But is "great vinyl sound" really old-fashioned? While I have not been an audiophile that long, I doubt the sound of what is called today great vinyl is the same as what it was 30 years ago. I know my dad had a good sound system, he actually still has it, and the sound is not very good by today's standards. But it was amazing back then.
As someone mentioned above, the improvement pace has been slower in vinyl than digital, but vinyl seems to have improved too.
Also, Tvfreak asked in the OP if digital was "just" convenience, but I don't think about convenience just as a potatoe couch syndrome type of thing. Carefully setting up an extremely accurate vinyl rig is no minor task, requires multiple devices/gadgets (just like digital?), and significant maintenance. Of course, the potatoe couch aspects also have an impact: not as easy to get the media to your hands, and then playing them.
I've chosen not to pursue vinyl since my budget is limited and would rather pursue one avenue and do it right. I run only a computer-based front-end, with tubed pre and tubed amp, and the pre has two volume pots and no remote - hence my differentiation between the flavours in potatoe couchness ;-)
Still this discussion is very interesting to me as I've always kept vinyl as something I might want to pursue some day.
Cheers!
