The BASX A-100 is a great sounding, compact, and very flexible, stereo amplifier. The A-100 includes features that make it an excellent choice for a wide variety of situations; from driving a small music system in a home or business, to providing audio for a second zone in a larger home theater installation, or whole house music system. The A-100 also includes a great sounding headphone output, which combines the sonic signature of high-end vintage equipment with the superb performance of modern circuitry, and which offers the ability to drive low-efficiency planar headphones without the need for adaptors and custom cables.

Headphone Output

Headphone Output

Driven from the main amplifier outputs via a set of high-quality series resistors, the headphone output duplicates the sound signature of the highly-prizes headphone outputs on high-end vintage equipment. There is also a direct drive output option to properly drive low-efficiency planar headphones without special cables or adaptors.

Heavy Duty Power

Heavy Duty Power

The heavy duty power supply, with massive toroidal transformer, provides plenty of continuous power to drive even low efficiency speakers, and enough dynamic power to effortlessly reproduce musical peaks without strain or distortion. High power in a convenient compact design, and fan cooling ensure high performance high quality reproduction.

Best-in-class Design

Best-in-class Design

The A-100 shares the same superior design and high- quality parts as our bigger amplifiers, so it performs “like the big boys” and sounds far better than most amps in its price and power class, and delivers upto 80 watts per-channel sufficient to drive most speakers to satisfying listening levels.

Illuminated Front Control

Illuminated Front Control

The A-100’s volume knob is surrounded by an illuminated ring, which indicates both Power and Fault status. With the convenient analogue front panel volume control, the A-100 can accept inputs from both variable and fixed audio sources. A loop output on the rear facilitates chaining additional amplifiers or other devices.
