We have improved the DAC MK 5 by adding DSD 256 playback capability. All units shipped after September 1st include this upgrade at no extra cost.
The DAC now plays PCM 44 through 192 along with DSD 64, 128, and 256 seamlessly and interchangeably.
The upgrade requires upgrading two microprocessors and unfortunately this is not a do it yourself process.
However, we will do the upgrade free of charge except for shipping if you return your DAC to us for this upgrade.
Note that DSD 256 is not supported by the current Apple operating systems, but it works just fine with a PC using our free driver software.
Please call us at 651-330-9871 before shipping so we can plan a return time that will minimize your out of service time.
Thanks for your continuing support.
