is there a market?

Arguably the closest to this sort of thing these days are folks like Yarlung who are recording and issuing on analog tape, selling at $200 per reel 

folkfreak- Yarlung was one of the labels I was thinking of in my previous post-they also do vinyl releases- none appear to be full orchestras, but more small scale stuff, though some classical, e.g. Janaki String Trio. I had heard the tape courtesy of Myles Astor and bought the record because it was interesting. 
It's been a long while, but Lyrita did a great job some years ago with a 20th Century British classical catalog. The classical market has probably narrowed since then. But it was a nice change from some of the usual warhorses.  That catalog was far more than just the Malcolm Arnold record that HP touted. They were well made records (Decca or Nimbus pressed as I recall). 

Actually the Sasha Cooke "If You Love for Beauty" is with a full orchestra, in this case the orchestra from the Colburn Conservatory which is one way of getting quality players at a reasonable price I presume

I live in Chicago, and I do get the chance to tape a few jazz trios on occasion, but no one who has a record deal will allow that anymore.  I love your idea, and I'd be "all in" if one could make it work.  Stereophile has made some pretty good analog recordings over the years, as has record label ECM.  Sears sound recording in New York is another studio/label that does them right.  It is very frustrating to hear so much quality music being "compressed to death" in the recording process.  Most all of the classical music that I listen too are on Lp's pre 1966 for this very reason.  The dynamic range that these old jazz and classical records have is simply incredible. 

Great post, wonderful idea!

It just seems like this might be the right time to do something like this.  I see turntables everywhere, even on commercials.  Maybe part of the problem with digital recordings of orchestras is that there is something emotionally missing from the sound.  The great orchestras should be very much open to anything that would promote them positively.  I just was on the Decca website.  They are reissuing the living presence recordings AGAIN.  Why?  Why not make recordings that are just as good, maybe even better, and allow the the orchestras of today to be appreciated as they should sound.  Decca above all others knows how good all analog records are.
