175 watts per channel through two separate monoblock power amplifiers
Naim NAP 350 takes the 300 Series to monoblock amplification, delivering 175 W into 8 ohms per channel with a balanced XLR input.
The pair of Naim NAP 350 amplifiers contains two monoblocks, one dedicated to the left channel and the other to the right. It is the power-amplifier configuration intended to complete NSS 333 and NAC 332 in the 300 Series, differing from NAP 250 through both higher output and complete physical separation of the two channels.
Key features
- Pure Class-AB monoblock amplification with one chassis per channel
- 175 W into 8 ohms and 345 W into 4 ohms from each NAP 350
- Quoted peak capability up to 1.7 kW for loudspeaker impedance dips
- High-current output stage using matched pairs of Statement-derived NA009 power transistors
- Fully regulated DR power supply
- True Balanced XLR input with single-ended connection possible through a legacy adapter lead
- Optical System Automation with compatible New Classic components
- Power-Line Lite and XLR-XLR cable supplied with each amplifier
NAP 350 or NAP 250
NAP 250 is a 100 W-per-channel stereo amplifier in one chassis and is the direct partner for NSC 222 in the 200 Series. A pair of NAP 350s raises output to 175 W per channel, separates both amplifiers completely and is designed around the NSS 333 plus NAC 332 combination.
One amplifier for each loudspeaker
The monophonic layout avoids sharing power-supply and amplifier circuitry between left and right channels: each chassis receives its own XLR signal and drives one loudspeaker. The physical system layout therefore becomes equally clear, with one NAP 350 associated with each side of the installation.
Compatibility beyond the 300 Series
The balanced input also allows NAP 350 to work with non-Naim preamplifiers offering suitable outputs. Specific adapter cables support earlier Naim generations, while NAC 332 connects directly and can synchronise system control through the optical automation link. The pair configuration reflects that architecture directly: both chassis are intended to work together as a stereo power stage built from two monoblocks. That arrangement also makes channel assignment and cable routing unambiguous in a full 300 Series installation.
