I'm sorry guys, once more, here another example of a (German) high-end manufacturer of tube electronics who refers to 3D imaging as a quality factor.

Quote: The EK***SE is a true class A line stage pre-amp. Designed for the audiophiles who want pure analog with the highest quality sound available, without the price of one.
The quality of sound is a dream come true, with a true 3 dimensional sound. Where the depth of instruments and their location, the warmth and transparency puts you in a world where only few have been. You will discover that your music has details that were held back and now are being revealed.

It is striking that many manufacturers of tube electronics use this 3D "quality" to underscore the stregth of their products. Question: is referring to 3D quality in fact a marketing trick?

Not in my experience with (most) tube gear in my system.

How do you know when something is a marketing "trick?" Until recently I have found many tube amps that give a great sense of having depth to the image. Some were more able to have depth on the sides while some only had it in the center.

Some ss amps, such as the Cello and the little 47 Labs 25 watter did not have as much depth but retained in on the sides. The Exemplar had great depth in the center but less on the sides.

I guess I would agree that there was greater probability that tube had depth to their sound stage. But that is not the issue.
