    All About Headphone Amplifiers Desktop, 3.5mm Mini-Jack


    Portable headphone amplifiers are the ideal tool for music lovers ready to take their listening experience to the next level. By amplifying the signal from a portable music player—such as iPods and Sandisk players—a headphone amplifier increases the dynamic range of your music to expose the nuances of a recording. While not all headphones need a headphone amplifier, headphones of impedances around or above 100 ohms will either benefit or necessitate an amplifier. Whether your files are in FLAC or MP3, a headphone amplifier unearths aural detail to give listeners a complete portrait of their recordings by feeding the driver with enough current to move as it was designed. Headphone amplifiers also offer the added benefit of enhancing a headphone’s sound stage, allowing for better instrument separation and placement on a three dimensional plane. When headphone amps are integrated with Digital to Analog Converters (DACs), the overall quality of a recording can be remarkably enhanced. Because headphones can only reproduce currents into sound, any device capable of storing and reproducing digital audio is equipped with a DAC. Nonetheless, factory stock DACs are not always of quality and headphone amplifiers with integrated DACs can help resolve this issue. Often featuring higher resolution and bit rates, portable headphone amplifiers with DACs decode digital signals with greater accuracy resulting in a reproduction that is richer, complex, and refined. Headphone amplifiers in tandem with DACs are an invaluable tool for music lovers and audiophiles whether on-the-go or at home. We offer a large selection of quality devices from respected manufacturers such as NuForce and FiiO to ensure that you will find an amp or DAC that will meet your demands of quality and value. Whether you own on-ear headphones, over-ear headphones or any other headphone type, Sonic Electronix has the amp that will fit your need.
