dac25.3

BY UNITING A STATE OF THE ART DIGITAL TO ANALOG CONVERTER WITH A TUBE OUTPUT WE PRODUCE THE CLARITY AND PRECISION OF A 24BIT DAC WITH THE WARM RICH OPEN SOUND PEOPLE LOVE OF TUBES.

The dac25.3 has 4 digital inputs which can accept any coax (s/pdif), optical, XLR (AES/EBU), or USB digital input from an iPod transport, computer, media server, sonos, squeezebox, or CD/DVD stereo transport, and it will output two channel stereo analog.

The dac25.3 upsamples to either 96kHz or 192kHz, which is user selectable on the front panel. To achieve the best sound we use an advanced asynchronous reclocking and anti-jitter control system upstream of the PCM 1796 DAC. For this system we are using the Philips 74HC574 in conjunction with the TI SRC4192 asynchronous sample rate converter, whose master clock is a high precision active crystal oscillator. The dac25.3 also features a large R-core high current oversize power transformer.

improved sound quality

Today an increasing number of music lovers are buying storing and listening to music through their computer, media server, or personal music player. We designed the dac25.3 to directly address this trend and to significantly improve the sound quality of the music played on these systems.
