Dumb question?
Why is anyone (still) spending large sums of money on Compact Disc.
And, why are we (still) debating snake oil treatments to make them tolerable?
Pretty much the same reason so many audiophiles still have a love for vinyl and enjoy periodically adding to their collections and spend good sums of money to buy nice gear to play them.
Nothing so snake oil about most of, or at leas a good share of, the products we use to clean and take care of our valuable collections.
To each their own...Jim
