Graham Slee Solo Ultralinear DE Headphone Amplifier
Whilst other headphone amplifiers follow a one-way trend, the Solo Ultra Linear headphone amplifier is original thinking. It's far less coloured - if it can be called coloured at all - it reproduces music so precisely it naturally sounds musical!
The Solo Ultra Linear headphone amplifier lets the music flow - it's timing is second to none. The bass is full but never loses control. The highs are free of grain and harshness. Stereo imaging is the best it can be without artificial cross-mix or width extension. Made for the best signal sources - the Solo Ultra-Linear headphone amplifier will be your best headphone amplifier purchase yet.
The Solo Ultra Linear headphone amplifier is a J-FET input - discrete transistor output-stage design which uses open-loop gain and bandwidth modified operational amplifiers that mimic valve/tube performance. The result is linearity in all areas that can only normally be provided by valves/tubes. However, the Solo Ultra-Linear headphone amplifier can directly drive low impedance headphones - as low as 5 Ohms - as well as high impedance headphones.
It also includes our proprietary headphone load feedback network which cancels much of the Solo Ultra-Linear current drive output impedance as well as controlling headphone cable capacitance and inductance so you should never need a cable swap to hear your headphones at their best.
