Best pressing of Tchaikovsky's Violin Concerto?

I certainly wouldn't start with Van Cliburn, as that's the piano concerto!  I'll look through my collection to see if there's any other recording on vinyl that I like as much as the RCA Heifetz..

I do like the Heifetz and the Kogan, and the reissues of those recordings are really quite good.  I always liked Perlman's version that I had on a Chesky CD reissue, that must have been a Reader's Digest release on vinyl, might be worth looking for.  The engineering for that recording is top-notch, though the pressing quality might not be so great.  I also note there is a DG vinyl reissue with Anne-Sophie Mutter, I have always admired her work but have no idea of this performance or the quality of the recording (as a rule, I'm not a big DG fan from that era). 

That Mutter/Karajan performance is now available on vinyl as well.

Well, remember that RCA was selling Heifetz more than the orchestra at the time, so they were a little guilty of spotlighting him, hence the "diminished" orchestra, IMHO.
