Hi all,
Don't get all worked up over 192 kHz/24-bit data rates. Although DVD-A supports this, if a music producer selects that rate, it limits the number of channels that he can use, so few if any DVD-A's are mastered at 192 kHz. Moreover, the thermal noise generated by solid-state circuitry exceeds the theoretical advantages of 24 bits (6 dB x 24), which in theory would yield a 144-dB dynamic range. Impressive, but not practical. What happens when your furnace blower or refrigerator cycles on? So much for usable dynamic range in a domestic environment.
Regards,
