However, despite its many strengths, the Douk P1 is not without drawbacks. Some users reported the absence of an optical input as a limitation for those looking for versatile connectivity options. A common annoyance is the bright blue LED on the power supply, which, according to users, can be distracting in a darkened room. Additionally, a tapping or clicking sound when switching power modes has also been noted, although most users responded to this quirk with little concern, recognizing it as a benign characteristic of the product. Overall, the Douk Audio P1 emerges as a solid choice for anyone looking to enhance their audio experience without breaking the bank. Its impressive performance and compact design, paired with a few minor issues, place it among the best value-for-money options available today. #### Pros and Cons **
