The C200 is a wonderful preamp and was rated stereophile class A. The condition of the preamp is very good and I am only rating it a 8/10 because of its age. The units will be double boxed in McIntosh boxes. The C200 is certainly in the class of "potentially the last preamp you ever own." It is that good!
If you are not already familiar with this preamp, you will see from the pictures it is a two box design with a dedicated power supply, making it extremely quiet and very dynamic. Again, the two box solution speaks to the, "potentially the last preamp you will ever own" class that this preamp is in.
