The SAC Igel 60 is a mono power amplifier that represents a blend of compact design and robust performance characteristics. With dimensions measuring 170 x 82 x 205 mm and a weight of 4.5 kg, it is designed to efficiently manage heat and deliver power without imposing significant space requirements. In terms of output power, the Igel 60 can deliver 80 watts into 8 ohms, 120 watts into 4 ohms, and 150 watts into 2 ohms. The input is facilitated through a single RCA connection, while the output features speaker terminals capable of accommodating banana plugs. The amplifier operates using a Class A/B push-pull configuration, exclusively utilizing bipolar transistors across its output stages. The control circuitry is noted for its significant negative feedback, reported at levels between 80 to 100 dB, facilitating reduced distortion and improved output impedance, thereby enhancing speaker control with a damping factor purportedly around 8000. Other technical features include protection circuits for over-temperature and DC detection, ensuring longevity and reliability during operation. Notably, the Igel 60 shares design aesthetics with SAC's other components, maintaining a utilitarian yet stylish appearance that has remained unchanged for decades. Performance-wise, the amplifier is characterized by firm and well-articulated bass, with a slight inclination towards upper midrange emphasis, which can impact tonal balance, offering a lively and engaging sound signature.
