RARE!!! High-End PROCEED PRE Preamplifier (Madrigal Labs/Mark Levinson)
Made in the USA
To achieve the finest performance, music systems require a high
quality preamplifier. The preamp serves multiple purposes: it must
serve as an electronic buffer between the output of the source
components (CD players, tape decks, DAC's, etc.) and the input of the
power amplifier; it must transparently select the sources to be listened
to and/or recorded; and, most obviously, it must provide essential
functions such as volume control. Madrigal Audio Laboratories makes the
ultra-high-end Mark Levinson two-channel audio equipment and made the
Proceed lines of high-end home theatre products. This preamplifier is
elegantly designed with superb build quality manufactured in Middletown,
CT by the people of Madrigal Audio Laboratories.
The foundation of any electronic design lies in the quality of its
power supply. The PRE provides exceptionally clean, stabel power to all
circuitry, thanks to its low noise toroidal transformer and multiple
stages of power supply regulation. Two balanced inputs using precision
XLR connectors take advantage of today's highest quality source
components. Properly implemented, balanced connections provide superior
immunity from noise and offer a more open, dynamic sound. For these
reasons balanced outputs are also provided on the PRE for passing the
signal along to the power amplifiers that follow. A set of single-ended
outputs ensures compatibility with power amplifiers which lack balanced
Accurate volume control in a stereo system is crucial. Without it,
aural images wander from their intended locations and ambient
information cannot support the recreation of the event as it should.
The PRE uses monolithic, laser-trimmed attenuators that match channels
to one another to better than one part in one thousand, resulting in
unsurpassed realism in a reproduced soundfield. Increments of one-half a
decibel allow precise volume and balance adjustments.
Last but really cool! The PRE allows you to bypass the main L/R
channels from 2-channel stereo to go to the main L/R of your surround
receiver for home theater use, giving you the best of both worlds!
