Conrad Johnson
Conrad-Johnson was founded in 1977 by a pair of economists and audiophiles, Dr. William Conrad and Dr. Lewis Johnson.
It started as simple curiosity between friends: If we take elements of one classic vacuum tube system that we like, and elements of another one that we also like, and get rid of the elements we don't, can we make a better preamp ourselves? So they tinkered, and liked what they ended up with, and so did a lot of other folks, and next thing they knew, the tinkerers had become high-end audio leaders. Today Conrad-Johnson continues its tradition of hand-crafting quality amplifiers and preamps at its HQ in Fairfax, Virginia.
