are digital recordings on vinyl any better than CD

This subject was discussed before though I don't quite remember where.
The short answer is, yes, it still can sound better on vinyl. How much better? It depends, including on your equipment.

I'll give you an example. The album "Passion Grace&Fire" by John McLaughlin/Paco de Lucia/Al di Meola. Digital recording,mastering. The year was 1981. I have it on Japanese original Mastersound CD, Japanese Mastersound DSD CD, Japanese LP, American LP. The best sound comes from Japanese LP followed by Japanese DSD CD. American LP and original Japanese CD sound about the same. I would guess that though my analog rig is better than digital it is not by much. So it is possible that if you put that DSD CD on EMM Labs player or something like that, it will sound better than Japanese LP on my Spacedeck, but that would not be the point.

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.

Orpheus10, I will both agree and disagree with you about Dual example. In some ways Dual would still sound better with a well-recorded record than any cd system but overall probably not if that cd system is excellent. I have bad sounding records and good sounding cds, which ones sound better ? Overall, probably good sounding cds, and my analog is higher level than digital.
To return to the original subject, in my very limited experience digital recording or analog recording/digital mastering on LP sounds like best cd I could get. Original Japanese record beats any remastered or original Japanese cd. But again, my analog front end is pretty good, though CEC belt drive player is not bad at all. 

Orpheus, there are quite a few places that service and repair reel to reel decks, some are very good, as I heard. No, it is not inexpensive but nor is it necessarily very expensive. Tape cost will depend on how many of reels you need and the speed at which you record, of course, assuming two track in any case. And you can get Otari deck in apparently good condition for about $1000. I am just not ready for this project yet but I'll get there in time. 80% of my listening is tape, Nakamichi 682ZX with Maxell Vertex cassette, 10% - records and another 10% - computer. I virtually don't listen to cds, I record the tracks I like onto the tape and listen to compilations. And I have my Nak serviced and aligned every 5/6 years by Willy Hermann in California.

Orpheus10,
I appreciate your gift, thank you, but unfortunately I'll have to decline.
As I said, I am not ready now for reel to reel project, and when I embark on any project I try to do it right. In this case this would involve going all over the deck, servicing and aligning it, in addition to fixing clutch and whatever else might be close to breaking.This would be quite expensive but worth it. Besides, I was thinking of highest performance, that's two track deck. And I would need at least twenty or so reels plus good balanced cable to get it going.
Perhaps, you could reconsider and have it fixed. You play tapes a lot. I just don't want to imagine it being thrown away. It's good machine, it doesn't deserve it.

Tape is the only true audiophile medium, in my view, and it shows even when the original is not tape. I am not surprised at all. But you do need good reel to reel to fully appreciate it. Cassette has its limits, and I think I have reached them.

As an additional note, I have one Vertex cassette that I played probably 500 times, and though mechanically it does show age, it sounds just as it did the first time. Try that with any record on any turntable. And I keep playing it every week or so. But I almost never rewind or fastforward, that's how you wear tapes. And I clean playback head about every ten hours of play.
