I had heard about the DAC Magic, but did not realize that they offered a minimum=phase option.
They are using a low-cost DSP chip from TI with algorithms from Anagram of Switzerland. It looks like they are doing ASRC (Asynchronous Sample Rate Conversion) of all sources to 192/24 and then feeding it to the Wolfson DAC chip. I would assume that the Wolfson further oversamples it another 8x, but it is not clear if this is the case or not.
