Onkyo Unveils Entry-Level Integrated Stereo Amplifier

Onkyo USA has unveiled its A-9150 Integrated Stereo Amplifier.

Onkyo USA has unveiled its A-9150 Integrated Stereo Amplifier.

Backed by 70 years’ experience in hi-fi component design, the A-9150 amp features a customized high-current transformer; two large, custom-made filter capacitors; and discrete output-stage transistors that deliver full-spectrum dynamics and speaker control at 60 W 60 W (4 Ohms, 20Hz-20kHz, 0.08 percent THD, 2 Channels Driven, FTC). The unit is available for an MSRP of $599 USD ($899.99 CAD).

Onkyo’s Discrete SpectraModule generates 500 volts per microsecond slew rate for flat linearity up to megahertz bandwidth. Full-bandwidth signals are served to the power amp to express musical nuance, while the high slew rate significantly improves instrument definition and placement across the soundstage.

The gold-plated MM/MC phono input is backed by an independent phono circuit board featuring dedicated MM and MC equalizers and custom head amp, which operates in discrete configuration for MC signals.

AKM’s 768 kHz/32-bit AK4452 digital-to-analog converter is enhanced by Onkyo’s original DIDRC Filter technology. Developed for the company’s flagship stereo components DIDRC Filter completely removes ultra-high-frequency noise from the signal, which Onkyo claims results in better performance. Despite being beyond the range of hearing, this noise can alter the character of audible sound.

The A-9150 is equipped with four gold-plated RCA line inputs; two gold-plated coaxial digital inputs; two optical digital inputs, and gold-plated speaker posts with A/B selector for switching between pairs of connected speakers.
