Demagnetizing CDs?!
Techmoan・2 minutes read
A device claiming to demagnetize CDs to enhance sound quality was reviewed, despite skepticism about CDs being magnetized. Testing showed no difference in sound quality before and after demagnetization, leading to the conclusion that altering CDs is unlikely to significantly improve audio quality.
Insights
- The Acoustic Revive Audio Demagnetizer RD3 claims to improve CD sound quality by demagnetizing discs, despite the general belief that CDs cannot be magnetized due to their aluminum composition.
- Testing revealed no difference in sound quality before and after using the device, suggesting that altering the content of CDs through demagnetization may not significantly enhance audio quality, challenging the popular belief in the effectiveness of disc demagnetizers.
