This project has been in the works for quite a while. It uses the circuit I have been dreaming about for more than a decade. Loosely speaking, the circuit is based on the 1934 Western Electric Model 91, but the front end has been modified to take a line-level input direct from an iPod if you wish. This blending of cutting edge miniature technology coupled with such antique circuitry makes me roll around on the floor with joy.

Many audiophiles maintain that this is the most linear audio circuit ever. Each monoblock puts out around 10 watts and weighs close to 60 pounds. I decided to go “all the way” with details like the engine-turned sub panels that the tube sockets mount on to. This lends a nice visual contrast and provides excellent convection ventilation for the circuit.

These amps are formidable structures and their additional expense and size (compared to my Single-ended Stereo Amp) puts them in a league of their own. However, I have never heard anything so sweet. These amps also pair beautifully with our Little Horn Speakers.
