I did read your post and I was hoping that others who are on the fence to upgrade their desktop to a new machine, read the options that I was suggesting. Because if they are in the similar situation as you were earlier, they could upgrade their existing installation and still use their old DAC. People have reported on the Windows forums that after using Rufus to upgrade their Windows 10 to 11, they are still are able to use legacy devices.
Also, I stand by my comment on analog Vs digital. I suggest you check out Audiophilestyle and see the depth of digital knowledge being discussed on that forum. I have been on this site for 2 decades and have high respect for the well known members and the newer members members who are respectful to others. But the depth of digital discussions that go on the Audiophilestyle site (whether folks like it or not) is at a completely different level.
BTW, what are the components of your $50k system? Would love to see that, if you can post some pics.
