About the Products A318B
The Almarro A318B is a stereo integrated amplifier designed and hand-made in Japan, featuring a single-ended triode (SET) design with 6C33C-B output tubes, 6SL7 and 6SN7 input and driver tubes. It delivers 18 watts per channel into 8 ohms, with a frequency response from 20Hz to 20kHz (extended to 30kHz in some reports). The amplifier is known for its rich midrange, clarity, and emotional musical engagement, combining the refinement of SET amps with the bass control and drive approaching that of transistor amplifiers. It uses large output transformers and a modest 5.4dB global feedback to improve bass control and frequency extension. The amp includes three RCA line-level inputs, 4 and 8 ohm speaker taps, and is finished with solid wood panels. It weighs approximately 18 kg and measures 370 x 280 x 200 mm. The A318B requires manual bias adjustment and features a relay-controlled timer for tube warm-up. It is praised for its tonal beauty, holographic presence, and high resolution without being overly analytical. The 6C33C tubes used are known for high current capability and low internal impedance, contributing to the amplifier's strong bass performance. The amplifier consumes about 240 watts of power and has a low total harmonic distortion of 0.75%. Although no longer in production, it remains a classic highly regarded by audiophiles for its unique sound signature and build quality.
