Marantz 17 series, especially the K.I. units. Your experience or knowledge.

Do any of you AudiogoN members have or have had experience with the Marantz 17 K.I. series integrated, CD player and Tuner?

As I have mentioned in other posts I am doing the reading/thinking/talking 

process of learning about some potential good used gear to consider 

for this 2nd system.  Thanks for sharing, Jim
