ONKYO A-9110 Integrated Amplifier

Onkyo A-9110 Integrated Stereo Amplifier (Open Box)

An open box Onkyo A-9110. Please note that no factory warranty applies. The A-9110 is Onkyo's refined successor to the well-regarded A-9010, carrying forward the same warm, dynamic character that earned the original its strong critical reputation while introducing meaningful engineering improvements throughout. The Class AB amplifier delivers 50 watts per channel into 4 ohms, powered by Onkyo's WRAT (Wide Range Amplifier Technology) — a high-output EI transformer paired with large custom-made main audio capacitors selected specifically for high-current stability under the fluctuating impedance loads that real speakers present during dynamic musical passages.

The low-negative-feedback amplifier topology is central to the A-9110's musical character, capturing a wide frequency spectrum with low distortion while preserving the timbral warmth and spatial depth of both analog and hi-res recordings. Optimum Gain Volume Circuitry keeps the signal well above the noise floor at lower listening levels, eliminating the muffled quality that plagues conventional volume circuits at modest settings. A Direct Mode bypasses the tone and Phase Matching Bass circuitry entirely for the most transparent signal path, and the signal path itself has been significantly shortened compared to the A-9010 for improved accuracy and transient response. Five RCA analog inputs include a built-in MM phono stage with a discrete op-amp for authentic vinyl playback. Wide-spaced non-magnetic speaker binding posts, a 1.6mm rigid metal chassis for vibration control, and large wide-spaced insulators complete a thoughtfully built package at an accessible price point.
