GRAHAM SLEE - Graham Slee's Solo Ultra Linear Headphone Amplifier with PSU1

  • A headphone amplifier with an ideal balance of valvey smoothness with detailed clarity, and full frequency extension with "effortless" dynamics, makes the (solid state) Solo Ultra Linear Diamond Edition headphone amplifier a must-have companion for late night and personal headphone listening at home.

    The Diamond Edition Solo Ultra Linear headphone amplifier has a lower noise floor for improved in-ear monitor listening and a new output stage for better performance with difficult and low impedance headphones, yet it has the clout to drive high impedance headphones too.

    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.

    If you have a Solo SRGII from mid-2004 onwards, you can upgrade to Ultra Linear Diamond Edition performance, with either our factory upgrade, or easy do-it-yourself upgrade. For full ULDE performance, don't forget to use the PSU1 linear power supply.
