Hello, I am thinking about purchasing the Grado SR60i’s, and I would like to create a CD that has various audio qualities including different songs. To test, I will create a CD with several songs one as a WAV, MP3 at various bit rates. Basically a sampling CD to test the headphones how they sound at different qualities. Is this possible to do? I would like it to work on CD players. If so, what must I do? What software? I thank you for your attention and responses to this thread.
