Great response Craig! It's the same as a car. The speed limit is 65, so why get the Turbo V6, when the standard 4 cylinder will get you there.
What's the use of 20 and 24 bit DACs with CDs?
Many standalone players and modern DACs are now using 20 and 24 bit DACs. Is there a significant advantage to doing so with a 16 bit recording? Are these players and DACs doing upsampling on the original 16 bit signal to take advantage of the DAC or are we just looking at extra bandwidth that is being squandered for the sake of advertising? To me, the extra bandwidth doesn't seem to be merited unless there is upsampling or HDCD involved. Opinions?
