Comparing pre amps and the upgrade dilema

I presently own a Blue Circle BC 3.1 Galatea. My previous reference was a ARC LS5mkIII. I have been thinking of upgrading to a BC 3000 or a LS25mkII. And have also considered the LS16mkII, That is a downgrade at least with price.
I no longer use balanced and care very little about a remote.
I loved the sound of the LS5mkIII and in hind site should have held on to it. Does the current ARC pre's sound similar?

It is not a straight foward thread. But make what ever sense out of it you can
