YOU WILL RECEIVE: 1 200 Watt Vanguard Integrated Stereo Amplifier The Vanguard incorporates a 200-watt-per channel amplifier and a Class A preamplifier, enclosed in a chassis that borrows its design and construction from the new Krell Foundation preamp/processor, Connect stream player, Illusion preamp and iBias amplifiers. An optional, field-installable digital module with USB, HDMI, coaxial, and optical inputs as well as Ethernet audio and apt-X Bluetooth streaming will also be available. The preamplifier section of the Vanguard borrows its balanced, fully discrete Class A circuit concepts from Krell's top-of-the-line Illusion preamplifiers. Krell's Current Mode technology is employed to assure unequaled signal bandwidth, easily enough to handle the latest high-resolution PCM and DSD audio sources without impacting high-frequency response and detail.

Polk's exclusive dynamic sonic engine design optimizes the midrange driver and the ring radiator tweeter in separate interior chambers for improved transient response, superior imaging and greater horizontal off-axis response. Enhanced, re-engineered ring radiator tweeters extend top-end response for incredible details and realistic imaging. Extended Linear Motion voice coil design helps extend mid- and high-frequency response.
