Plinius SA-103

220 watts of pure Class A power into 4 ohms with 400 watts into 8 ohms mono output. This is a world class, solid state amplifier at any price point. The Plinius SA-103 is very musical and detailed, with great rhythm and pace. It has a balanced, natural sound with a phenomenal build quality. Weighing in at 83 pounds, this is an impressive piece of equipment.

The Plinius SA-103 has not received the recognition it deserves. Martin Logan and Magnepan owners really need to audition this amplifier. The Plinius SA-103 is a perfect match for the Magico S5 and S1 speakers. We are really impressed with this combination. The Plinius SA-103 is a one of the best solid state amplifiers on the market at any price.
