Music Hall DAC25.3: Digital Done Right
The Detail, Warmth and Musicality Only Tubes Can Provide
This Killer 24bit/192k Upsampling DAC Can Now Handle 24/96 USB Files
Today 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 Wadia iTransport, Sonos, Squeezebox, or one of a host of digital music distribution systems available on the market. This is a great way to explore and appreciate music but generally it’s done at the expense of sound quality. Until now, music lovers have been forced to rely on the terrible built-in digital-to-analog converters (DACs) and sounds cards contained in those devices, and as a result, their musical enjoyment has dramatically suffered. Music Hall designed the dac25.3 to directly address this problem and to significantly improve the sound quality of the music played on these systems.
By uniting a state-of-the-art digital-to-analog converter with a tube output stage the dac25.3 produces the clarity and precision of a 24-bit DAC with the warm, open and natural sound of tubes. The dac25.3 has 4 digital inputs - Coax (SPDIF), Tos-Link, XLR (AES/EBU) & USB digital input for ultimate compatiblity with virtually any source. When input a digital signal from an iPod transport (Wadia), computer, media server, Sonos, Squeezebox, CD or DVD transport, the dac25.3 outputs gloriously rich two channel music either to your system via the RCA or XLR (balanced or single-ended) output jacks or through its own built-in, high-quality headphone amplifier.
The dac25.3 features the latest Burr-Brown PCM1796 24bit/192k, advanced segment, stereo audio DAC. This processor features 123dB dynamic range, an 8x oversampling digital filter, and achieves a miniscule 0.0005% THD. The dac25.3 upsamples incoming signals to either 96kHz or 192kHz at 24 bits, with 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 PCM1796 DAC, a Philips 74HC574, in conjunction with a Ti SRC4192 Asynchronous Sample Rate Converter, whose master clock is a high precision active crystal oscillator. To ensure a lifetime of flawless operation, the dac25.3 uses an oversized, high current power supply.
