Building on acclaim for the award-winning A-9010, Onkyo again raises the bar for musicality in the entry class with its A-9150 Integrated Stereo Amplifier. Unique technologies coalesce around a refined amplification system to deliver outstanding transient response, superb dynamics, lifelike soundstaging, and nuanced articulation of your favorite analog or digital music. Key to this sense of realism is Discrete SpectraModule™, which boasts a slew rate of more than 500 V/µs for flat linearity up to megahertz bandwidth. Rediscover the vitality of analog with MM/MC phono input served by dedicated equalizers on a separate circuit board, with custom head-amp operating in discrete configuration for MC signals. Listeners with big CD libraries will discover new life in the format with AKM's premium 768 kHz/32-bit DAC (AK4452) enhanced by DIDRC Filter, an original circuit technology that cleanses signals of high-frequency noise. Backed by 70 years' experience in hi-fi design, the A-9150 invites you inside the energy of every musical performance.
