The power of the new monoblocks is more than 1 kilowatt per channel, and a 1,000 VA toroidal transformer and 40,000 microfarad filter capacitors are installed in the power supply of each amplifier. The upper panel is made of glass and reveals the internal structure of the device to those who wish. A pair of monoblocks weighs 85 kilograms, and 24 manually selected transistors work in the output stage.
The AVM MA 6.3 mono amplifier concept is well known for the award-winning "8" power amplifiers. With a high output power of 680 watts per channel, the MA 6.3 features a compact OVATION enclosure equipped with external radiators. The MA 6.3 is designed as a balanced Class A/AB amplifier, which has output stages on MOS-FET transistors. These MOSFET transistors are inherently much faster than bipolar transistors, but they are much more difficult to handle. The speed of this MOS FET-based circuit helps realize an unprecedented level of tonal detail.
