Onkyo A-9110 Stereo Amplifier Breakdown and Review

The Onkyo A-9110 is famed for its high quality at a competitive price. The sound quality is comparable to other more sophisticated stereo amplifiers. The sound is solid and remains constant under complex impedance features. The amp is very quiet even when no source connection. It’s impossible to hear any noise from the amp.

The aesthetics of this amplifier are impressive. Its design is a simple black rectangular box with a huge volume knob in the middle. The tone controls and the direct mode give the user the freedom to create different sound profiles that can be switched remotely.

The price is a great deal. It retails at the cost of its predecessor the A-9010 model three years ago. This is a great deal for a low-budget customer. Some people argue that cheap is expensive, but this does not apply to this particular product. It’s a budget technology device that does not lower its quality for cost.

The power output is 30/8 w/ohm. The amplifier can power speakers at an impeccable level. The device comes with a two-year manufacturer’s warranty. This gives one security and faith in the product. The pros and cons include:

  • Jack connectivity for a product of its pricing
  • A clear and distinct sound
  • Affordable without compromise on quality
  • Two-year manufacturer’s warranty
  • Great phono input
  • Four-line input adequacy
  • Simple set-up
  • Lacks a variety of colors
  • Power code is fixed
  • Lacks DAC

Features for the Onkyo A-9110 Stereo Amplifier

The Onkyo A-9110 stereo amplifier has been modified from its predecessor model to include circuitry that significantly reduces sound distortion and increases power output.

Design and Build

The stereo displays a compact look with a thick aluminum front panel. The Tone control knobs are categorized into low and medium frequency balances. The volume knob sits at the center of the amplifier. A phase-matching bass boost is in place to regulate low sound without distortion. On the right corner is a ¼ inch headphone jack. On the rear side, a 1/8” jack is installed for connecting cd-players or tuners. The 30/8 watts/ohm power output is a guarantee of high-quality sound. The amplifier comes with a long, slender remote control with settings for input, volume, phase matching bass, muting, and direct mode.


The Onkyo A-9110’s phase matching boost is an upgrade from the traditional contour circuits that distort and blur sounds in mid and high frequencies. The phase-matching bass boost has received lots of praise from users. The sound is clearer and well-defined as there is no phase shift in bandwidth. The direct mode is a true gift. It bypasses the Bass tunings and allows the signal to pass through without any alteration. Some people might frown due to the 30/8 watts/ohms, but there is a 99% chance that you will not need to turn power to above 30%. The stereo amplifier can push power just fine.


The connectivity is straightforward. It is as easy as connecting the source components, followed by the speakers, and finally the wall plug. After everything is powered up, the amplifier prompts for two settings. There is a mandatory setting for the impedance of the speakers that you are using. This part is as simple as pressing the set-up option on the remote control. The prompt is to optimize performance. The four-line input comes to play at this point. If the display shows only lines one and two, the amplifier is optimized for 4-ohm speakers. If all four lines are displayed, the stereo amplifier is optimized for 8-ohm speakers.

The optional set-up is for the output settings. This option is remote-controlled. If lines one and two are displayed, it displays that your subwoofer is in its default settings. If lines 1-3 are all displayed, this means that the subwoofer is fully active. The display of all four lines shows that the subwoofer is deactivated.

Who is this product best suited for?

The Onkyo A -9110 is best suited for someone who is looking for great sound on a budget. This amp is designed for a low-budget sound. The manufacturer’s intention with this product seems to display the company’s passion for high quality without always concentrating on profits. If you have speakers between 4-16 ohms, then you do not need to break the bank.

This product will suit your needs and save you lots of money. At a retail price of $320 for a product that offers high-quality sound, this is the product for budget technology. It is ideal for mid and high-frequency responses. It is suitable for cars and home use.

According to Andrew Gibbons, playing the guitar is fun but it will take a few months before you can come up with a creative expression. Gibbons is a guitar instructor and has been teaching University music programs for over a decade, when it comes to playing the guitar a lot of factors come into play that determines the type of sounds produced. The guitarist must consider the guitar's neck and body shape, weight, and string type, the amp is also a primary determinant of the sounds produced and that is why Gibbons has created extensive excerpts detailing on the delicate topic. Guitarists must also pick a pose, be it the pro, wizard, hipster, or the old master.
