Audible Illusions Modulus L1


The Audible Illusions Modulus L1 is a line stage and headphone amplifier that features the advanced sonics and impeccable build quality of the Modulus Three.

For those listeners without turntables or LP collections, or who choose to use a high quality offboard phono pre-amplifier, the L1 has, instead of a phono section, an ultra high quality headphone amplifier.

This discrete solid-state circuit, featuring dual monolithic FETs and ultra fast ring-emitter transistors, is capable of a full 7 to 10 watts of output.

This is not an afterthought or add-on circuit but an innovative design made to drive the most sophisticated headphones on the market and to rival the sound of the best amplifier/speaker combinations.

At last, headphone listening need not be relegated to mass market status, the better your headphones are, the more you will reveal the L1's virtues.

In terms of features, the Modulus L1 is an audio control centre second to none.
