Pass Labs Point 5 Amplifiers:

“The Point 5 Series represented a high point in the evolution of our amplifiers. At the time we introduced our X.5 and XA.5 models, our R&D laboratories had accumulated several significant performance improvements we were eager for our customers to experience.”

“Two hallmarks of Point 5 Series amplifiers are improved power and control. They possess the dynamic range to do justice to the most advanced recordings, the elegance to retrieve the most sensitive microdynamics loudspeakers offer, and the ability to move easily from total silence to explosive transients without losing information. We achieved these ends through a number of refinements. For example, we replaced the input differential MOSFETs on our amplifiers with the same JFETs we use for the input devices on our MM and MC phono stages.”

“The JFETs deliver less noise, higher input impedances, and greater linearity. They operate self-biased within a symmetric quad topology in which each device is cascoded and level-shifted to form the full voltage gain stage of the amplifier. We also added more power-output devices, especially complementary power MOSFETs that provide more current and better power handling and linearity. In addition, our Point 5 output stages use a heavy bias current for push-pull, Class-A operation to a large portion of the rated power as well as a bias source for single-ended Class-A operation at low wattages. We also installed a newly developed bias generator to eliminate three sources of bias-current variation in the output stage. The new bias circuit also allows approximately 20 percent greater power output for a given supply voltage. Of critical importance, the Point 5 circuits resulted in lower distortion at all power levels and into all types of loads, particularly in the critical audio midrange.”

“Finally, Point 5 Series amplifiers employ the acclaimed Supersymmetry circuit developed by Nelson Pass, which improves performance by canceling distortion and noise. As a result, X.5 and XA.5 amplifiers embody significant improvements over their classic Pass Labs predecessors, while delivering the warmth, sweetness, depth, and space that are the distinguishing characteristics of outstanding audio products. They also possess greater reliability. These amplifiers are harder to break and easier to repair if they ever do.”
