1) If some people are uncomfortable setting up a turntable or unsure of the process, it can be done for them either as part of the sale of a new TT or for a reasonable fee afterward, and many turntables today are virtually plug’n’play systems that don’t require skilled set-up. Once it’s set up, it’s generally no more finicky to use than a toaster; and
2) In a modern system, the wear to vinyl is minimal even over hundreds of plays (or are you still thinking of a cheap plastic turntable with a penny on the headshell? We’re WAY beyond that today) — and what would you rather have, mediocre digital sound forever (or until CD rot sets in), or great analogue that wears, after many plays, to merely excellent and still simply beats the pants off digital?
As for SACD and DVD-A, the former has problems with frequency-dependent distortion (much of that supposed added “clarity” is distortion, especially on cymbals and violins; Robert E. Greene has written extensively about this), while the latter is a dead in the water format; neither appear to have the legs to achieve consumer acceptance in the marketplace, particularly in their multichannel iterations, and Sony has all but abandoned their own SACD format. Decades hence SACDs and DVD-As will be, at best, drinks coasters, while LPs will still be playing beautiful tunes....
Whatever form it takes...enjoy the music...there’s tons of it out there!
By the way, I think DVD-A will continue to survive because unlike SACD, DVD-A's can be played back on many computers with DVD burner drives if you have the right sound card and software. My computer can play back DVD-A's and the recent Beatles Love album on DVD-A sounds really good.
