Stereo Power Amplifier
The MA-380 is a 2 channel stereo power amplifier with the use of 12 carefully selected and matched Bipolar Power Transistors (3 paris per channel, 6 pairs in total). With a rated output power of 150 watts per channel at 8 ohms (300 watts per channel at 4 ohms), the MA-380 is capable of driving any loudspeakers even with low efficiency and low impedance.

Each of the MA-380 power amplifier is handcrafted with the use of highest quality parts and components. The audio grade toroidal transformer is custom wound according to our specifications. Even the heavy-duty special designed heat sinks are custom made in order to meet our standards.
