If you set up Magneplaners correctly, they reproduce what you send them.
If that is your idea of "reference" then so be it.
Try playing a musical instrument live--a piano, possibly, as they are somewhat difficult to record--and then play the recorded version.
If you don't hear any difference, either your ears are not trained or you have a pretty good system, I would say.
That's what Maggies do if your system is not weak in some area.
Try it and see for yourself, of course. Don't take anyone's word for anything.
Cheers!
