I've owned the CJ17ls and pretty familiar with most ARC gear.
Most people giving you advice aren't really knowledgeable about what they are saying.
Here's the first and PRIMARY questions to ask if you are considering the 17LS:
1. Will you be running long interconnects from it to your amp?
2. What is the input impedance of the amp?
Probably the only downside to the 17LS is that it isn't balanced and can't drive long cable runs to the amp as well as other CJ preamps like the ART. If you're using low capacitance cables and short runs, then the 17LS is a great option. You will be getting essentially the same performance of the legendary ART at a fraction of the price.
As for ARC gear, you can almost NEVER go wrong with them either. It will give you balanced outputs, which could be an advantage.
Both pieces would have more in common than dissimilar as they are true reference level preamps.
BTW, the 17LS has one other quirk that may bother some people. It's resister ladder volume control clicks at each change of volume.
Personally though, I'm wondering why you feel the need to change preamps from the Cary.
