CY-7100 Tube Edition DAC

Ultra Reference Digital to Analogue Converter

Simply the best sound, native DSD and DXD support, ultra precision stereo imaging.

Combines the best of modern and tube technology

The CY-7100 Tube Edition sets a new and very high standard for DAC performance. By combining modern DAC technology with a tube-only, non-feedback analogue stage, the finest musical details are uncovered. Warm, smooth, effortless sound.

There are no semiconductors in the analogue part of this DAC. All processing is done with an innovative 3-stage fully balanced tube processor.

In addition to exceptional sound quality, the CY-7100 Tube Edition has everything you expect from a modern DAC: 32 bits PCM, 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 ultra reference quality level, the CY-7100 Tube Edition will take center stage.

Upgrade existing transport: connect using the SPDIF or TOSLINK input and instantly enjoy your music as you never heard before. The digital filter can set to match your personal music taste and existing equipment.

Replace old DAC:  Hybrid technology makes the CY-7100 one of the best sounding DAC's in the world, the difference in sound quality is 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-7100 is designed to work 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-7100 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-7100 supports DoP, so playing DSD music files in Apple MAC-OS is a breeze.
