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 capability.
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!
