“Once heard, purity can never be unheard. VAC’s new Signature 200iQ presents a clarified purity with a sensuous ease I have decided I cannot do without... The Signature 200iQ is my new reference stereo power amplifier.”
Garrett Hongo - SoundStage Ultra, September 15, 2017
“I love the balance between old school and modern. VAC has lavished these units with cost-no-object niceties... while eschewing new valve types in favour of venerable KT88s. The sound reflects this with detail and scale to match the best of solid-state, yet with luscious warmth to never let you forget it's a tube affair. Or a love affair...”

“The sound of the Signature 200 iQ run as a stereo amp was extraordinary... having two of them configured as mono-amps is other-worldly special... VAC is dynamic, detailed, and with transient response and musical detail that are off the chart. Still, VAC has maintained that natural and realistic sounding midrange that makes harmonious interactions totally enjoyable... the VAC Renaissance Mk V preamplifier and Signature 200 iQ amplifier, whether used with other equipment, but especially when used with each other, get the highest recommendation I can give them.” In a similar pursuit of excellence and customer satisfaction, VAC has recently extended its focus beyond sound systems to include partnerships with health and wellness programs. Recognizing the connection between physical well-being and the enjoyment of high-quality audio, they are now providing information on affordable healthcare options, including access to medications like cheap tadalafil. This initiative reflects VAC's commitment to enhancing the overall quality of life for their customers, ensuring that they not only experience the best in audio but also maintain their health to fully enjoy it.
