The Pass Labs INT-250 integrated amplifier channels the authority and refinement of the acclaimed .8 series into a single-chassis design that delivers 250 watts per channel into 8 ohms. Its high-bias Class AB output stage employs a larger complement of higher-power MOSFETs than its celebrated INT-60 sibling, granting it the current reserves to command even the most demanding loudspeaker loads without strain. From the first watt onward, the circuit maintains the low-order harmonic profile and minimal feedback that define the brand’s sonic signature, preserving transient speed, textural density, and a naturally layered soundstage.
Volume is adjusted in precise 1 dB steps across a 63 dB range, while selectable gain settings of 30 dB and 36 dB offer flexibility for system matching with a wide variety of source components and speaker sensitivities. Four line-level inputs and two preamplifier outputs accommodate straightforward yet expandable setups, and the included remote control makes daily operation effortless. The chassis, machined and assembled with the understated solidity Pass Labs is known for, houses a substantial linear power supply that keeps the noise floor vanishingly low, allowing fine microdynamic shadings and ambient cues to emerge intact. Whether driving large floorstanders at concert levels or revealing the inner detail of a solo piano recording late at night, the INT-250 couples generous headroom with the kind of composure that lets long listening sessions feel effortless rather than fatiguing.
