This amplifier gets you into serious listening without breaking the bank. The SA103 are often sold as monoblocks and if you want to do that, and you have time to organise it, the factory can ensure they are made consecutively.

Plinius' distinctive heatsink profile has allowed us to maintain the classic look and produce an amplifier capable of operating in Class A without the use of troublesome fans or other methods used for cooling. Its 500mm by 455mm footprint belies the power it produces and these units sit comfortably beside big speakers, understating somewhat their contribution to the speakers' performance.

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.

These units are at the top of the Plinius range, sitting right under the SA Reference amplifier. With responsiveness and control they faithfully support your speakers as they seek to replicate the original artists' efforts for your listening pleasure.
