Product Description
Naim NAP 350 power amplifier is a mono design or monobloc and is supplied in pairs, providing plenty of power and presence with precise musical performance. NAP 350 sets a new benchmark in the Naim range at this level and are a perfect match for the NAC 332 pre amplifier along with NSS 333 streamer and/or NVC TT phono stage, or indeed as power amplification with another excellent pre amplifier.
NAP 350 monobloc boasts 175 Watts per channel and can drive any speaker with ease. Dynamics are incredible and inputs are balanced XLR connections for the best possible low noise connection. As with the latest NAP 250 6th gen power amplifier, NAP 350 also features the latest DR power supply. This provides superior regulation and noise performance. The casing matches the other latest models from Naim and is made of anodised aluminium.
High build quality
The power supply in an amplifier is important for performance and noise. Multiple voltages are needed for different sections. Naim has developed a power supply system known as DR or Discreet Regulator. This provides the cleanest and most stable power possible. In addition, the NAP 350 uses the best components in the rest of its circuitry, such as the NA009 transistor for the regulator output, along with low dielectric absorption capacitors. Everything is optimised for the best possible sound quality.
Classic design updated
Naim products have a classic and timeless look as well as a high build quality. They are kept as simple as possible, with no unnecessary adornments. In fact, the NAP 350 has just an input, output and an on/off switch. The case is made from billets of aluminium, which are then sandblasted and anodized, for a long lasting finish.
Low noise Naim DR power supply
Naim has designed their own DR (Discrete Regulator) power supply. These are used in all the current range. The power supply may seem simple but it has a difficult job. It must be stable as well as keep the output voltage clean and consistent. Moreover, there are a number of different voltages required by different sections of the unit. Most cheaper units use fixed voltage regulator IC s for the secondary voltages. These are not ideal as they can be unstable and have a limited current capacity.
Instead, Naim uses discreet components. This gives full control of the design. The transformer is the first component in a power supply. Sometimes two are used, one for each channel is a stereo amplifier. However, Naim uses only a single large transformer. This has a lower impedance than two transformers meaning that the reservoir capacitors charge up faster. Another noise issue is dealt with by the cabling.
XLR balanced connections
The NAP 350 connects to pre amplifier via balanced XLR connection. These are chosen for their low noise connection properties. Normal RCA cables are not balanced and can drag in all kinds of noise, especially with long runs. XLR cables are therefore also an excellent choice if you wish to situate the NAP350 amplifiers next to your speakers and run an XLR cable from your pre amp to these.
XLR plugs and cables have three conductors, a hot or positive wire , a ground and a negative wire. In all types of audio cable, an outer layer of copper is used as a shield, this is usually grounded. However, balanced cable has three conductors. Each of the two active conductors carries the same audio signal but with opposite polarity or phase. This is done by the sending equipment, for example, the preamp. At the amplifier end of the cable, the signal is flipped back to the way it was. When the two signals are recombined any noise from the cable is eliminated.
Naim Audio ethos
The Naim ethos is simplicity. Naim products have no bells and whistles and focus on sound and build quality. The units are hand built using only the best components. Naim began by making active speakers for the fledgling commercial radio sector, of the early 1970s. Consequently, the success of the NAM 502 active speaker led to the forming of Naim in 1973. NAIM stands for Naim Audio Integrated Amplifier. This latest range combines 50 years of experience into making the best possible components possible, an impressive upgrade on the prior Classic range.
