Besides, the new A-9110 has a chassis that is 1.6mm thicker and rigid. It cuts down on unwanted electromechanical resonance that brings about signal noise that lowers output quality.
Design And Quality
The Onkyo A-9110 is an entry-level integrated amplifier with a well-laid front panel that gives it a costlier look. The master volume dominates the face, with other tone control knobs, a 6.3 mm jack, and direct mode bypass knobs completing the awesome craftsmanship.
The knobs are highly sensitive, and the controls respond well to the remote control. The sturdy old school design comes in a black or silver finish.
The chassis is metallic and thicker than the A-9010 at 1.6mm, coupled with large and wide-spaced insulators to handle the unwanted resonance. There are 5 analog audio inputs and 1 output, with high-quality gold-plated banana plugs.
Furthermore, this amp banks on WRAT technology to solve impedance fluctuations, while the low-NFB express the depth and expanse of analog and hi-res audio files.
Performance
Typically, dynamic music changes fluctuate the impedance, and if the power goes down, the sound quality suffers. Onkyo uses WRAT, with a high output EI transformer and huge capacitors to stabilize power for accurate and certain replication of dynamic audio passages.
The high-quality circuitry with a low-negative-feedback amplifier topology maintains the timbral warmth, fullness, and vibrancy of a recording well separated.
To keep the signal above the components’ noise, Onkyo uses an Optimum Gain Volume Circuitry that requires low attenuation, leaving you a clear and deep sound at low volumes.
Direct Mode bypasses Phase Matching Bass Boost and tone circuitry to use the shortest signal route from source to speakers, keeping the recording as original as possible.
Stand Out Features
A striking feature of the Onkyo A-9110 is its clearer sound at low volumes. Typically, muffled audios result from low volumes due to the audio signal dropping to almost the same level as the component’s noise floor. When this happens, the signal picks up noise which is subsequently amplified.
Following the rule, “Garbage-in, Garbage-out,” amplified noise results in poor quality muffled sound. To sidestep this, the A-9110 utilizes a unique volume circuit—Optimum Gain Volume Circuitry that keeps the signal away from the noise floor. The result is crystal-clear sound at a low volume.
Pros
- Stunning power with great handling of even very demanding speakers
- Excellent build quality and features

Integrated Amplifiers – Buying Guide
Features
Before spending a grand on an integrated amplifier, it is worth evaluating your immediate and future needs for your hi-fi system. For instance, the lack of a wireless connectivity option is not futuristic for an amp. Let’s discuss some major features below:
Inputs Options
These are the links between your amplifier and the signal source. Inputs options fall under the following categories:
- Analog audio inputs
- RCA ports: Standard connections for analog components
- RCA phono ports: specialized port for connecting a turntable
- Balanced XLR ports: have balanced signal path for connecting high-end and professional audio components
- Digital audio inputs
- Optical port: mainly for TC connections
- Coaxial port: connects your signal source to the Digital-to-Analog converter.
- USB Type-A: connection for mobile devices and USB thumb drives

Read our article on Audio Outputs for more details on various input/output modalities and their functionalities.
How Much Should You Spend?
The answer to this question is personal. We agree your budget is a major consideration, but spending a few more dollars for improved power is worthy. Besides, getting the best integrated amplifier requires a balance between your audio requirements and your budget.
Prices are not always indicators for the best product, and essentially, there will be a point of diminishing returns. Besides, for home or office use, a combination of good speakers and an amplifier with at least 100 watts per channel suffice well.
Integrated Amplifier Features Explained
RMS vs. Peak Wattage
Wattage refers to the power output of the amp. Simply put, it’s a measure of the loudness of an amp, and consequently, the speakers it can power. Thus, a very important feature to know while building your sound system.
RMS wattage shows the output power the amplifier can manage over a long period, while peak wattage is the maximum output power, measured in short periods. The two are important in selecting speakers to use with your amplifier, but RMS wattage is a better indicator of the power your amp will manage daily.
DACs
Digital to Analog Converters changes the signal from machine form (zeros and ones) to electrical signals detectable by your speakers. For a powerful sound system, you need a good DAC. While most media players and smart devices have inbuilt DACs, the quality of their output may be insufficient for crispy sound output.
Check to see if your preferred amp has an inbuilt DAC, or you may need to buy a separate one.
Stereo Amp classes
While shopping for a good amplifier, you’ll notice every amplifier has a class classification like Class T, Class A, tube, and others. Though it’s a handy thing to understand about amplifiers, modern integrated amplifiers have enough power to overcome any class limitations.
You can comfortably go for any amplifier class as long as it has the number of channels you need, fits in your available space, is set up nicely, and has enough input options. In brief:
- Class A: A common type with low distortions, though somehow power inefficient. Class A amplifiers keep both output stages on always.
- Class B: Only one output stage is on at a time, hence have better power efficiency than Class A. The downside is sometimes there are high distortions at frequency crossover points.
- Class A/B: This is a hybrid between Class A and B, leading to a reasonably power-efficient circuitry with limited distortions.
- Class D: This class contains highly efficient active transistor switches; thus, they are usually more compact than other classes. Also, they are lighter and emit less heat. Class T is a variation of Class D, made by Tripath.
- Monoblock: This class is usually for pricey models with one amplifier powering a single channel, unlike other amplifiers where both channels get power from the same amplifier. The result is more power and better sound.
- Tube (valves): Tubes are tiny glass cylinders common in headphone amps that produce soft and warm sound typical with tube amplifiers. They rarely appear in stereo amps.
Channels
A channel refers to a single audio output of sound on the amplifier. For instance, a 2-channel amplifier has two audio outputs for speakers. The more the channels, the more the speakers you can connect to and maintain good sound quality.
But it doesn’t mean you can’t connect more than one speaker in a single channel, it’s possible, but the sound quality won’t be that great.
Total Harmonic Distortion (THD)
THD, sometimes with an N for noise, measures the difference between the sound signal entering the amplifier and the exits’ signal. In other words, it measures how much the amplifier alters the input signal.
Essentially, this number should be very low, or else the input signal will greatly differ from the output. THD is almost negligible in modern amps, so you have nothing to worry about unless the THD gets over 1%.
Signal-to-Noise Ratio (SNR)
Like any other electric appliance, an amplifier makes some noise as the electrical components run. SNR measures how loud the electrical components are in relation to the sound output of the amp. Essentially, manufacturers’ aims to make this noise unperceivable so that you hear more music. The larger the number (in decibels), the better the amplifier.
Crosstalk
This is a measure of how well an amplifier separates the sounds from the inputs to the channels. In short, it measures the “leak” between channels. Crosstalk ratings are in decibels with a negative sign on them.
The larger the negative number, the lower the leakage. This measure is more important than SNR and THD+N as if the separation is bad the sound output becomes muzzy.
Integrated amp weight
Good amplifiers have great power management, and the power management equipment is often heavy. Therefore, an easy indicator of a good amp is its physical weight. Though modern power management components are lighter, and hence the weight rule is not hard and fast.
Conclusion
It is clear that there are excellent contenders for integrated amplifiers in the sub $1000 space. Whether it is budget, power, features or aesthetics, this guide should help you narrow down the best amplifier for your personal tastes in your aim for a hi-fi set up.
Integrated amplifiers not only improve your sound playback from speakers but also enhance convenience with the various connectivity and control options available.
Designed to seamless integrate into any hi-fi listening set-up, integrated amps will serve you for many years to come.
