Tccaux,
It's been a while since you've posted, so I don't know where you are in the process, but I'll offer a suggestion. I own the Sanders 10c with two Magtechs (individually driving the transmission line and the 'stat panels). After having been extremely impressed by the Zesto Andros phono stage, I recently acquired a Zesto Leto line stage. I am not exaggerating when I say that it is perhaps the best preamp that I've ever owned. Just offering this as an alternative to your Audio Research possibilities.
If you're ever down towards Houston, feel free to drop in for a listen.
Mike
