I wonder how many opinions are expressed by people who really aren't very familiar with the performance. Most serious Naim enthusiasts are after music, not watts, and appreciate many qualitative aspects of the whole line. And yes, it doesn't come cheaply. There is extra value for money in a properly set up Naim systems using all Naim gear. There is a great deal of AUDIBLE synergy.
The best advice regarding Naim gear is to listen and if you feel it's worth it, then it is!
