Graham Slee Solo Ultra Linear Diamond Edition Headphone Amplifier (Includes PSU1 Power Supply)

The new Solo Ultra-Linear Diamond Edition hi-fi headphone amplifier gives you the sound you always wanted from a headphone amp! A headphone amplifier truly capable of making good headphones deliver a lifelike, dynamic and breathtaking performance with a real out of head three-dimensional stereo sound stage.

The Ultra-Linear voltage amplifier stage gives you the smoothness and warmth of a tube amp, yet with all the precision, fine detail, and punchy sound of the solid state amp it is. Plus, it won't wear out like tubes.

Make the Solo Ultra-Linear Diamond Edition your reference!

 


Features

Ultra-low noise:the Solo Ultra-Linear Diamond Edition is now also ultra-low noise as well as being ultra-linear.

Higher output current: its output stage has been beefed-up to take control of the most difficult headphones with ease.

No dangerous DC on the headphone output prevents headphone damage: it only takes a small amount of DC offset to heat up the windings of headphone transducers. That heat softens the adhesive which keeps the "voice-coils" in place, and eventually your headphones don't perform all that well. All our headphone amplifiers block DC offset from reaching your headphones.

Tape monitoring: the Solo Ultra-Linear Diamond Edition headphone amplifier has two inputs and a non-shorting mute. Its input switching can be used in tape monitoring as shown here.

(An extra pair of interconnects are required as well as two phono tee-adapters inserted where indicated by the asterisks shown in the diagram)

When connected as per this suggestion, the input selector on the Solo front panel mimics a tape monitor switch. In position 1, the same source as selected on the amplifier is fed to the Solo; in position 2, the output from the tape recorder (or other recording device) is fed to the Solo.

Headphone sensitivity volume control: unlike conventional volume controls, this one is designed to be used over its full rotation to compensate for a wide range of headphone impedances and sensitivities. This avoids the use of gain switches which would otherwise result in differing performance characteristics depending on the gain setting.
