It takes all the good points of tubes, but won't wear out like tubes, and drives low impedance headphones too! In fact it will drive headphones of 5 Ohms impedance upwards with ease. The new Graham Slee Solo Ultra-Linear Diamond Edition gives you everything you ever wanted in headphone sound quality!
What's more it's tough and reliable made by the best British engineers not offshore operatives like so much of the competition use.
Its 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.
Its all-new output stage supplies the drive demanded by difficult and low impedance headphones.
Its vastly reduced hiss levels make listening to ultra-sensitive earphones a pleasure.
And like all of Graham Slee's headphone amps it protects your expensive headphones from DC offsets which could otherwise burn them out.
At last the headphone world has a headphone amplifier capable of making all headphones deliver a truly lifelike dynamic and breathtaking performance with a real out of head 3D stereo sound stage with capable headphones.
Make the Solo Ultra-Linear Diamond Edition your reference - the foundation on which to upgrade your source equipment.
The Solo Ultra-Linear Diamond Edition builds on the success of the Solo Ultra-Linear, itself being highly acclaimed by all its users as a breakthrough headphone amplifier, and one of the biggest selling headphone amplifiers in the world today.
