5A-103 Power Amplifier


1989 saw the introduction of the PLINIUS SA-100, developed as a stereo breitling imitacion amplifier from early work done by the PLINIUS design team. The SA-100 broke new ground in that a powerful Pure breitling replique montre Class A amplifier was available within an economic package. Many hundreds were sold under different guises, culminating in the SA-102 in 2003.

Time passes, development continues and with the introduction of the SA-Reference amplifier a new standard has been achieved for PLINIUS.

The PLINIUS SA-103 has been developed on the heels of the newer PLINIUS amplifiers and it shares the sonic and aesthetic gains that have elevated these designs to new levels.

The classic PLINIUS look has been maintained with the use of the distinctive heatsink profile that has allowed us to produce an amplifier capable of operating in Pure Class A up to 125 watts per kopior omega channel without the use of troublesome fans or other methods used for cooling.

Balanced circuits used in the SA-103 allow full Balanced Mono operation in excess of 400 watts. The addition of another SA-103 will provide an amplification system capable of the highest level of excellence without totally breaking the bank.

As with all PLINIUS amplifiers,premium components have been used throughout. There is the addition of a 12 Volt trigger which will allow integration into a semi automated system.

Sonically the SA-103 embodies all that we have learned and will paint a very believable and transparent facsimile of a live musical event.

A small group of dedicated technicians build each SA-103 by hand in our New Zealand factory ensuring that our stringent standards are maintained.
