Graham Slee Novo Headphone Amplifier

Each unit is designed by owner/ engineer Graham Slee and then hand constructed by two skilled electronics engineers before being thoroughly tested to check it meets it's specification and is 100% reliable.

Constructed with all discrete components running in class A, the purity of sound and definition  is quite astounding, and completely betters the other contenders at this price point. Capable of driving headphones of impedance ranging from 16 ohms to 600 ohms, it has a very transparent and dynamic musical presentation that will enthral you.

Coming as standard with a plug top power supply, and  can be easily upgraded by choosing the Graham Slee PSU1 power supply for even better refinement and dynamics - see the options drop down menu.
