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.
