Analogue Productions Jazz, Blues and Classical 33RPM vs 45RPM advice needed!!!


Hi, I know there’s been much discussion on whether the sonic improvement of 45RPM pressings warrant their added inconvenience over their 33RPM counterparts. I understand that this boils down to personal preference. With that said, I need some BUYING ADVICE! I’m about to invest several thousand dollars in purchasing most of the iconic jazz and classical Analogue Productions QRP and Music Matter reissues while they are still available. Sonics being equal or very close to equal, I’d purchase the 33RPM version for their added convenience. However, I understand that this is rarely the case, and for those albums where the 45RPM pressings are noticeably sonically better, I plan to purchase the 45RPM pressings. With that said, for those listeners on the forum who own both 33RPM and 45RPM versions of the same AP album (or if not “own” have gleaned from others), are there specific AP reissues where the sonic improvement of the 45RPM version is so subtle that you often find yourself only playing the 33RPM version? Any input from forum members would be greatly appreciated before I place my order!

Thanks so much,

I have a couple of 45 rpm versions of the same masterings that I own on 33 rpm. They are both worth owning. But you should only buy 45 rpm pressings that you have hear at their best and with your utmost attention. Personally if both are versions are available, get the 33 rpm version first. If you absolutely love, spring for the 45 rpm version. This was a nice thing about about Classic Records. They released a 45 rpm version after the 33 rpm version. Today you don't often get that choice. It often goes the other way. As an example I'll put forth Fleetwood Mac's Rumours. I probably would have bought the 33 rpm mastering. But the 45 rpm was released first. I have no desire to go backwards for this album. I all ready own multiple version of this album. I don't want another copy.
I purchased the Band Music From Big Pink 45 rpm version and found sonic improvements on some songs but not all.
I agree with most of the comments, I own about half of the Verve 45rpm reissues (there is not a 33rpm counterpart to these reissues) and can say that these are easily some of the finest pieces of vinyl on the planet. Stunningly great and worth every penny of the $50 price. Getz/Gilberto, the Billy Holidays, and Ben Webster's Soulville are standouts, even though everyone I have is incredible.
But with that being said, my preference is the 33rpm 200gram reissues. I have kinda found it doesn't matter which one, they are all so friggin great just get them all if you have the means.
Some standouts, Kenny Dorham - Quiet Kenny, staggeringly great, Miles - Someday My Prince Will Come, unbelievable, Son House - Legendary Son House is so unbelievably great it is haunting, Muddy Waters- Folk Singer, Pet Sounds, Brubeck Time Out is perfect, I could go on and on. I don't own the 45rpm version of Time Out to compare but I feel zero need to as the 33 is so damn good. 
Highly encourage you get the Verve reissues as quickly as possible as some are no longer available from AP and are commanding a premium but many can still be had on their website and sometimes they do 15% off, which is even better. There are 25 of them in the reissue collection. 
But I don't think you can go badly on any of the 200gram 33s.
My two cents,
