Emotiva BasX A2+ Stereo Power Amplifier (160W x 2)

The Emotiva BasX A2+ is a two channel Class A/B power amplifier built for people who want more grip and headroom than a receiver's internal amplification can provide. It delivers 160 watts per channel into 8 ohms with both channels driven, and 250 watts per channel into 4 ohms, drawing from a linear power supply with an oversized toroidal transformer. That combination is what lets it stay composed when a demanding pair of speakers asks for current, rather than running out of steam at the point where the music gets interesting.

Connection is straightforward. Balanced XLR and unbalanced RCA inputs are provided for each channel and both stay active at all times, so the A2+ drops into a system built around a stereo preamplifier, a DAC with variable output, a surround processor, or any AV receiver with preamp outputs. Trigger in and out handle power sequencing, and an auto on mode will wake the amplifier when it senses signal at the input. Automatic 115V/230V line voltage detection means it runs on Indian mains without any switch to set.

Why Consider the BasX A2+

Most stereo and AV receivers give up long before their volume control does, particularly with 4 ohm speakers or in rooms with tile and marble surfaces where you end up playing louder to get the same sense of body. The A2+ solves that by taking the power amplification job away from the receiver entirely and handing it to a properly specified linear supply and a discrete Class A/B output stage. The result is not a change in tonal character so much as a change in control: bass tightens up, the soundstage holds together at higher levels, and dynamic peaks stop compressing. Because it accepts both XLR and RCA on every channel, it works equally well as the first step into separates or as a front left and right upgrade inside an existing home theatre setup.

Ideal For

• Owners of an AV receiver with preamp outputs wanting stronger front channels
• Two channel systems built around a stereo preamplifier or a DAC with variable output
• Speakers with 4 ohm nominal impedance or low sensitivity ratings
• Larger living rooms and hard surfaced apartments needing extra headroom
• Second zone installations where hi-fi quality matters more than convenience features
• Listeners planning a staged upgrade path from receiver to full separates
