with flat images. I have heard combinations that give soundstage depth but image roundness is still non-existant, suggesting that this aspect is even more subtle than the room soundstage.

If you suspect that this is an artifact I would sure like to hear your hypothesis as to WHY this should be an artifact and not simply a better decoding of recorded information.

You do agree that the original players and singers that were recorded were three dimensional resonating objects, don't you?
