Help I am in need of Expertise

Hello there Audiogoners, I am in need of some expertise. I will soon be purchasing a Reel-to-Reel in order to transfer and archive some of my LPs. I typically listen to vinyl and will continue to do so. I am using a Counterpoint SA-9 for this purpose so this will not come into play. My line stage is the Counterpoint SA-11. My question is what FEATURES or SPECIFICATIONS should I be looking for in the "tape source" section of a LINE STAGE? I know what questions to ask, lets say, if I were to be installing a DIGITAL source but what about an analog source reel-to-reel? Would my "older" SA-11 suffice just fine? Any help would be very much appreciated as I enter this "unknown" territory.
