"The McIntosh MHA200 Tube Headphone Amplifier is a contender for the best tube headphone amp manufactured to date, and easily outperforms more complex and unnecessarily feature-encumbered designs loaded with unnecessary additional tubes… It has ZERO musical flaws to report and is nearly perfect in execution." Highly recommended. – Positive Feedback
