Statement 450i iQ
Integrated Amplifier

The Statement 450i iQ Integrated Amplifier is an ultimate performance, cost-no-object instrument that establishes a new benchmark for sound quality in integrated amplifiers. Part of the secret of its performance is in the unusual vertical form factor, which allows the optimal placement of circuit elements and purest, most direct routing of signals, for a total result that exceeds the sum of its parts.

Statement 450i iQ
  • The Statement 450i iQ builds upon the prior art of the Statement separate components. Conceptually the 450i includes a Statement 450S iQ power amplifier, a Statement Line Stage, and phono stage with multiple inputs, variable gain, and adjustable loading. Power supply arrangements are dual mono throughout, with six main power transformers for left and right power amplifier, left and right line stage, and left and rght phono stage. The internal topology is fully balanced.

    VAC’s patented iQ Continuous Stable Automatic Bias System* keeps the KT88 output tubes set at the intended operating point at all times for better sound, protection, and automatic indication of when tubes should be replaced.

    When you listen to the VAC Statement 450i iQ you quickly will understand why others describe the experience using words like amazed, transfixed, flawless, and stunning.

    To protect your investment, your Statement 450i iQ will come to you in a custom flight case. The case is on wheels for easy placement, and is made in three sections which allow it to be unpacked without ever having to lift the full weight of the amplifier. The amplifier tower is supported by four integral captive roller balls that allow the unit to be moved, yet supply good mechanical grounding and support.

    * The VAC iQ Intelligent Continuous Automatic Bias System is protected by U.S. patent number 8,749,310, worldwide patents pending.

    “In short, its combination of timbral accuracy, transparency, transient fidelity, and bass authority have endowed the VAC Statement 450i iQ with the most genuinely musical voice I have yet heard.”
