Has digital come close to or beat up analog yet ?

i had a great experience with japanese red book CDs that do sound better than same album vinyl made in japan.

As I stated above, I think digital has evolved to a point where it's largely a matter of DIFFERENCES between the two formats. Sure, analog does some things better than digital, but digital also does some things better than analog. The best of the two formats are overall pretty equal in my book. In my time as an audiophile, I've either owned or heard the best turntables and digital playback devices out there, and I don't agree that, with a good LP, analog "walks away" from digital. A well recorded CD played back on a quality digital rig can compete with equivalent analog any day of the week. It's mostly a matter of what type of sonic presentation you value. I own an EMM Labs setup now, and I could've easily bought a SOTA turntable, but I didn't feel that the difference in presentation I'd get was worth the hassle. The EMM does everything (and more) that I need it to. Just my opinion.

i dont think there is digital unit

HeHeHe... you said "unit"

NO

How do you get a smoother analog wave with straight lines?

"Beat up?" Well, no. "Provide at least as good music as?" Yup. The best of even redbook CD digital now is good enough that the rest of the system including the room and speaker placement are more important than "silver discs vs. black", IMO. And if the point of the exercise is listening to lots of recent releases, well, I'll take CDs any day. Of course, with my front end I would say that, wouldn't I?
