I recently purchased stereo components that make production of a CD important. So I was very happy to find your Records 2 Die 4 articles. I own about 30 on the list and all sound spectacular on my new system. I purchased 5 more from Amazon.com. Ricki Lee Jones Naked Songs sounds tinny enough that I won't listen to it again. Pink Floyd's DSM is nothing special nor is Joni Mitchell's Shadows and Light. For me to be 30 out of 30 in CDs purchased elsewhere and 2 for 5 out of Amazon purchases, my guess is that Amazon presses their own CDs and are of inferior quality. I would like to find a way to verify this. Help.
