About the TPA-30

The Thor Audio TPA-30 is a 30-watt monoblock tube amplifier featuring EL34 push-pull output tubes and a custom-built 60-watt power transformer designed to deliver clear, unrestrained, and liquid sound quality. It has a compact and elegant chassis with all controls, including fuse replacement, bias adjustment, and a built-in bias meter, accessible from the top for safe and easy operation without opening the unit. The biasing system allows on-the-fly adjustments while the amplifier is playing, using toggle and rotary switches that automatically shunt the input to ground and power the bias meter. The amplifier is known for its dynamic capabilities, excellent transient response, wide and deep soundstage, and neutral tonality with a slight tube warmth. It reproduces high frequencies with good extension and air, detailed midrange with lifelike presence, and tight, extended bass. The TPA-30 is highly regarded for its combination of performance, user-friendly design, and aesthetic appeal, making it a favorite among audiophiles seeking a powerful yet refined tube amplifier.
