Because at long last digital, and in particular streaming can equal the very best sound quality available, which for decades has been vinyl. It can be done across the different quality levels of high fidelity. As an added bonus music is essentially free ($14 / month) for access to millions of albums.
I am retire and am ecstatic. I don’t have to constantly get up and can do research in my audio chair and just line up what to play next. I listen to music about three hours a day now.
There is nothing difficult about it, unless you want to make it difficult. If you already have a DAC… most contemporary CD players let you use them as a DAC. You buy a high quality streamer. You can plug it into a cheap wall wart wifi repeater so not to worry about running a cable. That is it. Download the app to your iPad or phone and go. Lots of folks here like to buy inexpensive streamers and play with their network to get better sound. But if you get a high quality streamer you don’t need to play with your network. I have a cheap Netgear router and my streamer sound as good as my high end vinyl setup.
