MEASUREMENTS
rior to measuring the Pass Labs INT-25 using my Audio Precision SYS2722 system, I preconditioned it for an hour at one-third power into 8 ohms. At the end of that time, the heatsinks on the amplifier’s sides were hot, at 122°F (50°C), as was the top panel, at 116.6°F (47.8°C). Owners should make sure this amplifier is well-ventilated. The amplifier’s maximum voltage gain into 8 ohms was 25.4dB, and the amplifier preserved absolute polarity (ie, was noninverting).
