The 2.2 XP is designed to run seamlessly with the award-winning 2150 line of amplifiers.

When the 2.2 XP is used in connection with TacT true digital amplifiers it can control the volume level in the power amplifier via the RS 232 cable. When the volume control of the 2.2 XP is used, the actual level in the 2.2 XP stays at maximum while control signals are sent to the power amplifier to reduce the voltage level. In this way, the system maintains full 24-Bit resolution and very high signal-to-noise even at very low listening levels. In effect, the TacT combination is the first system that maintains exactly the same resolution at maximum output and at normal listening levels.
