Recently I have been purchasing Hi-Def files from Pono and a few other places. I just purchased the new remastered David Bowie - "The Rise And Fall Of Ziggy Stardust And The Spiders From Mars (2012 Remastered Version)" and it is 24 bit with a 192000 sample rate. I see Roxio NXT 3 doesn't support 24 bit. Does anyone know if NXT 4 supports it? For now I have been using Goldwave to convert to 16 bit. BTW, I want to burn these files to disc for my vehicle's 5 disc carousel.
