VAC Statement 450 iQ Monoblock Power Amplifier

VAC Statement 450 iQ Monoblock Power Amplifier

The Statement iQ power amplifier is the first in a series of VAC components featuring the new VAC iQ Intelligent Continuous Automatic Bias System (patented*). The VAC iQ System builds on the unprecedented performance of the original Statement Series and takes it to a whole new level with a set of critical enhancements.

The VAC iQ System is the result of 18 years of research and development by the engineers at VAC, and represents the first time in history that each tube in the output stage of a vacuum tube amplifier can be held precisely at the optimal bias point (underlying true quiescent current) at all times, regardless of how loudly or softly the music is playing. The result is sound that is always the best it can be, reduced distortion and noise, longer tube life, elimination of gas current ‘run away’ tubes, and increased reliability, all without any effort by the user.

The VAC iQ System also alerts you when a tube is growing weak or has failed. In short, tube drama is a thing of the past.

The Statement iQ power amp also features newly improved output transformers (56 pounds per monoblock!) with smoother, more extended frequency response. Input signal handling has been changed to a more pure, direct connection. Various changes to the power supply and chassis materials compliment and support the iQ system and circuit refinements.
