Thinking about purchasing a headphone amp? Powered speakers usually remove the necessity for an amp in your speaker setup, but headphones sometimes warrant a headphone amp because they don't have the benefit of a power source. How do you know in case you need a headphone amp? To get a nice suggestion of whether or not you need a headphone amp, you need to understand a tiny about how sound processing works.
Understanding sound processing: why a headphone amp is useful.
When you are listening to music from a computer or other digital source, vital piece of equipment is the DAC, or digital to analog converter. The DAC converts the digital language to electrical current that makes the magnets in your headphones vibrate, producing sound.
Most soundcards include a built-in DAC to decode signals and produce sound, but the signal is weak to be used when it comes directly from the DAC. It's to go through an amplifier to produce sound for you to listen to music from your headphones or speakers. Powered speakers include a built-in amplifier to boost the signal power so that you can actually listen to it. However, most headphones don't have a power source, so you'll either must depend on some kind of onboard headphone preamp, or you might need a separate headphone amp in order to listen to signal that comes from a DAC.
Why having a nice headphone amp matters.
Headphone amplifiers don't increase the volume of sound. Headphone amplifiers control the electrical signal that goes to your headphones and produces sound. This matters because a exact electrical signal is much more correct than an imprecise or fluctuating signal. Therefore, you listen to better quality sound with a nice headphone amp than with a poor, as the electrical signal transmits more exactly to your headphones. Plenty of good-quality headphone amps also give you the choice to increase or decrease the bass independently, to produce the sound exactly as you like it.
possibilities usually come from having a nice headphone amp: either you'll listen to your music at a lower volume because it basically sounds better and you can make out individual details without cranking it, or you'll listen to it at a higher volume but enjoy sound free from distortion. Either way, headphone amplifiers provide a win-win situation; high-quality sound that you can enjoy at a broad range of volume levels, not very low or very high.
Be cautious with the volume levels on your headphone amp.
Your ears are the most fragile piece of equipment in your sound setup, so don't use a headphone amp as an excuse to blast music loudly and destroy your hearing. Invest in a good-quality headphone amp that might be a bit more expensive, but provides better sound quality so you needn't listen to it loudly to listen to it. And keep in mind - always be cautious along with your volume levels to keep away from damaging your hearing.
