Naim NAP 160 Power Amplifier

The purpose of an audio amplifier is to drive loudspeakers without loss of musical information. In our view many commonly accepted parameters have little to do with loss of information and in some instances, such as the pursuit of large bandwidths or low distortion, unqualified acceptance of them can actually lead to the creation of mechanisms that cause loss of information. Dynamic output impedance, open loop bandwidth, slew rate, propagation delay and stability margins are only some of the many other factors to which we attach importance, and which must all be brought into positive balance.
To this end our amplifiers not only achieve low harmonic distortion, low noise and wide power bandwidth, but also have a constant dynamic output impedance over the whole audio bandwidth. They are able to drive reactive loads without any appreciable change in distortion and are not sensitive to the absolute impedance of the load.
The frequency response of our amplifiers at the bass end is dependent on the gain decoupling capacitor, and the half power bandwidth extends to below 5 Hz. At the top end the response is controlled by a passive single pole filter and is 3 dB down at 40 kHz. The amplifiers do not slew rate limit within this frequency bandwidth.
The amplifiers will tolerate any load from 0 ohms to infinity without damage or instability, the output stages being protected by circuitry that measures the power dissipated. Prolonged running conditions of high dissipation will cause the amplifier to become quite warm and should the case temperature exceed 70° C the mains supply will be interrupted until the amplifier has cooled down.
The cases of the power amplifiers are similar and are constructed of heavy aluminium extrusion which acts as the heatsink. All connections are on the rear. All the amplifiers have large toroidal mains transformers, these and all the other components are secured firmly to an inner chassis.
The NAP 160 has dual rectification, and each channel has its own pair of smoothing capacitors. The NAP 160 and NAP 110 have a built-in 24v regulated supply to power Naim Audio preamplifiers.
High quality components have been used throughout, with great attention to detail construction. Enclosed cermet presets and tantalum capacitors are mounted on epoxy glass printed circuit boards.

Shipping Rates

We calculate your shipping rate based on the total weight of your items and your delivery address. Standard shipping to the UK Mainland (excludes Northern Ireland, Isle of Man, Channel Islands) is free, except where specifically indicated. Don't worry, you'll always see the final shipping charge displayed before you reach the payment step (on the checkout page).

Carriers

We despatch the bulk of our UK mainland items on a 24 hour service.  Non-Mainland locations – Isle of Man, Isle of Wight, the Scilly Isles, the Scottish highlands and Islands, the Channel Islands and Northern Ireland may take a day or so longer. Smaller items are delivered using Royal Mail 24 or special delivery. Larger items are delivered using a courier service such as UPS and occasionally by a Pallet service.

Order Tracking

If a tracking # is provided by the carrier, we will update your order with the tracking information. Please note that some orders will not have tracking numbers.
