conrad-johnson into the application of vacuum-tubes to the reproduc-

tion of recorded music. The result is a power amplifier with a remarkable

ability to recreate the dynamics, textures, tonalities, and ambience of

live musical performances. With the Premier 140, we believe that you

selected with a view to maintaining optimal performance over the years.

Our reputation for producing among the industry’s most reliable compo-

nents is a natural consequence of this engineering approach.

Although the Premier 140 has been designed to operate in an intuitively
