The
Vanguards amplifier incorporates a massive power
supply with a 750 VA toroidal transformer and 80,000
microfarads of storage capacitance. The tremendous amount
of energy on tap provides 200 watts per channel into 8 ohms
and 400 watts into 4 ohms. Two quiet, thermostatically
controlled fans permit the use of a surprisingly compact
chassis. The preamplifier section of the Vanguard borrows its
balanced, fully discrete Class A circuit concepts from Krells
top-of-the-line Illusion preamplifiers. Krells 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. Packed with many of Krells most musical-sounding
technologies, the elegant chassis is living-room-friendly. Yet
it has enough power to achieve incredible, lifelike dynamics
with any speaker. The front-panel menu system provides configuration features
such as input naming and input trim. Theater Throughput
mode lets the Vanguard serve as the core of a surround-
sound system without sacrificing two-channel sound quality.
Analog Inputs include three stereo RCA and one stereo
balanced XLR. High-quality WBT speaker cable terminals
provide a secure, electrically ideal connection.
The Vanguard also offers features that make it perfect for
custom installation, such as 3.5mm jacks for IR input and 12-
volt trigger input and output, as well as optional rack-mount
ears. Additionally, the unit can be controlled with home
automation systems through its Ethernet connection.
A key
option for the Vanguard is the digital module, which
includes USB, HDMI inputs and output, coax and optical
digital inputs; Ethernet music streaming controlled through
dedicated iOS and Android apps:
