Pass Labs XA160.5 Monoblock Amplifier

Class A operation means the output transistors are always conducting, which eliminates switching distortion and provides a highly linear, warm, and detailed sound. It is widely considered the gold standard for high-fidelity audio reproduction.

Yes, these units require a 220-volt power supply to operate. Please ensure your listening room or dedicated audio circuit is equipped to handle this voltage before purchasing.

No, this is a normal characteristic of high-bias Class A amplifiers. As the internal components heat up and expand, you may hear slight clicking or ticking sounds, which is a standard physical byproduct of the thermal management design.

These amplifiers are designed to drive demanding, low-impedance loudspeakers with ease. Their high current capability ensures excellent control and dynamic range, even with speakers that are typically difficult to power.

No, the power cables are not included with this pair. You will need to source your own 220-volt compatible power cords to connect them to your wall outlet.

The monoblock design provides complete electrical and physical separation between the left and right channels. This eliminates crosstalk and ensures that the power supply for one channel does not impact the other, resulting in a superior soundstage and imaging.
