And that may be part of it, but it's not quite all of it. Our ears are just incredibly fine analog instruments, and the digital world to date - at least the mass marketed digital world, just isn't up to that quality. So far they aren't. They are certainly easier to care for, they're sturdier, and you can't beat the form factor compared to vinyl. It's kinda like transistors and tubes.
Transistors make more sense in every way.
As much as I like my Peavey Heritage VTX, I'm really enjoying playing that Silverone tube amp through the VTX's cab. The sound is definitely fuller in most cases, enough so that I rarely whine about having only 1 tone control per channel. It's a more honest sound, too, forcing me to play better. It's easier to get more variety out of the strings. Bizarrely, my left hand doesn't cramp as easily - so I must even be playing differently.
