M2Tech Vaughan DAC

M2Tech's long awaited ammiraglia, Vaughan DAC (est. US$6,000) was shown on silent display at Munich High End show.  The DAC features 32/384khz capability, asynchronous USB with custom drivers, word clock input, ST glass fiber input, 8 x DAC chip used (4 per channel), dedicated discrete headphone output, and 32-bit digital dithered volume control.
  • Sampling frequencies (kHz): 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384
  • Resolution: up to 32 bits (USB), up to 24 bits (other inputs)
  • Inputs: USB (B-type female), S/PDIF (2 x RCA and 2 x 75 Ohms BNC, dual AES for 384kHz), AES/EBU (2 x XLR dual AES for 384kHz), Toslink (2 x for dual AES), ST (2 x for dual AES), straight I2S, external master clock 
  • Outputs: single-ended on RCA and balanced XLR, plus a headphone ouput on 6.35mm jack socket
  • Power supply: 115-230VAC, optional battery PSU.
  • Controls and display: standby and select buttons, encoder, dual large matrix display to show locked frequency and selected input.
  • The Vaughan features 8 D/A IC's (4 per channel in mono mode). A digital dithered volume control will allow for using the Vaughan as a preamplifier. The headphone output is made with a discrete components amplifier.
  • Brushed aluminum case and grilled front panel
  • Dimensions: 440 x 80 x 440 mm.


An outboard Lithium-polymer battery power supply unit with low-noise regulators will power the Young DAC.  Housed in a matching case and to be called the "Young Supply" (right box in the picture below).  Whether it will also power the Vaughan is still unclear.  The left box is a prototype A/D converter called the "Joplin".
