The Bellari VP530 is a USB/Tube phono preamp for use with moving magnet and high output moving coil cartridges.
It includes a built in headphone amplifier, Burr-Brown analog to digital (A2D) converter with USB output, and RIAA curve/flat EQ.
The vp530 is designed to amplify an RIAA equalized phono signal to a high level signal or provide a usb digital output. Since the unit utilizes tube circuitry, the resulting output signal is warmer and more musical than solid state preamplifiers. The real kicker, aside from the price and stellar sound, is that it's manufactured in the USA.
