Buyer’s Guide
Whether you are buying an amplifier for speakers, headphones, or any other audio device, there are a few important factors to consider. As some are more important than others, let’s discuss the ones that will help you get the best amplifier for your needs.
Versatility
In every case, having an amplifier with various inputs and connections will definitely increase the user’s experience. Even though most amplifiers include 3.5mm AUX input, the best way to use headphones is with 6.3 mm input. Also, the amplifier with proper inputs can be used for multiple purposes such as home sound systems, DIY projects, or even gaming setups.
Considering that the latest amplifiers include every connection required, it is not the same for more affordable ones. Altogether, inexperienced users should get an amplifier with default inputs and a stable connection with additional devices such as Bluetooth.
Power output
The power output might not be a huge factor for casual users. Still, enthusiasts and audiophiles should definitely consider the power requirement. Every speaker comes with a specific wattage, which is the main indication of the speakers’ power output. Before deciding on a particular amplifier, it is important to consider how much power is required.
In other words, the bigger the area, the more power is necessary for complete coverage. That said, that is also the main reason to get a more powerful amplifier. There is no reason to avoid amplifiers with more power, but they are usually more expensive.
Signal & Noise
Considering that the noise cannot be avoided in most cases, getting an amplifier with a good signal-to-noise ratio is possible. The signal is basically the music the user is listening to. The main goal is to get clear and pleasant sounds.
On the other hand, noise refers to the sound produced by the amplifier while playing music. Getting an amplifier with a good signal-to-noise ratio improves the signal and reduces the noise. That said, the noise will not have a negative impact while listening to music. Also, some amplifiers might produce a higher noise near additional devices.
Subwoofer
Buying a subwoofer is not required for standard setup, but it is necessary for advanced use. Most high-end amplifiers include a subwoofer for better sound quality and performance. Getting an amplifier with a subwoofer is a more expensive option.
Still, it will provide a high value for experienced users. The subwoofer does not draw power from the amplifier as the only thing required is the RCA cable.
THD+N
In other words, total harmonic distortion plus noise determines how good the original recording is produced by the amplifier. When it comes to the THD+N, it is very simple high value should be avoided. That said, getting an amplifier with low THD+N is the best thing to do. Without any question, this is a huge factor for casual and more experienced users.
