FiiO

The FiiO S15 is a DAC/streamer with a high-quality analog section and a balanced output on XLR connectors. The new product is Roon Ready certified and supports DLNA and AirPlay. In addition, the FiiO S15 can be used as a preamplifier (has a digital volume control), which allows you to connect the player directly to a power amplifier or active loudspeakers.

Desktop DAC and Headphone Amplifier FiiO K17 offers Flagship AKM AK4191 + AK4499EX x 2 DAC, 31-band high-precision lossless PEQ, discrete class AB transistor current amplification headphone amplifier and streaming functionality.

Digital-to-analog conversion is implemented on two AK4497S chips from the Velvet Sound series by the Japanese company Asahi Kasei. The dual mono configuration provides a fully symmetrical and differential analog path. The analog and digital parts of the circuit, as well as power supplies, are located on separate boards.

The QX13 uses low-noise ES9312 stabilizers and four integrated INA1620 chips to minimize interference between channels. Two OPA1692 amplifiers are responsible for stable dynamics even under heavy load. Supports PCM up to 32 bit/768 kHz, DSD512 and full MQA decoding.

The device is based on the latest discrete technology R2R (resistor ladder) and provides, according to the manufacturer, a class-leading sound level in a compact and stylish case. A nice touch is that there is a round window on the top wall of the case, through which the entire configuration of the chipset is visible.

An inexpensive DAC with a Tiny headphone amplifier, designed to work with smartphones or tablets. The novelty is a so-called USB-C DAC of the T-Bar format, combined with a headphone amplifier, and is available under the Snowsky sub-brand.

The FiiO Warmer R2R external DAC uses a fully differential proprietary 24-bit R2R matrix consisting of 192 thin-film precision resistors with a tolerance of 0.1 percent and a temperature drift of 30 ppm. This circuit is fundamentally different from typical delta-sigma chips and, according to the manufacturer, is designed to provide a more harmonious, detailed sound.

The FiiO SnowSky Melody DAC is equipped with two CS43131 DAC chips from Cirrus Logic, each of which is responsible for its own channel. The signal is processed by a powerful DSP, which not only provides a clean conversion, but also makes it possible to use a 10-band parametric equalizer (PEQ). Settings can be made through the FiiO Control mobile gadget app or the web interface, and presets can also be saved and even shared. Audio decoding in PCM format with parameters up to 32 bit/384 kHz, as well as DSD up to DSD256 is supported.
