The NAP 250 is an accomplished stereo power amplifier from Naim Audio, part of the storied NAP lineage, built with a substantial input impedance. The NAP 250 brings Naim's most storied engineering heritage to dedicated stereo power amplification.
Key specs that matter
Input impedance is 47,000 ohms balanced or 34,000 ohms single-ended. Output power is 2 x 100W into 8 ohms. Total harmonic distortion plus noise at two-thirds full power into 8 ohms at 1kHz is 0.013%. Damping factor is 36. At 317.5 x 91.5 x 432mm and 16.8kg, the NAP 250 maintains a manageable power amplifier chassis reflecting Naim's most storied British engineering heritage.
Sound and use context
Expect the musically engaging, rhythmically precise character Naim's broader storied catalogue is celebrated for, with the 2 x 100W output providing capable dynamic performance.
Pairing
Naim's own preamplifier catalogue, including the NAC 332 and NSC 222, offers natural, brand-coherent pairings for a coherently voiced, entirely Naim-based system.
Alternatives
Naim's own NAP 350 offers a considerably more powerful alternative within the same broader NAP catalogue.
