Very nice system. Duplicating is a very safe bet.
If you are going to snow bird somewhere, then you should have a great opportunity to go listen to speakers. You could make this a fun in the sun project.
Speaker sound characteristics are hard to communicate via words or frequency response charts. If you talk about the ultimate output, on one end of the spectrum are highly detailed systems with great slam. These scrape the last ounce of detail from the medium… typically putting the venue and mastering techniques in the spot light (typically solid state). On the other end of the spectrum are highly musical systems that get the gestalt of the venue and the music correctly… ones that emotionally connect you to the music (typically tube)… then everything in between… either well done or poorly done. Then there are particular characteristics of value… like slam, imaging, micro detail, rhythm and pace.
So, where are your values? Your particular musical interests?
