So that begs the question, what is the part (or parts) of your hifi system that is causing the change. It may be that you are in a perfect position to find this out as you can stand on both sides of the line. So to speak.So, using your response, highlighting why there might be a discrepancy, I conclude that my, and most everybody else’s hifi may not be reproducing what the engineer, mastering engineer, or producer intended.
Likewise how does a commercial recording sound if reproduced by both your studio and hifi system?
