The Marantz AV7005 preamplifier/proc essor proves beyond any doubt that less is more. No, you won't find an amplifier inside its rugged chassis. Instead, you'll find performance standards well beyond those expected by even the most demanding home theater connoisseur. Carefully designed circuit boards take full advantage of a preamp/processor' s superior thermal environment. Both balanced and single-ended outputs mean you can select the amplifiers that best fit your needs. The AV7005 brings you the flexibility and connectivity you need to enjoy all the sources today's A/V world makes possible. Delegating the amplification duties to a separate component allows the AV7005 to keep a healthy distance between noise-inducing high voltage/high current circuits and sensitive low-level circuits...

With zone mode switch set in the Bridge Mono position, both channels in the zone are combined for a mono output of 140 watts into an 8-ohm load. All this power is supplied by three high-output toroidal transformers. Each amplifier output... Less

The idea that "One Size Fits All" may sound good in theory, but in practice it usually leads to "One Size Fits None". While most manufacturers assume that the few amplifiers they offer are good enough to work in all situations, the truth is that they usually fall short of meeting your multiroom audio needs, especially in complex applications. Even if you have a basic system, you may require more advanced features in the future. In these times of rapidly advancing technology, many of us have found that the products we purchase today are outdated tomorrow. SpeakerCraft has strived to reduce this problem by building one of the most flexible and advanced amplifier lines on the market today. The Big Bang series of amplifiers is a highly reliable line that offers a solution for every... Less
