are digital recordings on vinyl any better than CD

Analogue tape is the best medium there is. If the deck is up to the task and you use better tape, talking reel to reel, except for extra noise the recording will overall sound better, with more natural flow and drive.
To paraphrase the immortal expression - it's the tape stupid.

@inna "tape stupid" is a good one! Thats Exactly how I feel about analogue sound! As a professional "academic researcher" I've learned not to trust others folks findings until its been confirmed, and this topic of digital masters onto LPs bothers me A Lot! I did spend my Christmas present on the latest Wadia SACD player a few years back but it still could not beat my Sondek... dCS stack is out of my reach (well, unless Allah will "smile on" my business! ;-) ) so until then I say that analog sounds the best. As I mentioned elsewhere, having half-decent analogue rig will make you bitching about AC noise and sneezing neighbors at LA Opera. Disclaimer: just getting to LA Opera is a torture with all the traffic, so my say on Live vs Canned music is totally skewed! 

Inna you are correct, tape sounds better; you have 2 track or 1/2 track which records in one direction only, and you have 1/4 track which records and plays back in both directions.

2 track that records in only one direction is very expensive in regard to tape, but whatever you record will sound much better; your speakers will appear to have gotten larger. Since I have tape from the time it was cheap, I can enjoy that luxury.

As for the original question, I will have to experiment before I can answer it, but it seems to me that you would have a multiplicity of variables to take into account.

First, digital sounds better than cheap analog; therefore the bottom line depends on the price of the unit; that's where the multiplicity of variables come into play.

You can only get what is on a vinyl record with the right rig perfectly set up.

Analog people seem to think you can get that sound with a stock "Dual" turntable that comes with arm and cartridge. I'll take the CD any day over that.

Hi SEVS:
I remember a number of years ago (about 4) at a NY audio show, an exhibitor pitted the DCS stack against a Top end Basis audio tt with Lyra Titan on the same system to prove that the DCS stack was in the ballpark with the tt in terms of SQ. Most listeners walked out as I did thinking it was a great way to promote the Basis table with Lyra cartridge. It was not that close.
