LC audio Millennium User Manual

The End
Millennium
The End Millennium is a high quality Power Amplifier, in power sizes of 99 to 300 Watts (8 Ohms).
While running in Class A/B the high sound quality is reached through a number of advanced
design strategies. First of all no feedback loops is found in the circuit, as any error that might be
corrected by the feedback loop, cannot be corrected before it is factual, and then - obviously - it
is too late. A simple circuit topology with a minimum of high quality components ensures short signal
path. Poly prop Capacitors, Vertical bipolar multi emitter transistors, glass substrate resistors to
mention some of the high-tech components used.
The higher frequencies are played with simplicity through the ultra fast amplifier (linear to >500.000Hz)
and the four stage output power tunnel gives a firm and fast bass reproduction. The total soundstage
is well controlled and well defined, with precise space and nerve visuality.
