Many are migrating to all digital streaming and hard drive, and there is no doubt a good DAC can extract a lot of detail and make a great system. But the problem I see is that, because everything is at hand, your listening changes too and you just jump around rather than listening to a CD/LP that often the artist put a ton of time into to create a musical arc. It’s instant gratification time. So I still prefer to keep my CDs and Vinyl as physical music I put on and play through.
So, like some other posts have mentioned I’d keep both the ‘shiny spinner’ and digital hard drive. Like you too I have a few SACDs but given there all but one playable as CDs too, opting for a new SACD is probably not the ‘best’ option. So it all comes down how you listen and interact with your music collection, but I’d buy the DAC and see how it all sounds before ditching anything!
