Naim Audio amplification
Naim Audio is a specialist British manufacturer of high-end audio amplifiers well known for their signature qualities of ""pace, rhythm and timing"". The company is equally known for its uncompromising and idiosyncratic approach to hi-fi design, insisting that specifications and test bench power ratings are poor indicators of how good an amplifier sounds.Naim's approach is characterised by the absence of tone controls, the use of the DIN connectors instead of the RCA connector used almost ubiquitously in the home audio equipment industry, and reliance on over-engineered external power supply units (PSU) to deliver current for musical transients.The company's two-channel NAP 250 amplifier that made its début in 1975 is among Naim Audio's most long-lived and well-known products.
