The MUSE T-Amp is a so-called Class T integrated amplifier, based on the TA 2021 chipset.

  the chip makes use of a kind of "Digital Power Processing",
this is, more or less, a Class D amplifier with high rate switching properties.
 That is why they put the word "digital" into it.
Actually, there's nothing really digital inside, not in terms of D/A conversion.
You can view the official TA2021 datasheet, with detailed tech specs, 
The MUSE T-Amp is nothing else than a pure and simple application suggested by the chipset datasheet.
 No magic.
