Pass Labs INT-30A Pure Class A Integrated Stereo Amplifier



Recently, we reviewed the Pass Labs INT-150 integrated amplifier, which is biased into Class A at about 5 watts, and leaves Class A into Class AB at 10 watts peak. It is a superb integrated amplifier. The INT-150's brother, the INT-30A integrated amplifier, is Pure Class A throughout its 30 watt output (into 8 ohms) specification. Chris Eberle originally reviewed the INT-30A in 2010, and in this review, I compare the INT-30A with the INT-150, and add bench tests which were not in Chris' review.
