I have the NuForce in a second system, driving modified Klipsch Forte II's. They have the Ti tweeters & mids and modified crossovers. The Fortes can easily sound bright/harsh and have with a couple of ss integrateds. I can assure you, that's NOT the case with the NuForce. I find the NuForce to be smooth & detailed, with great low end control.
Can't comment on the NAD, as I haven't heard it.
