The Point 5 Series represented a highpoint 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.

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.
