Overview

Onkyo A-9150 Integrated Stereo Amplifier 75W

Polished Power Amplification

In order to provide a clear and defined audio image, it's imperative that sounds of different frequencies arrive at the listening position simultaneously. The power amplification circuits utilized in this design feature original topology that's carefully tuned for phase accuracy, wide-spectrum signal reproduction, and natural transient response. Fitted with hand-selected audio-grade parts, the amplifier contributes to lifelike and involving sound quality.

Detailed Audio Reproduction with Discrete SpectraModule™

Discrete SpectraModule boasts a slew rate of over 500 V/?s, significantly higher than any competitive products that use a standard IC chip. High-voltage performance enables flat linearity into the megahertz range for full-bandwidth signal reproduction. This is important for natural transients providing incredible fine detail in music, and for creating a more realistic soundstage.

Dedicated MM/MC Phono Circuit Board

The A-9150 makes your records sound better than ever. A gold-plated phono input supports signals from either MM or MC cartridges fitted to your choice of turntable. The separate phono circuit board features dedicated equalizers served by a top-quality customized head amp, which operates in a discrete configuration for MC signals. Together with analog power amplification, this high-grade phono input design expresses the depth and vitality of music on vinyl.

Customized High-Current Transformer and Custom Audio-Grade Capacitors

Current has great influence on sound quality. High current is required for a better grip on the speaker drivers, improving control and accuracy. A customized high-output transformer and two huge custom capacitors inside the A-9150 deliver current through discrete output-stage transistors that are kept cool by an aluminum heat sink. The speakers react instantly, with excursion precisely controlled for accurate articulation even through dynamic and complex musical passages.

DIDRC Filter and Hi-Grade DAC for Transparent Sound

Distortion in the ultra-high-frequency spectrum can have a noticeable impact on the character of audible sound. Even the best D/A converters introduce some noise to the signal, and that noise is amplified, distorting the sound you hear. A DIDRC Filter completely erases the ultra-high-frequency noise. The performance is optimized for digital music with an undistorted frequency response extending far above the range of audibility. Combined with a premium 768 kHz/32-bit DAC, you can enjoy a greater sense of realism from digital sources, with none of the unnatural "synthesized" feeling sometimes produced by digital processing.

Impressive Build Quality with High-grade Terminals

A peek under the hood of the A-9150 gives you an idea of what to expect. Held in place by a flat chassis that tames resonance, the digital audio board is isolated from the analog circuitry. L/R channels are symmetrical to equalize signal path-lengths and minimize stereo playback errors. Coaxial digital inputs, phono input, speaker posts, and RCA line inputs are gold-plated and of excellent quality. Finished with an aluminum front panel and volume control, the A-9150 proves itself to be a staple component of any high-quality setup.

The A-9150 Integrated Stereo Amplifier reaffirms Onkyo as brand that is on the forefront of delivering natural musicality at a realistic price. The 60 watt x 2 (4 Ohms, 20Hz-20kHz, 0.08% THD, 2 Channels Driven, IEC) integrated amplifier appeals to listeners that enjoy music in any format, vinyl to CDs and other digital media. Backed by 70 years’ of experience in hi-fi component design, the A-9150 benefits from intensive R&D that has delivered the true atmosphere and energy in the musical performance, and resulted in new technology that involves the listener more deeply in music.
