The preamplifier Heritage is the newest product of Orpheus. Indeed, the topology is always dual mono meaning that the power supply of the right and left side are completely separated. Moreover, the electronics has been revised so that the PSU can provide more power to the output while minimizing the temperature drift. The left, right and digital grounds are connected only in a single point. The power supply is physically separated from the rest of the audio system to reduce the disturbances induced by transformers and diodes used to rectify the alternative current. The total power supplied by the transformers reach 350 [VA].
The windings for digital and analog voltages are completely separated. Each side has a capacitance reservoir greater than 55[mF] to properly rectify the voltage and limit its ripple noise. A ground connector is present on the rear of the PSU to connect all grounds together if necessary.
