The SMSL DO400 Full Balanced Headphone Amplifier DAC has garnered mixed reviews, with many users praising its performance relative to its price, while others have criticized aspects of its build quality and sound characteristics. Users have been particularly happy with the DO400’s performance, noting that it can comfortably drive high-impedance headphones like the Hifiman HE6se and Sennheiser HD6XX. The amp delivers a good amount of power, making it versatile for different headphone types. Many reviewers appreciate the sound's transparency and the customizable options available through its filters and color settings, which allow users to fine-tune their listening experience. The recent firmware updates have addressed prior issues and contributed to a smooth playback experience, with several users reporting the absence of annoying artifacts when changing bit rates, a major improvement over previous models. However, there are notable criticisms as well. Some users have pointed out that the overall sound quality could be lacking in detail and neutrality compared to similar products like the FIIO K9, especially at higher volume levels where music can lose its fullness. Additionally, there are concerns about build quality; the thin sheet metal casing and the feel of the headphone jacks and volume knob have left some users disappointed. Overall, the DO400 presents a compelling option for audio enthusiasts seeking an all-in-one solution without a high price tag, but potential buyers may want to weigh the importance of build quality and sound characteristics before making a decision. **
