I think a Cambridge Audio is all you need (not sure the NAD does moving coil?) - next step up in terms of quality (IMO) is the Dino, which is wasted in the context of your current system, to my mind.
An advantage of the Cambridge is that if you find you want to upgrade at a later date, you'll only lose 10 or 20 quid on resale, at current s/h value.
And the blue light is great.
