Nice article. It's funny that all the digital formats mentioned above are in agony and the LP market is still growing. Nobody can predict that
I never listen to a DVDA or SACD in my life, i have a few but I only played the red book layer. However if the vinyl community is still gaining more members I don't think that this hi res formats are better than the ol' black plastic ones. But I think the reason why vinyl is popular with the kids is because it is a cool object nowadays, this may change in a few years and it will become again a niche market.
But, WTH, let's enjoy this moment, try to buy as many records as we can, and long live LP!
