Hagerman Audio Labs Delivers an Aesthetic Upgrade to Popular Phono Products
looks matter
Hagerman Audio Labs recently announced aesthetic upgrades to a number of its most popular and popularly priced products including the $589 Cornet MM vacuum tube phono preamplifier pictured above, now upgraded into a metal chassis with optional available wood side panels.

The circuit topology features common cathode class-A gain stages with no feedback, passive equalization, and cathode follower output buffers with constant current sink loading. Power is supplied by a regulated wall-wart driving a boost converter (running at about 50kHz) generating the high voltage rail required for proper tube biasing.
The Piccolo head amp ($289) for moving coil cartridges, formerly housed in a plastic case, now also comes housed in a metal chassis. The active circuitry uses low noise matched discrete JFETs in a no-feedback gain and buffer configuration. Both loading and gain are adjustable, providing extreme flexibility.
Over the years we've reviewed the uglier versions of these products.
