The Virtus I2 is a new-generation tube amplifier that utilizes KT88 high-power tubes and features an entirely new topology.
The goal of its development was to enhance the superior sound quality of the previous model version. This amplifier runs in a pure class A with an auto-bias function, as well as cathode feedback.
 
Highlights
Operates in a pure class A with an auto-bias
Instant switching between a triode and ultra-linear modes
Possibility to create a monoblock setup of two units.
 
Product Features
an integrated tube amplifier operating in class A, providing an output power of 2 x 40 W
KT88 high-power tubes with autobias with a cathode feedback
an option to switch between triode and ultra-linear mode instantly
PCB’s utilize our premium CMT ™ technology
perfect channel separation using a relay attenuator that features individual blocks for each channel. The gain control is in increments of 1 dB and attenuates up to 63 dB
the independently powered control part
capacitors with high capacitance in the filter provide energy for precise and well-defined bass
the signal path exclusively contains high-quality polypropylene capacitors
precise selection and pairing of the tubes meeting above-average parameters
the synchronous control option allows the use of two amplifiers in a monoblock mode without the need for an extra preamplifier. This Master/Slave mode has an output power of 80 W per channel
