About the 9130

The Hafler 9130 is a stereo power amplifier designed for high fidelity audio performance. It delivers 65 watts per channel into 8 ohms with a frequency response of 20Hz to 20kHz and a very low total harmonic distortion of 0.008%. The amplifier features a damping factor of 50, input sensitivity of 1.1V, and a signal-to-noise ratio of 100dB. It is built with high-quality passive components including polypropylene film capacitors and 1% metal film resistors, contributing to its superior sound quality. The 9130 includes volume controls on the front panel, a soft turn on/off circuit, thermal protection, and a voltage selector switch for 110 or 220 volts AC. It can be bridged to provide 150 watts mono into 8 ohms and can drive 4 ohm loads reliably. The amplifier measures approximately 432 x 228 x 89 mm and weighs about 9 kg. It is praised for its refined, clean sound that is well suited for small ensembles and efficient speakers, providing a 'you are there' listening experience. Originally released around 1991, it remains a highly regarded amplifier in the mid-fi price range with a reputation for durability and ease of servicing.
