Naim integrateds are not very good. True Naim quality starts from 282/250DR in my book. If you want to go integrated, look at other alternatives such as Accuphase, Luxman, Pass Labs etc.
The Accuphase E-5000 and Naim 282/250DR would sound quite different. GENERALLY, Accuphase is more to refined, warm and glowing midrange and treble. Naim is more to pace, rhythm and dynamics. Nothing beats a home demo in your room, with your speakers.
