Musical Fidelity M1 DAC which is the new and improved as of a November 2011 street date namely adding an Asynchronous USB input capable of handling 24-bit/96kHz data. The M1 DAC is also of the upsampling variety meaning it takes every incoming signal and converts it to 24-bit/192kHz using a Texas Instruments Burr-Brown SRC4392 sample rate converter before handing off to a pair of Texas Instruments Burr-Brown DSD1796 D/A chips in dual-differential mode. The upsampling process uses buffers and mathematical processes to step the incoming signal up to a higher sample frequency, thus shifting the noise to a frequency that is much higher than that of the audio band, and therefore easier to filter without doing as much damage to the original signal.
In addition there is another feature utilized in this process by Musical Fidelity, and that is reclocking of the data. Because the data is being temporarily put into a buffer and re-packeted during the upsampling process, it can be (and in the M1DAC’s case, is) slaved to a more accurate master clock source inside the DAC, thereby ensuring there is virtually no jitter imparted to the signal from the input buffer to the DAC chipset itself.
Silver front this one and very lightly used. Sounds very good and sports a comprehensive set of......
Input: (2) S/PDIF (Coax, Toslink), Async USB, AES Balanced.......
Output: (1) pair RCA, (1) pair XLR Balanced connectors.
Price is £200 plus £12 postage if required.
