This optional power supply unit features a 48VA toroidal transformer coupled to a full fledged regulatory circuit with eight audio grade aluminum electrolytic capacitors: 5 x 2200uF at AC input stage and 3 x 4700uF at DC output stage.
The PSU provides an abundant reserve to meet the demand when low frequency transients draw on high-current voltage. 6moons had the following observations about the PSU:
“When the PSUs were added to the pot musicality thickened. There was more warm air illing up a more expansive soundstage. Bass got deeper the midrange turned proportionally more pronounced to make the overall harmonics even richer.”
Hi Fi World magazine: "Consequently, I felt this was as good a time as any to switch to the upgrade PSU, which ad been sat beside the T20 on the shelf quietly warming up, and this improved things by quite a decent margin. A proper image appeared with depth, a good scale and nice sense of atmosphere."
