Yosemite PreamplifierOur first tube preamplifier build began as many ampsandsound products do, inspired by icons. In this case, legendary line phono units like the C22 and Marantz Model 7 guided the basic approach to the circuit. Many of these units provide controls largely abandoned by the modern audiophile tone controls for example. These add not only additional parts, but require additional feedback to compensate for their effects, a design compromise that runs counter

The XLR inputs us an input transformer to convert the incoming balanced signal to a single ended signal for the amplifier

which most consider the standard-bearer for tube amplifier builds

The return of the Hudson marks ampsandsound’s pivot back to our roots

Compatible with nearly every headphone

This approach lowers the noise floor

and rich detail in a design that will appeal to audiophiles who desire all of the positive attributes of horn-loaded designs

The Black Pearl XL incorporates this tube in a circuit rooted in designs by Western Electric and refined by RCA
