My dealer offers to me the following components for a basic stereo equipment:
amp NAD C320BEE (or C352), CD player NAD 521BEE and tuner NAD 422. For them , speakers Sonus Faber Concertino or Dynaudio 52. My room is 4x7 m, and I usually listen classic and folk/sisties and seventies music. The doubts are related to the speakers: I don't like generous basses and special effects, but natural sound (this a reason I prefer stereo than HT). Can you give your opinion on Sonus Faber Concertino (marketed since 1996, maybe old technology) vs Dyn 52 (or also Dyn 42, Monitor Audio Bronze B2 or Quad 11L).
A money consideration: Dyn 52 or Concertino represent 50% of the total investment (more if we exclude the tuner). Is this reasonable?
NAD makes fine electronics, so there is no issue. Of the speaker choices you listed, I think in terms of pure sound quality with the NAD, and the most for your money, is the Dynaudio 42's. Good luck.
