Up for sale I have a Plinius SA-103 Class A Stereo Amplifier that was FULLY RESTORED/ UPGRADED in 9/2026. Ready to rock for another 20 years. Rebuilt by Ralph of Plinius Audio Repair (the US distributor/ repair center) for Plinius Audio of New Zealand, located in SOCAL. Receipt shows all work performed. One of the most incredible solid state amps I have EVER heard. Crystal clear, yet sweet, holographic and the most incredible bass of any amp I have owned. These amps are simply musical and a pleasure to listen to for extended sessions. I would describe it as the closest I have heard to a good tube amp with an incredible amount of drive that is well known to be able to drive difficult speakers. These don't pop up often RESTORED for sale for a good reason. If you buy a unit that hasn't been restored, it will need to be restored, my unit was recently done. Original box and power cord included.

"The Plinius SA-103 offers a natural, neutral tonal balance, just the right amount of musicality, superb bass performance, plenty of current to drive the most piggish speakers, functional and tasteful design. This amp has an endless reserve of power. It is, dare I say, a good value at its price, considering its performance. A small group of dedicated 'technicians build each SA103 by hand in the New Zealand factory ensuring that stringent standards are maintained."
