So, when you posted your first response, you looked on thankful's system page, saw he had an Odyssey Audio Candela preamp, had intimate knowledge of the Odyssey Audio Candela preamp and knew for a fact that it did not have a 'direct input' RCA input? And possessing that knowledge infers that you knew some preamps came with that feature, the Candela not being one of them. I'm thinking you did not. I think the first you heard of it was when bdp24 mentioned it. And you gave your abrasive answer not having a clue of these facts. So you were right for the wrong reason.
But, take your tiny victories anywhere you can.
They're so few and far between.
