Taxes & Shipping Included
Whether you're putting together a new stereo audio system, adding more channels to your current system, or upgrading the performance of the front channels of your current stereo or surround sound receiver, the BasX A2+ is the perfect solution. The BasX A2+ offers advanced design features, including a beefy linear power supply, built around an oversized toroidal power transformer, a high-performance Class A/B output stage, and both balanced and unbalanced inputs. More importantly, the BasX A2+ delivers the true audiophile sound quality you normally expect from far more expensive amplifiers, and all at a truly affordable price.
The BasX A2+ is a two-channel power amplifier that delivers 160 watts per channel into 8 ohms and 250 watts per channel into 4 ohms, all channels driven, with a rated THD+N of less than 0.02% and an A-weighted signal-to-noise ratio of 112 dB. The A2+ features a robust linear power supply built around an oversized toroidal transformer, a refined Class A/B output stage, transparent fault protection, and both trigger input and output for flexible system integration.
New to the A2+ are balanced XLR inputs in addition to the unbalanced RCA inputs for each channel, giving it even broader compatibility with a wide range of stereo preamps, processors, and receivers with preamp outputs. The heavy-duty five-way binding posts accept banana plugs, spade lugs, or bare wire for solid speaker connections. Together, these features allow the BasX A2+ to deliver clean, dynamic audiophile soundat a price that puts high-end performance within reach.
The BasX A2+ is the perfect solution anywhere two channels of reliable, great-sounding power are needed. It’s ideal for building a dedicated two-channel system with a stereo preamp or DAC, and a smart way to upgrade the front channels of a surround sound receiver or a stereo receiver with preamp outputs. It’s also well-suited for powering a second zone with true hi-fi clarity.
Whether you're a newcomer stepping into high-performance audio or a seasoned listener building out your system, the A2+ brings serious value, versatility, and sound quality to any setup.
