You might as well ask why there are no horses and carts.
@clearthinker Yes, those are ancient technologies. And that’s my whole question, my wondering ... how come there are still ancient technologies like tubes and vinyl in use in the audiophile world, while there’s no such trend in the videophile world? If it sounds nicer (to avoid the word better) then maybe a TV set with tubes could also look nicer? If there’s a market for ’audio fuses’ because they make it sound nicer ... how come there are no ’video fuses’ that make the picture look nicer? Apparently there’s no market for that.
