Music Hall DAC 25.3


The Music Hall 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, CD/DVD in stereo transport, or music hall’s own cd35.2 compact disc player, and it will output two channel stereo analog.

The dac25.3 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 8 x oversampling digital filter and just 0.0005% thd. 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. A headphone output is provided for convenient personal listening.
