Having 24-Bit Sound or not

I downloaded BitPerfect this week - easy install, with a good online manual.

I noticed a more dynamic presentation with better detailed highs and better sivilance presentation - I assume this is because there is no up sampling taking place.

I wanted iTunes to stream just the content of the music file whether it's 16/44 or 24/96 and that is what appears to be happening - not as before where iTunes streamed everything at 24/96 according to the readout on my DAC

And only $9.99 from the apple store

:-)

I've since changed to Audirvana since it bypasses all of the Apple software and provide a significant improvement in audio quality over BitPerfect
