The Supreme Pluses add more "punch and snap" and are better suited for Jazz.
The RS1s add more "realism and clarity" and are better suited for classical/full scale orchestra.
I really enjoy the piano/string notes coming out of the Supreme Pluses on a small scale like duos, trios, and quartets but it gets a little congested with a full scale orchestra ensemble.
Keep in mind that both are rear ported so you would have to see if they would work in your room.
Good luck.
