The difference between an ordinary and great-sounding amplifier, at any price point, comes down to the experience, care, and knowledge of the design team; with many hours listening to and fine-tuning the product to provide the best sounding result possible.
Unity Amplifiers were developed and tuned by a team with over 40 years of amplifier design experience, and as a result, they yield a warm, detailed, and accurate musical presentation that is rare in this price class.
