Keep in mind I haven't heard the CM10 so what follows is a bit of a guess.
Considering:
- the new power amp is a Rotel RB1090, which is better than the RB1080 I had yet probably not in a different league,
- the RB1080 plus 804S sounded harsh to me (which you may or may not share),
- the old CM4 and RB1080 didn't bother me,
- you don't want to be spending more money in the coming months
I'm inclined to suggest you drop the 804S off your list. It's a bit counterintuitive suggesting this as I tend to think priority should be placed on better speakers. But this can also lead to insatisfaction with the rest of the chain. That would be your judgement call.
As for CM10 vs. 804N, I can't really offer much insight as I haven't heard either one.
What kind of music do you listen to?
What source/s do you use?
Don't rush it. Well, at least to me the learning involved in each upgrade has been part of the enjoyment.
