The CDX must have quite a player. According to my old Audio magazine annual buyer’s guide, it listed for $700 in 1990. From what I can find, even now people are asking close to $300 for them used.
I’d be shocked if the S1000 sounded better. On top of that, it isn’t going to have the cool orange display to match your Z9.
The Z9 is an awesome beast. The only reason I gave mine up is because my wife dragged me into HDMI with Roku, and I figured if that was the route we were going, I had to get an HDMI front end order to hear the programming in true 5.1. But I’m still using the Z9 as a multi-channel amplifier, along with a Yamaha CXA-5000 pre-pro.
