As a former owner of an NAD 4155, I can tell you that both the reception and especially the sound are bettered by my current AudioLab 8000T (out of production, but I think this basic, "A"-rated unit is now being produced in an updated version by AL's successor TAG-McLaren, although I don't know if it's being imported). Of course the Magnum-Dynalabs are highly regarded, but I wanted AM and presets. But with any decent tuner, the issue of reception is most dependent on the antenna used, and particularly its location, with outdoor-mounted being preferred.
