Ralph, would you name those turntables you mentioned that were competent and sounded similar ?Kuzma Reference, Atma-Sphere 208, Technics SL1200 GAE with Triplanar arm, Technics SP-10MkIII with 12" Triplanar arm. I've heard a much longer list that I don't like and even longer than that are the ones I've simply not heard.
I know, I know, you don't agree aloud that vinyl is inferior to tape medium. Theoretically, maybe not but in reality..
In addition to a solid plinth a robust drive seems to be really important to prevent shimmer in the soundstage. That is why the Lenco, Garrard 301s and some of the early Thorens have a following.
Regarding the tape/LP thing... Direct to Disc is really the only way for vinyl to really show off what it can do. So practically speaking, a tape with good proven provenance is likely to sound better... So in practice on this point I think we are in agreement. I mentioned that provenance thing because it appears that there are a lot of tapes out there that are questionable- its a bit of the Old Wild West on ebay for that stuff right now!
