OK, I give up, but thanks for the info.
I enjoy what I have and use and that’s all that’s important to me. If I were “20 something” again, I might be more finicky.
If you’re older your ability to hear above 11 KHz is likely diminished, so you wouldn’t be able to tell the difference anyway. Otherwise, the quality of your audio system comes into play, and a lot of car and computer speakers can’t reproduce CD quality, so you’d never notice there either.
