I've owned a couple different SACD players since 2001, and my advice is somethibng like Ghasley's: don't just buy something because it's available in the SACD format because more often than not you will find that there is not enough of a POSITIVE difference between the current remaster and something you already have. Over the past 5 years, I have purchased about 325 SACDs, but kept less than half of them.
My sincere apologies to the person who suggested DSOTM, but in all candor this is one of the poorest remasters in the format I have heard so far.
On a positive note, I believe that either of the two Showcase samplers from Opus 3 or the Red Rose sampler are about as good as you will ever hear music in the SACD format.
