The NAC 152 XS features an additional output in addition to the Naim standard DINs. This stereo output on two RCA sockets, is optimised for connection to an active subwoofer, supports the growing use of 2.1 systems. Its rear panel layout is similar to the NAC 202 and hence is Fraim friendly. The NAC 152 XS can be powered from the preamp power outputs of the NAP 155 XS or NAP 200 or can be upgraded by powering it from either a FlatCap XS or HiCap power supply. One of the DIN inputs can supply power to a Naim StageLine outboard phono stage.

The Naim NAC 202 combines first-class sound quality with flexibility, style and excellent value. Significant improvements in technology led to an entirely new range using new high quality star-earthed circuit boards, combining the classic Naim values of musicality and power with flexibility and value. The Naim NAC 202 may either be powered by a NAP 155 XS or NAP 200 amplifier or significantly upgraded by adding Naim power supplies to independently feed the analogue audio and digital control circuits.

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.
