The most important legacy of Conrad-Johnson design's beginnings is the basic methodology which took shape in the course of the development of that first preamplifier. This methodology has enabled Conrad and Johnson to develop new products which have routinely been ranked among the most musically satisfying. Few other manufacturers have so consistently received such high praise for their products.

Each Conrad-Johnson amplifier is patiently and carefully hand assembled, then individually inspected and its performance verified by an experienced audio technician.
