The spicas are wonderful speakers but do need to be away from the rear wall to image best. IF you find a pair on Audiogon (or elsewhere) for a reasonable price I would get them and see how you like them ... worst case is that you lose the shipping since they're really easy to sell on. I have not heard (nor heard of) the RT3s so I cannot comment on relative performance. Hopefully another poster will fill in this information.
Since your main system is ESLs I find it hard to believe that you would not like the spicas if you have the room to keep them away from the rear wall by a couple of feet. SUre they're not ESLs but I think the design goals were similar ... imaging and midrange rather than bass and SPL.
