The Sapphire LPA-800 Line Pre-amplifier is based on the wonderful DAP-800 but without the digital element.  There are still six analogue inputs including one bypass input as well as one balanced input and one balanced output.  

The pre amplifiers analogue stage incorporates a Sugden VCV circuit in its most advanced form.  This circuit has a high impedance input section, current gain stage which drives a folded cascode stage into a Class A output stage. The folded cascode circuit facilitates a wide bandwidth with maximum dynamics and low capacitive connectivity. This delivers a sophisticated sound that is neutral and transparent.
