Monitor 60s vs 5b with sub

I am looking for a bigger image. I have had my 5bs since the 80s. I am running two subs so low end is not an issue. Do the monitor 60s have a similar sound and will they sound bigger or am I better off with something else vintage? I use them for music in a fairly small and mainly listen at less than 10 feet never more than 20. There is a pair of monitor 60s on Craig's list for $100. Thanks for your input.
