The MFSL version goes for the $300 range when it is mint and unopened. Otherwise you can find it on Amazon or eBay for the $40 to $75 range. Keeping an unopened copy just to try to sell for $300 is stupid. Open the damn thing and listen to it or sell it to someone who will (at a price where they can afford to open it).
I have three versions of DSOTM.
CDP 7 46001 2
(Capitol Records 11th issue) according to pinkfloydarchives
The 1992 remaster
MFSL (bought it new at MSRP when it was released)
I have heard the SACD (the SACD 2 channel layer) once at a stereo meet
I have not heard the black triangle version or any of the other early issues that apparently used the same mastering.
Of the three I have, my favorite for headphone listening is the MFSL. It is easy comfortable listening that transports you away. It is very nice on headphones. A smooth sound where all the instrument sounds work together and meld together. Nothing fights over another instrument or sound. Cymbals are a bit toned down. Floor toms have a bit of a bloom. Percussion in general is not tight and is laid back. But the overall sound of the entire CD leaves you enjoying the entire CD with no ear fatigue or brain fatigue. Very easy to just zone out to and enjoy.
The Capitol Records 11th issue that I have is slightly harsh compared to the MFSL. Cymbals are more present, but so is sibilance in the vocals. Floor toms have less bloom, but the percussion is still not very tight. Overall listening doesn't leave me as relaxed or enjoying the music as much as the MFSL version.
The 1992 remaster suffers from compression. It really grates my ears. The percussion is tighter and there is no bloom in the floor toms or any other tom. A more rock style sound. Instrument sounds sound like they are layered on top of each other as very separate sounds rather than combining to compliment each other (I suspect too much compression was used to get more separation). If you're playing DSTOM to a party or to a light show this is the version to use (if you don't have the SACD). I don't like listening to this version on headphones. I only listen to it when I want a rocking version of DSTOM with percussion impact, and then I listen to it on my studio monitors rather than the headphones.
The SACD was a fantastic listen. I didn't notice any effects of compression but the percussion was very tight and the toms sounded like normal toms. I recall some odd mixing choices compared to how I'm used to the MFSL version sounding. Very good sound and more rocking than the MFSL version. I might have to buy it even though I don't currently have an SACD player.
It is well worth having multiple versions of DSOTM. I use the MFSL version when I want to enjoy the music and one of the other versions when I want a more impactful rock style sound.
I'm still curious about how the black triangle version sounds.
