The FiiO E10 was one of the first compact USB Amp/DAC combinations on the market. Now, that original Fiio has been upgraded with many new & improved features. The sound reproduction for an Amplifier / DAC in this price range is unrivaled.
The FiiO E10K USB DAC headphone amplifier includes a selectable bass boost and low-pass filter which allows you to fine-tune the audio output. The new DAC chip efficiently enhances the linearity of the internal filter and reduces delay and produces better audio output as a result. Unlike many bass-boosts that introduce noise to the signal, the E10K's bass-boost functionality is ultra-quiet. All of this provides for an excellent aural experience when using in conjunction with high-res audio.
The bass of the E10K is tighter than the original. The E10K provides clear sound, a bigger soundstage, lighter bass, and can power most headphones efficiently. Although the sound quality isn't as good as units costing several times the Fiio E10K's price, in this price range, the Fiio really can't be beaten for sound quality, build quality & features.
The all new E10K has LMH6643 op amp which gives an enhanced transient response and driving power. The amplifier works on an advanced operating system which is plug and play enabled, thus not needing any drivers to be installed.
The Fiio E10K is both portable and compact in design. It has a standard Micro USB for power supply. The output is 200 mW at 32 ohms. The frequency response is 20Hz to 20KHz. The headphone impedance recommended is 16-ohm to 150-ohm. The box comes with a DAC/Headphone amp, USB cable, Rubber feet, owner's manual, and Warranty card.
The Fiio E10K is a great entry level AMP/DAC that provides you with great sound, a range of features & the build quality you'd expect from a Fiio device.
