Any Audiophile recording of The Planets?

I'm not knowledgeable enough about classical to have my opinion taken as anything more than that, but I'll throw in here that my favorite among the versions I own, for both sound and performance, is Boult with the Vienna State Opera Orchestra and Vienna Academy Chorus on Westminster Natural Balance stereo LP [WST 14067], though I don't know what year this was recorded, seems like probably early 60's.

I should mention that I have two pressings of the Boult/Vienna, which don't sound equivalent. Both are black labels, but on the one I prefer has "Westminster" in an ellipse above "Stereo" within a blue bar and "Subsidiary of Am-Par Record Co." at the bottom. The one that sounds inferior to me has the Westminster "Big Ben" logo at the top, "Natural Balance" on the sides and "Stereo" in a red field at the bottom with no Am-Par mention. I don't know for sure which pressing is earlier, but the one I don't like as well does have a date in the dead wax: 7/17/59. (It also has the rear panel of the jacket glued on upside-down, though the jackets are otherwise identical.) Could this be a case of a later pressing sounding better? Photos of the labels can be seen on this page, in the ninth and eleventh positions down (don't bother enlisting Google to translate this from Korean unless you have the time to be amused by the resulting gibberish). DG rereleased this recording on CD in their Westminster series, but it's already OOP. Maybe that could sound best of all, because neither of these records seem like they're top-quality pressings or vinyl, though I very much enjoy the sound of the 'blue-bar' version. At least it's cheap if you find it.

Mre2007: I don't buy new classical releases on CD, just some of the vintage vinyl that I find. As I said, I'm not primarily a classical listener or knowledgeable in the field, and combined with the amount of classical material I inherited from my father, I hardly even do that anymore.
