Technical Audio Devices (TAD) amplifier
Technical Audio Devices (TAD) was showing off new monoblock power amplifiers to attach to their well-known line of speakers. The M600 amplifiers ($26,500 each) feature a graphite cast iron monoque construction to help eliminate vibration. Though imposing in size (they weigh 198 lbs each!) the TAD amps feature only one stage of voltage gain. The M600 also features a 22lb transformer, custom-built 33,000µF capacitors, and can put out 600W into 4 ohms. They accept only balanced inputs and will be available in February 2010.
