The PSA is a stereo version of the PMA mounted in a single pyramid chassis. It gives 100W of output power from a single stereo unit. The PSA provides the same sonic purity and natural transparency as the MPA but in a more compact format. Designed to be used in conjunction with either the PL-L or PL-P pre-amplifiers and is an efficient amplifier with a unique power factor correction system with auto start stop.

AUDIOPHILE’S CHOICES

To achieve ultimate sound and reliability, the selection of every component is critical. This is especially true for the choice of the power transistors. After numerous electrical and subjective tests, the Research and Development team has chosen to use MOSFET transistors from Exicon. They demonstrated the best characteristics among all the specifications we are concerned with.

ERGONOMICS

The PSA features an Auto-detect power-on, it will automatically start upon receiving a signal on the input connectors. It will also turn off after 20 minutes without receiving signal. This is a great feature for a stereo system, and is a tremendous advantage in a multi-channel system
