How to Choose the Best Power Amplifier?

When it comes to purchasing a new power amplifier for your system (or) simply figuring out which power amplifiers are best for your requirements, there are a handful of essential factors to consider. 

Look at some of the key features entailed below which can significantly impact your listening experience.

Best Power Amplifiers Buyers Guide

1. Power Output

Generally, an amplifier’s power output stipulates how loud your speakers can sound. It is typically measured in watts per channel. Ensure that the power amplifier you pick meets the requirements of your speakers and the size of your space for adequate sound levels without distortion.  Consider the subwoofer output as well if you have external speakers. 

Finally purchase an amplifier with a power output corresponding to your space’s size, kind of speakers, and subwoofers for maximum performance. 

2. THD and SNR

THD (Total Harmonic Distortion) measures the level of distortion created during the amplification process whereas, SNR (Sound-to-Noise Ratio) represents the difference between the output power of the amplifier and the background noise it generates. 

Always go for the amplifiers with low THD values that offer clear and genuine sound reproduction preserving the original audio and higher SNR for a cleaner and immersive listening experience. 

3. Audio Quality

Mostly, power amplifiers shouldn’t generate any audible noise while using them. And most of them combat this problem through various means. Moreover, Total Harmonic Distortion (THD) and Signal-to-Noise Ratio (SNR) play a major role in producing clean audio. 

So, always prefer the amplifiers with low THD and high SNR to ensure clean and clear audio reproduction.

4. Impedance

Impedance is the resistance of the speakers to the flow of electrical current which is typically measured in ohms. Matching the output impedance of the amplifier to the impedance of your speakers is important for preventing power loss and ensuring maximum performance. Mismatched impedance can cause inefficiency and damage to both the amplifier and the speakers

That’s why prefer an amplifier that matches the impedance of your speakers (or) one that comes within the acceptable range.

5. Built-In Protection

Built-in safeguarding circuits in amplifiers protect against overloading, overheating, and short circuits. These features not only prevent the amplifier from harm but also add to its overall durability.

6. Connectivity

Amplifier manufacturers will usually include a wide variety of features and connectivity options such as Bluetooth, phono inputs and outputs for turntables, a USB port, Wi-Fi streaming, or other specific features to match your audio sources and devices. 

Therefore check the connectivity type you are looking for to avoid any sort of inconvenience. Moreover, if you’re looking for specific inputs, like RCA inputs, check before making a purchase. 

7. Speaker Sensitivity

If the speaker sensitivity is low, additional amplification will be required to achieve greater listening levels. Consider the impedance rating of the speakers. If your speakers’ impedance is less than four ohms, you should opt for a high-current amplifier.

8. Channels

An amplifier’s channel count impacts how many speakers it can drive. A 2-channel amplifier can power two speakers, whereas a 5-channel amplifier can power five. Prefer the amplifier with adequate channels depending upon the speaker count of your setup. 

9. Frequency Response

An amplifier’s frequency response affects the range of frequencies it can reproduce. Choose an amplifier with a frequency response that corresponds to the frequency range of your speakers.

10. Amplifier Class

Different amplifier classes (Class A, Class AB, Class D, and so on) have different efficiency, heat production, and audio quality characteristics. 

  • Class A amplifiers are ideal for this, but they have a power efficiency of just 20% and emit a lot of heat. 
  • Class B pulls and pushes, resulting in around 75% efficiency, but substantially greater THD levels. AB achieves the ideal balance. 
  • Class D is 90% efficient, however, the sound quality is inferior to others. As a result, they are better suited for low-end HTiBs. 

Choose the class that best matches your listening preferences and energy needs.

11. Added Features

Some amplifiers have equalizers, bass and treble settings, and digital inputs. These capabilities provide you additional control over your system’s sound. if you are looking for added convenience, prefer the amplifier models with these features for seamless usability. 

12. Budget

This is one of the most important factors to consider before making a purchase. Make a list of your requirements, needs, and budget prior, and look for brands and models that fall within your price range. After determining your budget, check for the best value for the features and performance you require. Keep in mind that more expensive models may not necessarily give better sound quality for your specific needs. 

A good power amplifier can cost over $1,000, but for $100 you can obtain something half as good for a tenth of the price.

Deeming the aforementioned factors will help you in choosing the right power amplifier that matches your needs. Additionally, we advise you to check on other things like brand, reputation, track record, customer reviews, reliability, headroom, and crosstalk while selecting the device.

Best Power Amplifier –  FAQs

1. What is the ideal power output for a power amplifier?

Ans: The ideal power output is determined by your audio setup and listening preferences. For most home audio systems, a power output of 50 to 100 watts per channel is enough. If you have larger speakers (or) a large listening area, you may want to consider amplifiers with more watts per channel to provide enough headroom and dynamic performance.

2. How much power do I need for my speakers?

Ans: The amount of power required is determined by the sensitivity of your speaker and the size of your listening environment. Most home audio installations require an amplifier with 50-100 watts per channel. The majority of the amps on our list are in that price range, and the most expensive stereo amps may provide more than 200W of power, which is more than enough for any single listening room.

3. Do more expensive amplifiers always sound better?

Ans: While more expensive amplifiers may have greater build quality and more features, sound quality can be subjective. It is essential to test out many models to pick the one that best meets your needs.

4. Can I use the amplifier with different types of speakers?

Ans: Most power amplifiers can be used with a wide range of speakers as long as the impedance and power ratings are properly matched. Most manufacturers will specify the impedance and power specifications on their stereo amps, so double-check before buying.

5. Can I connect my smartphone or tablet to the amplifier?

Ans: Yes, many modern amplifiers offer Bluetooth (or) other wireless connectivity options for streaming audio from smartphones, tablets, and other Bluetooth-enabled devices. Check to see whether it has Wi-Fi streaming capabilities before you buy.

6. What are the advantages of Class D amplifiers?

Ans: Class D amplifiers provide various advantages, including great efficiency, low heat generation, and a small footprint. 
* They are more energy-efficient than other amplifier classes because they employ pulse-width modulation to transform audio signals into digital format. 
* Because of their small form and cooler operation, they are appropriate for a wide range of applications, including home theaters and automobile audio systems.
