Design:
Class A amplifiers with 1.2 metres of heatsink radiating area! Balanced or unbalanced inputs (switched via an input selector on the rear), designed to be used with The Alchemist Pre pre-amplifier. Sold in pairs for stereo. Independent 4, 8 or 16 ohm load speaker outputs connections are provided and these are doubled-up for easy biwiring. If connected correctly with other models in the "The" range, activating The Pre amplifier sends a voltage trigger to the others so that they switch on and off at the same time.
Original selling price: 10,000/pair
