I approve of this approach as a trained physicist! Can you recommend a place to buy an album for download at >=96khz/24bit? I have a topping DAC which has a USB input, so I could go from laptop to DX7s . I purchased the DAC a long time ago, but I am not sure how much difference there can be in a newer/different model. I do know that I prefer the sound of my Marantz CD 63 mkII, through it’s onboard DAC, rather than going through the Topping and using the marantz as a transport.
No idea why you are down voted? You make a lot of sense ! I need to educate myself on ‘REDbook’ as the terminology is new to me. The marketing here reminds me of minidisc; I had about four players, a deck at home and one in my car. They actually sucked, as the floppy disc style enclosure filled with dirt. They were also responsible for my best friend’s worst car accident - I had given him my collection when I moved onto the creative labs ZEN mp3 player, my handwriting was so bad that he drove straight over a roundabout trying to find a metallica album 🤣
