NAC 552

NAC 552’s distinctive two-box configuration marks it out from the competition just as surely as its unfettered musicality reflects Naim’s core values. The sound-critical electronics of the NAC 552 are mounted on a brass sub-chassis, which is fully suspended on coil springs at a frequency below the threshold of human hearing. This method of suspension maximises isolation, hence minimizing the effect of vibration on the highly sensitive electronic components.  It’s one of the best preamplifiers they’ve ever produced, and by extension, among the best in the world.
