About the Statement 450 iQ
The VAC Statement 450 iQ is a flagship, two-chassis vacuum-tube monoblock power amplifier from Valve Amplification Company. It delivers 450 W and uses VAC’s patented iQ Intelligent Continuous Automatic Bias system to continuously regulate the output-tube operating point. Its fully balanced operation with XLR input, large custom output transformers (reported by VAC as 56 lb each), separate audio and power-supply chassis, and 2/4/8-ohm transformer output taps are intended for driving demanding loudspeakers. The output stage uses eight KT88 tubes and the amplifier accepts either balanced XLR or single-ended RCA sources.
