Onkyo A-9110 Integrated Stereo Amplifier

Description

A-9110

Integrated Stereo Amplifier

Onkyo builds on the success of its A-9010 pre-main amp with
the new A-9110 Integrated Stereo Amplifier, a component that refines an
original amp design that’s won an excellent critical and commercial reputation
for dynamic, musical sound. Lively dynamics, deep bass, and layered detail
emerge from warm and expressive tuning. WRAT delivers high-current power
stability via large custom capacitors, while low-NFB amps capture the depth and
spatiality of analog and hi-res recordings. Five RCA inputs including MM phono
stage connect your sources while high-quality speaker-posts reveal Onkyo’s
hi-fi heritage and careful attention to detail. The A-9110 invites you into
each album, the hours passing comfortably in pure analog sound.

Stable high-current power with wide-range amplifiers

Dynamic changes in music cause impedance to fluctuate. If
power can’t be delivered when impedance drops, sound quality suffers. Onkyo’s
solution is WRAT, specifically its high-output EI transformer, huge custom-made
main audio capacitors, and carefully selected high-quality parts. High-current
stability controls the speaker-drivers for accurate and assured reproduction of
dynamic musical passages. Further, the A-9110 features Onkyo’s time-proven
low-negative-feedback amplifier topology that distinguishes the timbral warmth,
fullness, and vibrancy of the recording. This circuitry captures a wide
frequency spectrum with uncommonly low distortion.

Sounds clearer at low volumes

When playing music at low volume, the signal normally drops
close to the component’s noise floor. The signal picks up noise, which is
amplified, and the result is muffled sound. To avoid this, the A-9110 features
Optimum Gain Volume Circuitry, a volume circuit that requires less than half
the usual amount of attenuation. The signal never approaches the noise floor,
so you can enjoy clearest sound at low volume.

Phase Matching Bass Boost enriches sound at low volume

Most pre-main amps have a loudness button designed to boost
low-mid frequency sound. However, conventional designs are prone to
phase-shift, which degrades the clarity of the vocal frequency band. Onkyo’s
Phase Matching Bass Boost function eliminates phase-shift between low- and
mid-range frequency bands above 300 Hz. Bass response is enhanced without
compromising vocal clarity, and that’s something especially useful when playing
music at low volume where bass and high-frequency sounds are more difficult to
hear.

Thick and rigid chassis tames resonance

Every hi-fi component generates electromechanical resonance.
This translates into signal noise, and that impacts on the sound coming out of
your speakers. To combat the negative effects of vibration, the A-9110 features
a rigid metal chassis that’s 1.3 times thicker than the A-9010 at 1/16″
(1.6 mm). Working together with large, wide-spaced insulators, unwanted
resonance is virtually eliminated.
