The Balanced Audio Technology VK-500 sets a bold new standard for solid-state power amplifiers. The VK-500 combines the benefits of high-power fully balanced operation with a simple, direct signal path to yield a level of musicality traditionally reserved for the world's finest tube amplifiers. Yet it offers a dynamic ease that few designs - tube or solid-state - can match.
The solid-state virtues of extended frequency response and the power to drive inefficient speakers are often purchased at the price of a clinical or fatiguing presentation of the music. The problem lies more in the complexity of most solid-state circuits than in the devices themselves. A typical solid-state amplifier will have four or five gain stages, with a feedback loop traversing these same stages to correct the signal. The VK-500 uses only two gain stages--without global feedback. Unusually direct for any amplifier, this purist signal path is even more surprising in a design of such high power. The ingenuity of the signal path is complemented by a unique single-ended bridge topology to allow the use of superior N-channel MOSFETs in both driver and output stages. The result is a clear, open sound that breathes life into music.
The VK-500 delivers 250 watts per channel of effortless power. It can also be ordered with an optional BAT-PAK® joule multiplier. The BAT-PAK provides an internally installed capacitor bank that triples the energy storage of the VK-500. In addition, the VK-500 can be converted at the factory to Balanced Audio Technology's VK-1000 monoblock, providing an upgrade path to even greater power.
The VK-500 is constructed as two individual amplifiers on one frame to capture many of the benefits of monoblock construction while maintaining the convenience of a single chassis. This dual-mono construction extends to separate power cords, power switches, transformers, and circuit modules. The VK-500 could be cut down the middle with an acetylene torch and both halves would still play.
The performance of Balanced Audio Technology's VK-500 transcends the limitations of traditional solid-state designs. It couples effortless dynamics with a supremely natural portrayal of musical color and texture. We invite you to visit your BAT audio specialist to experience this revelation for yourself.
