1. FiiO K7

The FiiO K7 is a headphone amplifier and DAC in one. Use it as a link between your computer, music player, smartphone, etc. as an input source and powered speakers or headphones as an output source to benefit from a high-quality, space-saving audio system. The THX AAA 788+ amplifier technology achieves a remarkable output of up to 2000 mW and can thus confidently drive any earphones or headphones with both low and high impedance and generate a musically thrilling sound. The two AK4493S digital-to-analogue converters from the Japanese manufacturer AKM process high-resolution audio signals up to 32 bit and 384 kHz as well as DSD.

The pleasantly warm timbre of these DACs with their detailed fine resolution will make you discover and love your music. The many connection options make the FiiO K7 the interface for your audio equipment. Computer, notebook, music player, smartphone, tablet etc. can be connected to the USB input, the RCA inputs as well as coaxially or optically. Cinch outputs are available for connecting speakers. Headphones are connected to the front of the K7 at the 6.3 mm or the balanced 4.4 mm jack. A 6.3 mm to 3.5 mm adapter is included in the scope of delivery so that headphones with 3.5 mm plugs can also be used.

On the front of the FiiO K7 there is a control for two gain settings, so that headphones with different sensitivities can be operated optimally. Another switch can be used to change between the input sources (USB / optical / coaxial / line). The large metal rotary wheel on the front of the K7 allows precise adjustment of the volume. With its solid aluminium housing in discreet black and its compact dimensions, the FiiO K7 fits just as well on the desk as it does in the hi-fi rack.
