Click here to read an excellent writeup on the NAP 250 from Audio Affair UK that's definitely worth the read. Here's a snippet:

The Sound

We have had the pleasure of trying out every variation of the 250, and the sound really hasn’t changed. Although, that’s almost certainly because it hasn’t needed to change! When the 250 first appeared, it became an instant classic (and likely blew everyone’s mind in the process). Its delicate yet robust handling of sound became associated with the Naim brand, ultimately becoming what was known as the ‘Naim sound’ that other units bear too.

As I said before, it’s fast, it’s expressive and it’s wonderfully simple and clean. Energetic without being overwhelming, and wonderfully bold and warm. It hasn’t lost what makes it special, and it has remained the apple of many audiophile’s eye ever since.

We have a total of three of these amplifiers at the time of this writing, so please inquire if you need more than one for perhaps an active setup (or second system).

Fully tested and inspected per our process outlined below, and working as it should throughout.

The SkyFi Testing Process for Solid State Amplifiers:
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.
