Description :
The Proceed AMP2 is designed by Madrigal Audio Laboratories, Inc. which also builds the famous and high-end Mark Levinson equipment. The amplifier has several design features which are responsible for its outstanding performance. It has a dual mono design with each audio channel having its own dedicated power supply which includes a separate 300VA toroidal transformer each. This approach reduces crosstalk between audio channels for superior imaging and reproduction of acoustic space. The demands placed on one channel have virtually no effect on the performance of the other channel. The AMP2 has a low power supply impedance which is a critical factor in the ultimate performance of an amplifier. When the music gets demanding, the amplifier requires much more power and the impedance level drops. Having a low power supply impedance means the amplifier will be able to access to the power it needs, when it needs it. This yields an optimal environment in which the amplifier may operate to its maximum potential. The amplifier is also equipped with XLR inputs which allows the user to take full advantage of greater immunity from noise, RFI, and EMI. The Proceed amplifier has extensive protection to prevent damage to the amplifier when there is a fault. It will shut itself down if it senses either the presence of DC (direct current) leakage at the output or an unsafe operating temperature. In addition, the AC input to each transformer is fused to protect against excessive current conditions such as driving shorted outputs. Finally, inrush limiting prevents premature aging of power supply components during power-up, and switches off-line once the power supply has been charged.
When paired with the Proceed Pre, the accompanying literature of the Proceed AMP2 promises power with finesse and control. The power handling capacity of the combo is quite astounding. Soundstaging, upper-end treble, lower bass and volume mark their presence with an unmistakably lively, airy feel to the music. This combo does a remarkable job with the different forms of music. The soundstaging is just about right, a comfortable area between in-your-face upfront and back-of-the-barn laidback. When digging deeper into the sonic qualities, the Proceeds do have the ever-so-slightest niggle. They are fast as well as musical, but the balance is slighty skewed to the speed factor. This may show up in harsh speakers as a hard-edged glint. The Proceed AMP2 is a powerful, versatile and extraordinary power amplifier, which is also certified for use in Home THX audio systems. It is equally suited to the rigors of film soundtracks and finesse of high end music reproduction. In today's growing market for multi-purpose systems, the Proceed AMP2 power amplifier represents a remarkable value.
