Hey Jeff, I believe the Marantz 550's last year was 2000 (educated guess) I was using an adcom gd-d1. It is crystal clear but did'nt give me any options with bass, treble, and there were only digital inputs. So I could'nt get pro-logic on my satalite. The real selling point was the $400 canadian (tax included) with the RC-2000mkII. The remote alone was $250 US. I works great. I am happy with my system for now. I am in the process of building a new house. I have had this system or variations in an apartment for 4 yrs. Like having a Ferrari with only first gear. Can't wait for the VOLUME.
