Overview | Specifications


Many audiophiles remember how the introduction of the original Modulus preamplifier excited the audio industry. For the first time a full-function, reliable vacuum tube preamp with true high-end sound was available at an affordable price. It’s rare for a company to capture ones imagination and loyalty even once in such a manner. With the debut of the new L3B Line Stage the Legend Continues.

As many audiophiles migrated to CD and digital media for their main source we began producing our Modulus line stage series. These preamps were specifically designed to optimize digital playback and other line-level equipment. While the L3B retains the physical characteristics of its predecessors, it‘s not a rehashing of old ideas. The preamp is on the leading edge of audio technology. The L3B makes elegant use of engineering approaches to circuit board design that improves signal flow and reduce interference and vibration. A Class A, zero feedback, single-ended design built on the proven tube design philosophy that “simpler is better”. Additional improvements include dedicated relay signal switching and Teflon coupling capacitors which result in outstanding resolution. The L3B also features a dedicated external power supply which isolates AC fields from the main chassis and prohibits common-mode noise from interfering with the musical waveform.

In terms of features the L3B is an audio control center second to none. It has inputs and switching designed for CD, DVD, Tuner, External Phono Stage, Video, Aux and Tape. Volume and Muting functions are operated from the front panel or with Remote Control. The L-R Balance Controls are Precision Stepped Attenuators.

For Home Theater use the L3B includes complete input and output switching facilities for Surround Sound Processors. Another feature incorporates special active buffer circuitry for optimum matching of components which prevents signal degradation and impedance mismatches.

As with the previous Modulus preamplifiers, the L3B is next step in the evolution of our famous single-ended designs. The Heart of Fine Audio and Video Systems for Years to Come.
