Pass Laboratories just introduced the X260.5 Power Amplifier for audiophile and home theater applications. The X260.5 is a powerful 260-watt mono-block amplifier embodying the design technology and refinements of Pass Labs' acclaimed X Series amplifiers, including extensions of its patented Super-Symmetry circuit.

The Super-Symmetry topology, developed by audio innovator and company founder Nelson Pass following 19 years of research, earned its patent in 1994. It improves performance by precisely matching characteristics of the two halves of a balanced amplifier. To the extent that distortion and noise can be made to appear identical at the two output connections, the X260.5's balanced output will not detect them.

In conventional amplifiers, under ideal conditions, ordinary matching techniques can achieve improvements by a factor of about 10. In the X260.5, Super-Symmetry lowers distortion and noise by an additional order of magnitude. It delivers the sweetness, staging, and detail of very simple circuitry up to kilowatt power levels and beyond.
