Wisdom Audio SA-3 Power Amplifier

$6,300.00

While many contemporary amplifiers waste 50% or more of the power they pull from the wall as heat, the SA-3 amplifier runs at approximately 90% efficiency. As a result, more power is available for the loudspeaker, and less is wasted as heat in your room.

The high efficiency of the SA-series design also means that the amplifiers can be placed near each other, as in an equipment rack, without undue overheating.
