I'm a 'vinylista'...at home I listen to vinyl 99+% of the time but I have to agree with the OP's thesis.
When people ask, I tell them that if you have less than $5k to spend on a source, go with digital.
$5-$10 is a push for sound quality, especially factoring in the costs of extra cables and a quality phono preamp.
Above $10k, you should be able to get better sound quality from vinyl and at the extreme fringe, it's really no contest, analog is better....
But (and there's always a but), that's if you have the patience to do a quality set up (many ?most? expensive analog systems are not well set up) and are willing to spend the money to get quality software. These caveats should probably give significant pause to the vast majority of folks contemplating a greater than $5k expenditure.
