Are you sure you're not referring to Pristine Classics "ambient stereo" downloads?
Look, if you don't hear a stereo effect when you listen to the BPO box, fine. Your enjoyment is really all that matters. But I've been specific in my references. I completely respect your choice if that's what matters to you, and if I would consider your review incomplete, as an unpaid devotee, I'm enormously grateful for what you offer. You don't have to read any more. Put all this out of your mind and move on, if you wish.
So be warned the following is about the pleasure of knowledge more than it is of music:
Here's something that is surprising, but just as specific:
In Adobe Audition, you can use the Center Channel Extractor to isolate all frequencies shared by two L-R channels. This "center" channel and the side channels can then be mixed to produce whatever desired proportional result you want. So if you wanted to exclude all stereo content, you could dial the side channels down to zero and bring out whatever true mono exists between left and right. Or you can suppress all the mono material and listen to only the audio in the two channels that is different from each other.
Let's say you do this to DG's wartime Schubert 9, first movement. What do you get? Nearly nothing. The music, while presented in two channels, is very close to true mono. Do this to MOT's transfer of the same for Pristine, what do you get? The same- if anybody juiced the audio , it was applied as a mono effect. Do this to the same performance in the BPO box and you get a complete waveform of stereo sound- ambient effects applied to the music to produce an artificial sense of space.
You might find the stereo effect easiest to spot on the damaged Schubert "Unfinished" second movement, which sounds a might bit synthetic, they've juiced it so much.
