As a Marantz fanboy, I have to pile on. I went through a series of Marantz cd players, starting with the CD5004, then upgrading to the SA-8004, then an SA-14s1 and finally landing on the SA-11s3. This unit is from their Reference line with a copper cladded case, balanced inputs and a built in DAC. No question there were meaningful sonic improvements moving to the 11s3. I actually own two, both bought gently used and paid around $1,800 each. They come up occasionally for sale but seem to go quickly.
