Must be Clear Before Purchasing:

▶ Please shop rationally and choose what you really need! Please feel free to contact us if you have any doubt or need help if you don't know how to choose.
▶ We understand that "Return & Refund" is your right, but we would like to request that DO NOT do it if there's no any quality defect, one reason is that the cost of returning through AliExpress is too expensive. Another reason is that op amp will leave traces after use and cannot be sold again. "Return & Refund" will cause us a lot of psychological pressure, and we may block your country or stop designing/selling more better products in the future. Please be a moral person, the gods will bless you!
▶ AkLIAM has been deeply involved in op amp chips for over 5 years. We ensure that all chips in our store are original and we will not compromise our brand image for short-term gains.
▶ According to our testing and feedback from a large number of users, under normal circumstances, using this op amp instead of some basic op amps will significantly improve the sound quality. But we cannot guarantee all device has this effect because the final display of sound quality depends on many factors, such as device design and user listening experience, for example, the role of op amp in circuits, the quality of decoders/amplifiers, the quality of speakers/headphones, personal sensitivity to audio, and so on, all subjectively affect the final judgment.
▶ If users can not feel a significant improvement in sound quality on a certain device after using it to replace the default basic operational amplifier of most devices, please do not rush to draw conclusions. We suggest that you test it on other devices or ask your friends with rich audio experience to help you test it. We ensure that you will ultimately feel the true value that this product should have.
▶ Before replacing the op amp, please make sure to check the channel matching and correct direction‌. Any incorrect direction/electrical short circuit, or single/dual channel mismatch may cause irreversible damage to your equipment. Please contact our customer service to help you confirm if you are unsure if yours is correct direction‌.
