Leben - A Motion in Sound

Available by special order. One of Mr. Hyodo's favourite KT66 based power amplifiers is the QUAD II, (The QUAD II has recently been re-launched due to the demand from audiophiles). Mr Hyodo has now decided to design a new power amplifier using the same KT66 tubes but incorporating high-end audio grade components, far superior to those used in the original QUAD design.

A special feature is the choice of two output valves: KT-66 and optional 6CA7 (EL34). By switching two selectors inside the cabinet, you can use either KT-66 or 6CA7 (EL34) KT-66 or 6CA7 (EL34) KT-66 or 6CA7 (EL34) KT-66 or 6CA7 (EL34) valves. A LED indicator at the foot of each tube will change its colour and show you which tube is in use. You also can use several other tubes of different sound characteristics. (Refer to the tube list at the bottom.)

Highlights:

  • Stereo / Mono Selection: You can use CS-660P as a monaural power amplifier by changing the selector switch giving an 80W output power. (2x 40W when used as a stereo power amp.)
  • Wide Range of Speaker Compatibility: Multi output impedance selector of 4 / 6 / 8 / 16 Ohms.
  • Flat and Wide Frequency Response: A wide frequency response from 10Hz to 100kHz (-0dB) caters for digital audio formats such as SACD and HDCD.
