The X260.8 is a refined musical instrument delivering 260 watts into 8 ohms, and combines power and finesse with all the benefits of mono-block performance. Its measured performance - distortion, bandwidth, noise, and resolution is beyond reproach. Like all of the class A/B .8's, this amplifier has some class A bias, rewarding its listeners with a whole new zenith of sound quality.
