Yeah Don, it's the initial recording process and the mixing and mastering that's applied to it which determines the quality of a recording, not whether it winds up on CD, DVD-A, or SACD. Other than not having the capacity for multi-channel discrete surround sound(which processing such as DPLII can at least partially substitute for), the CD format has frequency response and dynamic range capability which is more than adequate for human ears and the material which we listen to, despite claims to the contrary in the IAR article.
