Naim NAP-250
Not much is documented about the Naim NAP-250 beyond early-1980s directory listings and classified ads. It was a power amplifier. An Audio-Collection system suggestion (p.31) puts it at the top of the Linn/Naim chain: a Linn Sondek LP12 turntable, Linn Isobarik loudspeakers, the Naim NAC32 preamplifier, a Linn Ittok arm, and a Koetsu moving-coil cartridge, with the NAP-250 doing the driving.
A 1981 HI-Fi-Stereo-Buyers equipment listing (p.53) is more specific. It rates the NAP-250 at 125 watts continuous per channel, both channels driven into 8 ohms from 20-20,000 Hz, with 0.02% THD and IM distortion. The same listing gives a 5″ H × 17″ W × 12″ D footprint, stepped 2-dB level controls, and a protection indicator. The entry also notes a sibling, the NAP 160, described as similar to the NAP-250 except for its built-in 24-V regulated power supply. That suggests the NAP-250 used a different supply arrangement, though the directory doesn't say what.
The classified pages of the time give a price. A private seller in Audio (November 1981, p.88) asked $1,000 for a NAP-250, or $3,400 for it together with a pair of Linn Isobaric loudspeakers with stands. That is essentially the entire period record in the Archive's files. No full contemporary review has surfaced.
