Here is a perfect example of some people liking the addition of gross distortion to their systems.
These distortion synthesizers have useful output down to 10 kHz which is audible and will make a system sound brighter. If you have good loudspeakers, falsely brighter. But people who do not know what they are listening to prefer this. However, it is a fine way to destroy accurate imaging. But, most audiophiles do not know what accurate imaging is. They have never heard it. They hear an instrument over here and a voice over there and they think that is all there is to accurate imaging, not. It is very difficult to describe. The term holographic is used incorrectly. You can not see around (through) an object, well maybe millercarbon can, but you can hear around an object. With the best imaging there is space around the instruments and voices and they appear in perspective to one another and not just overlapping. Accurate high frequency ques are important for this to occur and an overlapping supertweeter will distort them. But, you don't know what you are missing if you did not have it in the first place, very few systems do. Brighter will always seem to sound better within limits. It is a trap which takes you father away from the absolute sound.
The addition of complexity to loudspeakers is always a bad thing. The Dahlquist DQ10 is a perfect example. From a tonality perspective they were wonderful but there is no way you can get them to image properly. They were very complicated speakers. We tried with a friend's pair for 3 years before he gave up and bought Acoustats which he used for the duration of his life.
"Want your digital to sound like analog?" Give me a break. Red Book CDs are quite capable of producing 10 to 20 kHz and that is all you are hearing if you are 19 years old. If you think what happens over 20kHz matters you have some learning to do. This is just like guys arguing over who's car is faster at speeds you can not drive at even on most tracks, not to mention most guys would wet their pants in a car going faster than 160 MPH. Speeds you can't drive at and frequencies you can not possibly hear and have zero effect on the audio band. Mysticism does not belong in audio. It is not a religion.
