FiiO D03K Taishan

A quick and easy way to convert digital audio into high fidelity stereo analogue sound. Taishan D03K from FiiO is a simple DAC that converts coaxial or optical S/PDIF digital audio into a stereo analogue output, perfect for multimedia components such as TVs or CD/DVD/Blu-ray players that do not feature analogue output.

Taishan D03K features a digital input format switch and an LED to confirm digital signal lock. Power is supplied by an included external power supply. The input will accept up to 24-bit/192kHz resolution PCM digital audio, but Dolby Digital and DTS are not supported.

Dual RCA phono outputs can be connected to an amplifier, while a 3.5mm mini stereo output can be used to supply signal to a WLAN wireless headphone system. (The mini stereo output is not recommended for direct connection to conventional wired headphones.)

Ideal for interfacing modern digital devices with analogue systems.

A superb little DAC for any general pupose conversion
by ksr on 05/01/2017
Having bought a new TV, with no analogue audio out connectors, I needed a simple DAC to feed a stereo signal to my Yamaha mini component system.

Amazon appears to be awash with clones of the FiiO D03K, but many have poor reviews.

Finding a genuine item is more difficult, and thanks to hifiheadphones, I was able to get one at an excellent price.

It sits behind the TV, powered from one of the TV's USB sockets, and provides excellent sound quality when watching Blu-ray or DVD.

It is well made, and I am happy knowing I have the 'genuine article'
