Amansker, the SACDs became a limited edition by default when Sony decided to stop supporting the SACD format for popular releases. Instantly after announcing the cessation of the SACD Stones titles, the price of the SACD's tripled on Ebay and at other outlets for used cd's. I don't think the improvement in sound is worth the current price premium for the SACDs. Like Shadorne said, the Stones favored a really rough sounding mix. I own or have heard almost all of the SACD remasters and still prefer to listen to my better sounding vinyl pressings.
