@ossie62 Thank you for your comment. Rather than a neophyte, I am a former shop owner who listened to horns and every other type of speaker available, including electrostatics of every manufacturer, planers, boxes, and even some hybrid designs of all of these reproduction formats in my shop for LONG periods of time with many different pieces of electronic gear. Now, that was a while ago, but physics do not change much over the years, especially those involved in playback of recorded music.
THEN, when we set up instruments in the shop and played them to hear the differences between live music and recordings, we learned even more.
Finally, one of my many bands that I played in recorded in a studio, and THAT was a learning experience if I ever had one in this field.
Recording engineers and the equipment they use have a lot to do with the sound you get on playback. Obviously, the room you listen in has a significant influence on the quality of your listening as well.
What we found was that even though horns were loud, they clearly distorted human voices and SOME instruments when listened to with well-recorded music--we liked the Lincoln Mayorga direct-to-disc vinyl in those days, which have some issues, but were better than 99% of what was out there.
If you put the two side-by-side and listen to a variety of music genres with pretty good equipment, you will probably discover what we did. Planers are not perfect, but they DO reproduce what you feed them as accurately as a reproduction device can. A live violin or female voice will be helpful as well in hearing the differences if you can arrange that like we did.
Having typed that, some people LIKE the horn sound, and more power to them. We sold you what YOU liked and put the money in the bank; it is called business,
But after years of listening and playing and going to live concerts of every genre in many venues, we found that the most accurate and pleasing reproduction for long-term listening was had through planers, with all their "faults" that you point out and I disagree with, but that is what makes audio so much fun!
Cheers!
