Two years ago, I have come across an article written by Gary Leonard Koh, CEO of Genesis Loudspeakers, how Black CDs improved the sound of audio CDs. I had the privilege to personally met Gary because he is a former house tenant of my sister Daylinda here in Cebu. His white paper, In Quest of Absolute Fidelity: The Saga of Black CDs, (click here to view and download) details the process. I tried to copy some of my favorite selections to Black CDs. Lo and behold … I find the imaging (the location of the instruments and performers) more defined and the space acoustics somewhat widened even with my modest stereo system. Now, I end up copying almost all my original audio CDs into Black CDs.
