The XA 100 monoblock power amplifier embodies the design technology and refinements of the larger “XA” series amplifiers, including extensions of the patented SuperSymmetry circuit.

The XA 100 has a massive torroidal transformer coupled to a high current DC reservoir. Recognizing that the XA 100’s ability to resolve microdynamics is best experienced with clean power, the extreme low-level resolution of the XA series benefits from a specially designed power supply that significantly reduces and rejects power line borne noise.

The XA 100 will deliver 100 watts rms into 8 ohms of impedance. This is the amplifier’s class A limit, and driving the XA 100 harder or reducing the impedance of the load will not convey any additional power.

The XA 100 monoblock is packaged in an artistically refined variant of the massive chassis previously reserved for the X250 stereo amplifier.

The amplifier is 19” wide, 9.5” tall, and 22” deep front handle to rear handle. The XA 100 weighs approximately 100 pounds in the shipping carton.
