I believe the problem lies in the "Studio Monitors" that a lot of recording studios use to master music. Honky horns, with no top end response, and very little accurate bass. So, they mix & equalize so it sounds good to them in the studio. Play it back on a decent hi-fi and, presto! - ear-bleed stuff with lumpy bass. I recently had a talented session musician friend of mine over to hear the new song he had just recorded in a New York recording studio. Offered a very rare opportunity, I asked him if my system played back the song as he heard it in the studio, true to the artist's goal. He said, "Nope. I can heard all of the production mistakes on your system. We couldn't hear those in the studio. " I offered my home as a master listening place for his next recording, before the final mixdown. Sweet.
Swelled head & all, I remain...
