Preamps: Nad c162 vs. ROtel rc 1070

Leaning towards the Nad...anyone have opinions on the ROTel?
I've had both Rotel and NAD gear and I'd say they are comparable; both represent good value. Without taking the covers off the two models in question you really can't judge them. If the amp was NAD then I'd choose the NAD preamp and likewise for the Rotel. So what amp will it be paired with?
