Tangent Power Ampster II
Compact stereo power amplifier in Class D, with stereo or bridge mode and RCA/XLR inputs, to drive a wide range of speakers.
Description
The Power Ampster II is a stereo power amplifier from Tangent, designed in Class D to offer high efficiency in a compact format. Its role is to provide the power needed for passive speakers, complementing a source or a preamplifier, without taking up the space of a traditional amplifier.
It delivers 2 x 100 W into 4 ohms in stereo mode, or 1 x 200 W into 8 ohms when used in bridge mode to power a single pair of speakers with greater power available. Its frequency response extends from 20 Hz to 50 kHz, covering most of the audible spectrum, while its signal-to-noise ratio of 85 dB ensures a clean reproduction, with no perceptible hiss during everyday listening. The metal chassis and modest weight of 2 kg reflect the compactness sought for this type of device.
This model is aimed at those wishing to add or replace a power stage within an existing setup, without adding bulk: multiroom system, compact configuration paired with a DAC or preamplifier, or a project requiring a discreet amplifier capable of fully driving power-hungry speakers.

What to check before buying used
With this type of Class D amplifier, the main point to check is the proper operation of the output stages and the absence of unwanted noise or dropouts at higher volume. Also check the condition of the screw-type speaker terminals, which can loosen or wear over time, as well as the behaviour of the automatic standby function, which should engage smoothly in the absence of a signal.
