Naim currently provide three power supplies for use with our preamplifiers and active crossover units, the Flat-Cap 2, Hi-Cap and Super-Cap. They can also be used to power the Prefix phono preamplifier.

Some of our power amplifiers have built-in regulated supplies, which can be used to power preamplifiers - other than the NAC 552 - quite adequately, but use of Naim's separate low noise units brings improved musical performance to the whole system. Their independent cases ensure correct earthing and hum-free operation, with large toroidal transformers and smoothing capacitors providing the audio circuits with much greater control and transient capability.

Improvements in the system's sound quality go to the very heart of the music, opening its vocabulary even further, enabling us to enjoy, understand and respond to it much more readily. Inclusion of a Naim power supply offers the additional benefit of allowing the preamplifier to be left switched on constantly, independently of the power amplifier, keeping the unit's complex circuitry fully stabilised at all times.
