Lab 12 Mighty Power Amplifier Review: A Masterclass in Single-Ended Class A Amplification
After spending considerable time with the Lab 12 Mighty Power Amplifier, it's clear that this is no ordinary piece of audio equipment. This Lab 12 Mighty Power Amplifier review reveals a masterpiece that combines classic tube amplification with modern engineering precision.
