For some audiophiles only a Single Ended design amplifier (only one output valve) can reproduce that "Holy Grail" of musical performance which in reality is rarely achieved. The 805 valve offers the potential to give a large amount of power to drive conventional speakers with ease, but this unique transmitting valve is difficult to drive. Icon Audio use a small power amplifier in the form of a 2A3 triode which is itself driven by 4 6SL7s to the right dynamics and sympathetic feel.
