Description: The MOSFET outputs are acknowledged worldwide for their ability to amplify harmonics, musical texture, and extended bass with unequaled accuracy. The circuit design with a larger and quieter toroid power transformer and oversized power supply capacitors, deliver the large amounts of current demanded by low impedance speaker loads.

The pure simplicity of the design helps to keep the damping factor high to maximize speaker control... read more
