Want to start your journey to high-quality sound? The first step is to choose the right amplifier.
An amplifier is the most important part of a sound system, amplifying the signal and ensuring that the sound is clear and powerful. Even the best speakers won't work properly without a well-matched amplifier. Here's what you need to know:
- Power (W): Depends on the size of the room and the sensitivity of the speakers. For small rooms, 30-50 W is sufficient.
- Impedance (Ω): Must match the speaker specifications (usually 4, 6, or 8 Ω).
- THD and SNR: Low distortion (THD) and good signal-to-noise ratio (SNR) ensure clean sound.
- Types: You can choose between integrated amplifiers (simpler and cheaper) or discrete components (more flexible but more expensive).
AUTOGARSAS.LT offers a wide selection of amplifiers, starting from models for ~300 €. In the Kaunas showroom you can test the equipment and get professional assistance. Whether you have a limited budget or are looking for higher-end solutions, the right amplifier will help you enjoy quality sound.
Main specifications of amplifiers
Basic specifications worth knowing
Amplifier specs can be confusing, especially if you're new to audio technology. However, a few key metrics will help you better understand how an amplifier will affect your listening experience.
- Power (W) : This is the amount of energy delivered to the speakers. When choosing an amplifier, it is important to consider the size of the room and the sensitivity of the speakers to ensure that the system operates efficiently.
- Impedance (Ω) : A measure of electrical resistance. The amplifier must be matched to the impedance of your speakers (usually 4, 6, or 8 ohms) to prevent damage and ensure smooth operation.
- Frequency response (Hz–kHz) : Indicates what sound frequencies an amplifier can reproduce. Since human hearing spans the range of 20 Hz–20 kHz, an amplifier should operate within this range to reproduce the full audio spectrum.
- Total Harmonic Distortion (THD) : Measures how much an amplifier distorts the original sound. The lower the THD, the more accurately the sound is reproduced. For example, the Benchmark AHB2 model has an extremely low THD+N of less than 0.00013% [4] .
- Signal-to-noise ratio (SNR) : Indicates how much the desired signal exceeds the background noise. A higher SNR means cleaner and more detailed sound [1] [2] .
How these specifications affect sound quality
Knowing how each feature affects the sound will make it easier to choose the right amplifier.
- The importance of power. The right power depends on the size of the room and the sensitivity of the speakers. For example, if you are using high-sensitivity speakers (90+dB SPL @ 1W/1M), background noise from the amplifier may be noticeable, so it is important to choose a model with a high SNR [5] .
- The influence of THD and SNR. An amplifier with a THD of less than 0.1% will not distort the sound noticeably. However, higher THD can cause intermodulation distortion, especially in complex music [3] . A high SNR also reduces background hiss or hum, ensuring a clear sound [2] . Interestingly, loudspeakers often have higher distortion levels - the human ear usually detects distortion when it exceeds 3%, and for low frequencies this figure can reach as high as 10% [3] [5] .

Matching amplifiers and speakers
How to properly connect amplifiers to speakers
To enjoy high-quality sound and protect your equipment, it is necessary to properly match the amplifier to the speakers. One of the basic rules is that the amplifier power should be 1.5-2 times higher than the speakers. For example, if your speakers are 50 W, the amplifier power should be between 75 and 100 W. This way you will avoid sound distortion and ensure smooth operation.
It is also important to pay attention to the impedance of the speakers. The most common models are with an impedance of 8 Ω, but you can also find 4 or 6 Ω options. If the amplifier and speakers are not properly matched in terms of impedance, this can not only degrade the sound quality, but also cause equipment failures.
Don't forget the sensitivity of your speakers either. High-sensitivity models (90 dB SPL or more at 1W/1M) will reach sufficient volume even with a lower-power amplifier, while low-sensitivity speakers will require more power to produce the desired sound.
Common mistakes to avoid
To keep your sound system working flawlessly, it is important to avoid the following mistakes:
- Inadequate power : If the amplifier power is too low, the sound will be distorted; if it is too high, there is a risk of damaging the equipment.
- Improper impedance matching : Improper impedance matching can cause overheating or even damage to the amplifier.
- Room size is ignored : small rooms do not need much power, while large rooms require more powerful equipment.
By taking these aspects into account, many problems can be avoided and the system can operate smoothly.

