Great system Sarah. Classic in every sense of the word. I can almost imagine what it sounds like. Nice to look at too.
I'm using the vk-5i with my ARC vt100. Amps and preamps come and go, but I always hang onto a set of these. There is a synergy between the bat pre's and arc amps for sure. By the way, your old Terra Set amp is still alive and well in my home office.
That marantz is one of the very best cd's player's I've heard too. You might want to give an audio aero a try someday - if you are looking for even more tube sound from your cd's.
Outstanding system !
