An interesting hypothesis, Ron and May well be true for some true full horns (although I would put the divide more with all acoustic music on one side that has less processing and highly processed music on the other), which simply expose heavily manipulated/compressed recordings for what they are. Keep in mind a lot of great pop/rock was produced on hybrid horn type speakers from JBL, Altec and Tannoy and likely those speakers will do justice to a good rock recording.I am somewhere in the middle. I think that there actually can be a lot of agreement in audio, subjective though much of it is.
Keith asks, essentially, “if horns/SET is so great why don’t more people make it and more people use it?”
I believe strongly that musical genre preference substantially drives loudspeaker preference. If we narrow the musical genre preference to jazz I actually think that a lot of individual subjective preferences would coalesce around a plurality view that horns/SET is the most convincing way to reproduce jazz music.
I personally believe that there is something about the way horn loudspeakers reproduce the sounds of brass instruments which is consonant with the way brass instruments themselves produce their sounds. If people who have experience listening to a lot of different types of loudspeakers hear jazz reproduced by horns/SET I think there would be statistically significant agreement.
If someone’s musical genre preference were mainly rock, or if someone’s musical genre preferences were equally divided among the main genres of music, I would not select for that person a horn/SET system.
I would put planars, especially electrostats on the acoustic /less manipulated side.