Integrated and separate amplifiers
Types of amplifiers
When you start to delve into amplifier specifications and speaker compatibility, it's important to understand the difference between integrated and discrete component systems. Many beginners wonder: should you go for an integrated amplifier or invest in discrete components?
An integrated amplifier combines a preamp and a power amplifier in one unit, making it a compact and convenient solution. Meanwhile, a standalone system consists of a separate preamp that controls the volume and sources, and a power amplifier that directly powers the speakers.
The key difference between these systems is their flexibility and future upgradeability. An integrated amplifier offers an all-in-one solution, while a discrete system allows you to modify and upgrade each part individually. Below, we’ll discuss how the features of these systems can affect your choice.
System comparison
Integrated amplifiers are often the best choice for beginners. They are easy to use, don't have to worry about compatibility between individual devices or additional cables - everything is ready to go. They are also often less expensive.
Separate components, on the other hand, offer more freedom. You can change or upgrade the preamp and power amplifier independently of each other, adapting to your needs or experimenting with different manufacturers. This allows you to more precisely tailor your sound system to your personal preferences.
| Aspect | Integrated amplifier | Individual components |
|---|---|---|
| Simplicity | All in one, easy to use | Compatibility knowledge required |
| Need for space | Takes up little space | Need more space |
| Expansion possibilities | Limited – requires changing the entire system | Can be replaced one component at a time |
| Sound quality | Fixed | Can be customized to personal needs |
| Starting price | Smaller | Larger |
Budget planning for beginners
When it comes to price, integrated amplifiers are an attractive option for those who are just starting out with their sound system. For example, AUTOGARSAS.LT offers quality integrated amplifiers in the price range of €300 to €500. This is a great start for your first system.
A stand-alone system costs more. For example, Audiolab offers the 9000A integrated amplifier for €1,999, while the 9000Q preamp and 9000P power amplifier kit costs €2,499. [6] This means that a system of separate components can be around 25% more expensive than an integrated solution.
It is often recommended for beginners to start with an integrated amplifier , especially if you are on a tight budget or are not yet sure where you want to take your system. Over time, as you gain more experience and understand your needs more clearly, you can move on to individual components.
Individual components also offer more options for the future. For example, using bridge mode in power amplifiers can increase output power and improve channel separation [6] .

FAQs
How to choose the right amplifier based on the size of the room and the sensitivity of the speakers?
When choosing an amplifier, it is necessary to pay attention to the size of the room and the sensitivity of the speakers , as these factors directly determine the sound quality.
The size of the room is one of the main considerations. The larger the room, the more power the amplifier will need to deliver clear and even sound. It is recommended to choose an amplifier with a power rating of 1.5 to 2 times the power of the speakers, especially if the room is spacious.
Speaker sensitivity , which is measured in decibels (dB), is a measure of how efficiently the speakers convert an amplifier signal into sound. If your speakers have a high sensitivity (e.g., more than 97 dB), they will require less amplifier power because they are more efficient at responding to the signal. However, speakers with low sensitivity will require a more powerful amplifier to achieve sufficient volume and maintain sound quality.
By properly matching the amplifier power to the room size and speaker sensitivity, you can achieve balanced, clear, and pleasant sound in your space.
What is the difference between integrated and discrete amplifiers, and which option is better for a beginner audiophile?
Integrated amplifiers are a great solution for those looking for convenience and simplicity. They combine amplification and control functions into a single unit, making them compact, easy to use, and often less expensive. This is especially true for beginners who don't want to delve into complex technical settings.
Meanwhile, separate amplifiers offer more options for those seeking higher sound quality. Since the amplifier and control unit are separate, they can be customized to individual needs. However, this option requires more space, a larger financial investment, and some technical knowledge.
If you're just getting started in the world of high-quality audio, an integrated amplifier is a good choice due to its ease of use and lower initial cost. However, if you plan to expand or upgrade your sound system in the future, it's worth considering separate amplifiers , which will allow you to achieve even better results.
How do I properly match the power and impedance of the amplifier to the speakers to avoid distortion and equipment damage?
To properly match the power and impedance of the amplifier to the speakers, it is necessary to pay attention to several important points:
- Amplifier power: Ideally, the amplifier output power should be slightly higher than the speakers' rated power. This will help prevent sound distortion and protect the equipment from overheating.
- Impedance matching: The impedance values of the amplifier and speakers must match. For example, if the impedance of the speakers is 8 ohms, the amplifier should also be designed for an 8 ohm load. If the impedance is not matched, there is a risk of overheating or even damage to the amplifier.
To ensure smooth operation of your equipment, always follow the manufacturer's recommendations and specifications. A properly tuned system will not only ensure better sound quality, but will also help prevent premature wear and tear on your equipment.
