What customers say
Customers view the Pass Labs XA160.8 monoblocks as foundational components delivering profound satisfaction. The core theme is unparalleled musicality, often described as liquid and organic. Users consistently praise the massive Class A bias, which provides 30 watts of warm, detailed, and nonfatiguing power. These amplifiers offer exceptional control over demanding speakers, especially delivering deep, taut bass. The XA160.8 successfully merges the finesse of low power designs with the dynamics needed for large music. While size and heat are noted, the sonic excellence justifies the trade-off. This is seen as a worthwhile, lifetime investment for serious audiophiles prioritizing emotional engagement.
Know before you buy
Pure Class A operation ensures that the transistors are always conducting, which eliminates the switching distortion found in many other amplifier designs. This results in a smoother, more natural sound with exceptional detail and musical realism.
Yes, the XA160.8 is designed specifically for demanding loads. With 72 output power-MOSFETs and a robust power supply, it provides the high current and precise control necessary to drive complex speaker designs with ease.
The XA160.8 features both balanced XLR and single-ended RCA inputs. For the best performance and noise rejection, we recommend using the balanced XLR inputs if your preamplifier supports them.
Each unit weighs 123 pounds and measures 19 x 21.5 x 11 inches. Due to their weight and the heat generated by Class A operation, you must ensure your rack or stand is structurally sound and provides ample ventilation space around the units.
The high input impedance of 50/100 Kohms ensures that the amplifier does not place an excessive load on your preamplifier. This allows for better signal transfer and ensures that your source components can perform at their best without being strained.
The XA160.8 uses banana plug connectors for the speaker outputs. You should use high-quality speaker cables terminated with banana plugs to ensure a secure connection and optimal signal integrity.
