New! Music Hall PH25.2 Headphone Amp

Marrying a gorgeous sounding tube pre-amp with solid-state amplification has been a technique for achieving unequaled sound quality in hi-end component audio since the advent of the transistor. While kicking around ideas for our new headphone amp we thought, why not try this same technique in a single component? We built one up and were blown away by the increased detail, clarity, and presence the design offered. The tube hybrid headphone amp was born. Hand assembled using the highest quality parts available the music hall ph25.2 will have you singing along with your favorite artists.

Music Hall 25 DAC/headphone amplifier.

This DAC has USB, coaxial, optical and XLR digital inputs as well as both single ended and balanced (XLR) outputs.

Here is some information directly from Music Hall regarding this little gem:

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 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 inferior digital to analog converters (DACs) and sounds cards contained in those devices. As a result, their musical enjoyment has dramatically suffered. We designed the dac 25.2 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 we 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, squeezebox, CD/DVD in stereo transport, or music hall’s own cd 25.2 compact disc player, 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 8 x oversampling digital filter and just 0.0005% thd. The dac 25.2 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 dac 25.2 also features a large r-core high current oversize power transformer. A headphone output is provided for convenient personal listening.
