Best Audio Component Amplifiers Buying Guide
Before choosing the best audio component amplifier you should consider the following options:
1. Power rating: The amount of power your amplifier must have depends on the speakers you are using. The first step is to check the manufacturer’s specifications of your speakers and find the recommended amplifier power rating.
2. Before making a purchase, make sure the amplifier can handle the total power consumption of the speakers. The total power consumption is the sum of the rated power of the speakers. The amplifier must have a higher rating to accommodate the speakers.
3. Decibels: The decibel rating of the amplifier is also important. You will find amps with different decibel ratings.
The higher the decibel rating, the higher the efficiency of the amplifier. The higher the efficiency, the higher the sound quality.
4. Wattage rating: It is also important to check the wattage rating of the amplifier. Higher wattage rating means the amplifier has higher power.
5. Voltage and current: The voltage and current rating of the amplifier should also be considered. The amplifier must be capable of handling the total current of the speakers.
A higher current rating means the amplifier can handle higher power. Higher power means better sound quality.
6. Gaining control: The amplifier you choose should have a gain control knob. The gain control knob is important because it lets you adjust the volume levels.
The knob can also be used to limit the volume levels of the speakers so that they don’t reach the maximum output. This helps in protecting the speakers from damage.
7. Bass boost: If you need an amplifier that offers bass boost, make sure you get one. Bass boost is essential because it helps in improving the bass sound of the music.
Without bass boost, the music will sound very thin. The amplifier will make the music sound great with enhanced bass.
8. Voltage and current protection: The amplifier must have a protection feature for both voltage and current. This feature is essential for preventing damage.
The amplifier should cut off the speakers when the current and voltage reach their maximum limit. This prevents the amplifier from burning out and also prevents the speakers from getting damaged.
9. Warranty period: Last but not the least; always check the warranty period of the amplifier. The longer the warranty period, the better.
