Introduction of linear power supply
The linear power supply is a better choice for audiophiles. It has less noise and distortion than the switching power adaptor, however, during the AC to DC conversion and rectification process; there is a still minute amount of unavoidable noise and distortion. That’s because the AC power is required to traverse significant circuitry such as transformer, diodes, voltage regulators, and other components.
Specially designed for T20 and T20U, this optional power supply unit features a 48VA toroidal transformer coupled to a full-fledged regulatory circuit with eight audio grade NCC aluminum electrolytic capacitors: 5 x 2,200 µF @ AC input stage and 3 x 4,700 µF at DC output stage. The PSU provides abundant reserve to meet the demand when low frequency transients draw on high-current voltage.
To quote 6moons again: “When the PSUs were added to the pot, musicality thickened. There was more warm air filling up a more expansive soundstage. Bass got deeper, the midrange turned proportionally more pronounced to make the overall harmonics even richer.”
