Pass Labs X 250.8

Description

Pass Labs X 250.8 – Reference Stereo Amplifier

El Pass Labs X 250.8 it is a power amplifier that combines Nelson Pass's classic philosophy with the more refined engineering of the “.8” series. With an output of 250 W per channel into 8 ohms (y 500 W at 4 ohms), it effortlessly drives even the most demanding loudspeakers, always maintaining absolute control and extraordinary musicality.

Its design operates in Class A for the first 25 W, moving afterwards to Class AB imperceptibly. This gives it the smoothness, detail and naturalness characteristic of Class A, alongside the power and efficiency required for large rooms and complex repertoires.

Built with an oversized power supply, more output MOSFET transistors and large-surface heat sinks, it ensures stability, low distortion and long-term reliability.

Esthetically, it maintains the characteristic sobriety of Pass Labs: a brushed front panel with the iconic backlit blue VU meter, accompanied by solid side heatsinks that underline its vocation as a serious and definitive machine.
