If you don't need the other features, I would buy the Naim. I have heard no other integrated amp at that price point that I like as well as the Nait.
One question. Can you bring your Linn speakers to a dealer and try them with the Naim just to make sure they are a good match? Or try the Naim with your speakers in your home with option to return if for some reason it is a bad match? If you did the former, you could compare your speakers paired with the Nait against other options available at the dealer. Then again, maybe that is a bad idea...($$$)
