CDs can only store 16/44 because of the PCM format. If you want to test your DAC at higher hz, you can play some DVDs and the DAC will show more than 44khz.
What is the story with 24 bit masters 24/96 .
I received some new (old) re-mastered classical CDs that have "Mastered with 24/96 Technology" splatter all over the front cover and liner notes. My DAC still lights up that the CD is standard 44.1 redbook (MSB). Does this mean that the second letter in ADD is all that is 24/96 and the final product is sampled back to 44? Is there something else wrong? Are there really any standard CDs out there that play at 96 Mhz ???
