The new VAC ($150.000) 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. 

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 and adjustable loading. Power supply arrangements are dual mono throughout, with six main power transformers for left & right power amplifier, line stage, and phono stage.

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. 
The Statement 450i iQ goes on sale on October 2. MSRP has been established at $150,000. 
VAC is an internationally known manufacturer of the finest high-end audio components. It was established in 1990 in Sarasota, Florida, where it maintains its offices and manufacturing facilities. 
VAC / Valve Amplification Company will introduce the latest member of its award-winning family of Statement audio components at the 2018 Rocky Mountain Audio Fest in Denver, CO, October 5-7.
