Naim Nac 552

The NAC 552 is by some distance the most advanced Naim preamplifier ever and has some claim, therefore, to being the best preamplifier, period. The introduction of the NAP 500 in 2000 brought with it a new level of technical and musical performance. A Naim design project group began reviewing the existing preamplifier designs exploring possibilities for major design improvement over the then existing reference preamplifier: the Naim NAC 52.
