Integrated amplifiers have definitely found their place in the audio world. With some compelling advantages—space-efficient size, straightforward connectivity, fewer cable requirements, performance levels equivalent to those from separate pre- and power amplifiers—the music lover can now build a cost-effective and convenient music system. Consequently, many manufacturers are putting their best efforts into the design of these components. The A-9155 integrated amplifier is a superb example of audio design focused on user requirements. Based around discrete output stage circuitry, a well-regulated power supply and robust build quality, the core engineering is in place for a finely balanced music system. Incorporating up to five audio components—such as a CD player, a tuner and a turntable through phono-equalizer circuitry, and an iPod through an external dock—the A-9155 is an excellent choice for those wanting something more from home audio.
