CY-5100dsd MK-III DAC

Reference DAC, digital pre-amp, headphones amp

Reference quality, native DSD and DXD support, amazing emotional involvement!

The best DAC got even better!

The CY-5100dsd MK-III sets the highest standards for digital to analogue converters. Hear details you never noticed before. Be stunned by the deep and wide sound stage. For MK-III the analogue stage was redesigned to bring unparalleled smooth, warm sound. New is the chooice between the ultimate precision or acourstic warm sound.

The CY-5100dsd is also a digital pre-amp with advanced digital lossless volume control. When desired, the CY-5100dsd can directly feed an end-amplifier. An optional analogue volume control board is available to bring the ultimate pre-amp performance for headphones and end-amps.

With the build-in dedicated headphone amplifier with independent volume control, the CY-5100dsd is the perfect combination for demanding headphones.

MK-III version adds DoP DSD and a high contrast OLED display. DSD can be played over USB but also over the SPDIF connections using DoP. Now almost any media server can support DSD!

At reference quality level, the CY-5100dsd will take center stage.

Upgrade existing transport: connect using the SPDIF or TOSLINK input and instantly enjoy the obvious improved sound as jitter from the source is removed and the fully customized digital filter can set to match your personal music taste and existing equipment.

Replace old DAC:  especially when your old DAC is more than 5 years old, the difference in sound quality will be dramatic.

To ‘up-end’ your existing music server, player: if you own a media player (server) system, you can now enjoy improved quality sound. Simply connect your music system’s digital output to the DAC. Trough DoP, you can playback DSD files directly from most media players.

Works great with Raspberry PI based music players players: the CY-5100dsd works great with Raspberry PI based (MPD) music players such as MoOde Player in both PCM and DSD.

To use your computer as high quality music source:  the CY-5100dsd DAC’s supports up to 384kHz and DSD128 formats, so you have the option to do all digital filter processing inside the computer for superior sound or play the highest resolution files available today.

88.2 kHz, 176.4 kHz, 352.8 kHz (DXD) sample rates are also supported; use a player like the Foobar 2000 to play super resolution files in bit-perfect fidelity.

The CY-5100dsd MK-III supports DoP, so playing DSD music files in Apple MAC-OS is a breeze.
