The years of research spent developing the flagship NAC 552 preamplifier introduced a new level of technical and musical performance. Many of these developments, along with its elegant styling have been applied to NAC 282.

The NAC 252 descends from the NAC 52 - still one of the finest preamplfiers ever manufactured. It brings both control and connectivity advances over the NAC 52, and a significantly enhanced construction, aesthetic and finish. Its performance, too, is enhanced with the benefit of a decade of R&D bringing yet more speed, detail, transparency and music.        

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 552 PS is the dedicated external power supply for the NAC 552 preamplifier.
