At the heart of this stereo is a hybrid tube amplifier with vintage flair and modern connectivity. By combining a tube preamp with a contemporary solid-state amplifier, the HTA20 provides the warm and fuzzy sound characteristics associated with vintage tube amplifiers while generating clean and efficient power common in modern amplifiers. Simply stated, this will sound amazing while remaining as energy-efficient as possible.
