The L3 is an Audio Control Center that is second to none.  The L3 has inputs and switching optimized for CD, DVD, Tuner, External Phono, Video, AUX and conventional Tape. To keep signal paths as short as possible, selector switches use special cross-chassis axles to bring switching functions closer to the delicate audio circuitry thus minimizing distortion and crosstalk. The L3 features a Dedicated Outboard Power Supply to keep unwanted AC fields from the main chassis. Volume and muting functions are operated from the front panel or by Remote Control. The L-R Balance Controls are Precision Stepped Attenuators.
This preamplifier retains all the fine features of its predecessor but with improved active, unity-gain circuitry to accommodate surround-sound processors used in home theater applications. The new L3 also incorporates the improved signal input switching circuitry of the M3B by which each input jack has a dedicated relay that permits a more direct signal path.

Further improvements to the preamp lower the drive impedance of the separate power supplies and improve the stepped attenuator volume controls. The automatic muting circuitry has been refined and the design of our proprietary film capacitors. Redesigning the motherboard has also resulted in improved signal to noise ratio and channel separation.

For many years is has been understood that tube preamplifiers are susceptible to common mode noise. In an effort to further reduce these common mode noises the external power supply was redesigned. The new design utilizes choke input filtering and is fully regulated. The net result of these changes is lower open loop impedances and a virtual elimination of common modes noises. This increases the L-3’s ability to pass complex waveforms resulting in an even more accurate reproduction of music.

Additional enhancements have been made to internally dampen the L-3 and eliminate resonances at the source. The resulting sonics and dynamic contrasts are breathtaking.

For Home Theater use the L3 includes complete input and output switching facilities for external surround-sound processors. Another feature incorporates special active circuitry for optimum matching of components and prevents signal degradation and impedance mismatches.
Special provision has also been made to incorporate Audibles' Optional Plug-in Phono Stage. This discrete circuit, designed with advanced JFET technology, gives new meaning to vinyl playback.
