This amplifier will deliver more than 2000 volt-amps per channel into an ESL, and when driving magnetic speakers, the ESL amplifier will deliver over 360 watts/channel into an 8 ohm load, into a 2 ohm load exceeds 1000 watts.

Features 

  

 

 

  • The quality of construction is typical of the finest components made today.

  • Resistors are high reliability, precision metal film, 1% tolerance.

  •  

  • Capacitors are of the highest quality and none are used in the signal path.

  •  

  • Connectors are either gold or rhodium plated.

  •  

  • Both balanced and single-ended connectors are standard.

  •  

  • Available with either black or silver face plate

  •  

  • There is no wire in the signal path save for a 2-inch piece connecting the circuit board to the output terminal.

  •  

  • The amplifier runs very cool.

  • The amplifier is completely modular for easy servicing or upgrading.

  •  

  • The amplifier is completely stable and will not be damaged even when driving a 1 ohm load.

  •  

  • The finest quality, WBT binding posts are used. These are widely spaced and positioned at a 45 degree angle for ease of use and speaker cable  routing.

  •  

  • The amplifier uses so little power at idle that it can be left on continually for optimum performance and longest life without concern for power usage or taxing your room's air conditioning system.

  •  

  • A massive output stage using 18 transistors makes the amplifier extremely rugged and reliable. It will drive the most difficult (low impedance and reactive) loads without strain or damage, which is why it is ideal for driving electrostatic loudspeakers.  

  •  

  • Although called the "ESL amplifier", the same features that make it ideal for driving difficult electrostatic loads also make it ideal for conventional, magnetic loudspeakers, which are easier to drive. It is not limited only to electrostatic speakers. It is particularly good at driving planar magnetic speakers that have a very low impedance and require powerful amplifiers.

  •  

  • The mains voltage is user-selectable from the rear panel, so the amplifier can be used anywhere without having to be modified at the factory for different voltages.
