Super Rare Naim Three Channel Amplifier

Just the piece you need to complete your home theater from one of our absolute favorite audio brands.

UK made. Tons of upgrade paths with external power supplies available for the consummate tweaker. Incredible build quality and attention to detail resulting in a wonderful engaging and detailed sound. Best used with other Naim gear but will work with the rest.

Fully bench tested where it performed to factory specs, as well as sounded fantastic in our listening lab.

In very good condition without any noticeable signs of wear other than an occasional scuff from handling.

Includes the power cable and the manual.

Details:
The Naim NAPV175 is a three channel power amplifier designed to power the front and centre channels or the front and surround channels in a home cinema system.

All home entertainment systems need the best possible amplification if they are to reproduce accurately the original soundtrack with all the dynamics and emotion the composer or director originally recorded. 

Dynamics and emotion are trademarks of the Naim sound: the NAPV 175 three-channel amplifier is the perfect partner for our AV2 processor. 

The power amplifier topology and layout of the NAPV 175 are derived from Naim's flagship amplifier, the NAP 500. The best possible performance is achieved by using extremely fast, high power output transistors. All other components have been selected for ultimate sound quality. 

Each of the three power amplifiers has its own supply consisting of a dedicated transformer winding and selected rectifiers and capacitors.

The component board is joined to the low-resonance, die-cast chassis using vibration-reducing mounting systems.

Low-energy-transfer feet further diminish the effect of microphonic disturbances to the signal.

The circuits and power supplies in the NAPV 175 exactly match those in the NAP 150 allowing the flexibility to specify matching channels of power amplification for any home entertainment system.

Our Testing Process for Amplifiers (Solid State) at SkyFi:

We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage.

We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier then remains powered on to "burn in" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will be also be tested.

Final testing involves pushing actual music thorough the amplifier. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we're very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.
