As the focus of our website attests, an increasing number of music lovers are buying, storing and listening to music through their computer, media server or personal music player (iPod).  Many are also digitally distributing their music using a Sonos, Squeezebox, or one of a host of digital music distribution systems available on the market.  While this is a great way to explore and appreciate music, it has typically been done at the expense of sound quality.  Until now music lovers have been forced to rely on the inferior digital to analog converters (DACs) and sounds cards contained in those devices.  As a result, their musical enjoyment has dramatically suffered. Music Hall designed the DAC 25.2 to directly address this problem and to significantly improve the sound quality of the digital music played on your system.  

By uniting a state of the art digital to analog converter with a tube based analog audio output, Music Hall produce the clarity and precision of a 24bit DAC with the warm rich open sound people love of tubes.  The DAC 25.2 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 Zone Player, Squeezebox Network Music Player or a CD/DVD transport and it will output two channel stereo analog. 

The DAC 25.2 features the latest Texas Instruments (formerly Burr-Brown) PCM 1796 24bit/192kHz, advanced segment, stereo audio digital to analog converter. This processor features 123dB dynamic range, an 8x oversampling digital filter and just 0.0005% total harmonic distortion.  The DAC 25.2 can upsample to either 96kHz or 192kHz via a user selectable front panel control.  To achieve the best sound Music Hall uses an advanced asynchronous reclocking and anti jitter control system upstream of the PCM 1796 DAC.  For this system they are using the Philips 74HC574 in conjunction with the TI SRC4192 asynchronous sample rate converter, featuring a high precision active crystal oscillator master clock.  The DAC 25.2 also features a large r-core high current oversize power transformer.  Finally, a high quality headphone output is provided for personal listening.
