Product Description

Onkyo A-9150 120 Watt Integrated Stereo Amplifier w/ Built-In DAC

Building on acclaim for the award-winning Onkyo A-9010, Onkyo again raises the bar for musicality in the entry class with its Onkyo 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 Onkyo A-9150 invites you inside the energy of every musical performance.

Designed for Enhanced Power Amplification

In order to deliver a clear and comfortable audio image, sounds of different frequencies should arrive at the listening position simultaneously. The power amplification circuits in the Onkyo A-9150 feature topology that’s designed for phase accuracy, wide-spectrum signal reproduction, and natural transient response.

Enhanced Musicality with Discrete SpectraModule

The discrete SpectraModule features a slew rate of over 500 V/μs to help produce accurate definition of instruments ranged around a larger and more realistic soundstage.

Dedicated MM/MC Phono Circuit Board

The A-9150 features a gold-plated phono input that supports signals from either MM or MC cartridges fitted to your choice of turntable. Its separate phono circuit board has dedicated equalizers served by a customized head amp, which operates in discrete configuration for MC signals. Together with analog power amplification, this phono input design helps express the depth and vitality of music on vinyl.

High-Current Transformer and Capacitors

Current influences sound quality; high current is required for a better grip on the speaker transducers, improving control and accuracy. A high-output transformer and two capacitors inside the Onkyo A-9150 deliver current through discrete output-stage transistors that are kept cool by an aluminum heat sink. This allows the speakers to react nearly instantly, with throw-range controlled for accurate articulation, even through dynamic and complex musical passages.

DIDRC Filter and 768 kHz / 32-Bit DAC for Natural Sound

Distortion in the ultra-high-frequency spectrum can have a noticeable impact on the character of audible sound. The DIDRC Filter is designed to completely erase ultra-high-frequency noise. Performance is optimized for digital music with an undistorted frequency response extending above the range of audibility. Combined with a 768 kHz / 32-bit DAC, you can enjoy an enhanced sense of realism from digital sources, with none of the unnatural “synthesized” feeling sometimes produced by digital processing.

Designed for Enhanced Quality with Reduced Resonance

Held in place by a flat chassis designed to tame resonance, the digital audio board is isolated from the analog circuitry. The L/R channels are symmetrical to equalize signal path-lengths and minimize stereo playback errors. The coaxial digital inputs, phono input, speaker posts, and RCA line inputs are gold-plated to prevent corrosion and improve connectivity. The Onkyo A-9150 is finished off with an aluminum front panel and volume control.
