Unique audio products made to preserve the life and emotion of music.

Innovative design, materials and construction provide a listening experience like no other.

Hand made in Chicago, USA for a lifetime of musical enjoyment.


Simple circuits minimize the number of components in the signal path.  Parts are made with precision from the highest purity materials for the least influence on the audio signal.  This minimalist approach is mirrored in the clean design and operation of the products. 

Low noise power supplies isolate the audio signal from interference.  Optimal operating points are maintained to minimize distortion and provide long term stability. Exacting circuit board layout allows short signal paths, small current loops, and minimal noise. 

Unconventional in construction.  Unique in size, design and appearance.  Uncompromising attention to the smallest details like no other product.
