Electrocompaniet AW250-R
Electrocompaniet AW250-R power amplifier, fitted with balanced XLR stereo inputs and outputs, intended for demanding hi-fi systems.
Description
The Electrocompaniet AW250-R is a power amplifier designed to be paired with a preamplifier or a source fitted with a balanced output, within a high-end hi-fi system. It sits downstream of the control electronics to drive the speakers directly.
This amplifier stands out for its fully balanced connection, with a stereo XLR input and a stereo XLR output. This type of connector limits electrical interference over long cable runs, a useful point when the amplifier is installed close to the speakers rather than to the rest of the system. The measured noise level is particularly low: 90 µV over the 400 Hz to 30 kHz band and 100 µV over the 10 Hz to 30 kHz band, reflecting a very unobtrusive noise floor, favourable to the reproduction of the finest nuances of a recording.
With dimensions of 215 x 470 x 288 mm (W x D x H), the AW250-R fits into a hi-fi cabinet or a rack dedicated to audio electronics.
This model is aimed at enthusiasts of accurately reproduced music, who already own a preamplifier or a source fitted with a balanced output and who are looking for a dedicated power stage rather than an integrated amplifier. It suits a stereo system designed for attentive listening, where each component of the chain is chosen separately.

What to check before buying used
When buying used, it is worth checking the condition of the XLR connectors at the input and output, which are often subject to wear from repeated connecting and disconnecting. Checking that the internal power supply works properly and that there is no unwanted noise on power-up also helps ensure that the amplifier retains its original performance, particularly the low background noise level stated by the manufacturer.
