The Pass Laboratories INT-60 and INT-250 integrated amplifiers build upon the INT-30A model's soundstage, specializing in "realism" and handling electrostatic and planar speaker loads.
The INT-60 features the same power supply and output stages, along with the glowing meter found on the company's Point 8 amplifiers. The new model features direct access buttons for the four inputs on the faceplate, digital level display, volume control knob and mute button. On the back are four line-level inputs, a line-level output, and two pairs of Furutech speaker binding posts.
The INT-250 increases the wattage from the INT-150's 150 watts to 250 watts per channel. The INT-250 can handle speaker loads of 86 dB efficiency or less. Like the INT-60, the INT-250 features the same power supply and output stages, along with the glowing meter and the same inputs, outputs and control options as the INT-60.
Both the INT-60 and the INT-250 are designed for reference systems or secondary audiophile systems, and were optimized by listening processes using six different sound systems.
