100% Authentic! All packages are shipped directly from Japan! Our shop always ships in cardboard boxes. We can deliver it safely. Dont worry.Condition DescriptionThe power supply unit and cable are made new again, and I have them check the sound output adjustment with the main unit. Therefore, all operations have been confirmed by the manufacturer. Description Ishinolab MASTERS SX3000BD STAX Headphone Balance Amplifier Condition : Used MASTERS SX 3000 BD from Icinolab. Not only does it have a phone-out XLR balance out, but it also has an output for STAX, making it an all-in-one luxury. The power supply unit is a separate, separate chassis, suitable for high-end amplifiers. I opened the unit when the power supply failed. At that time, I lost about 4 screws in the case. I think you can buy it at the hardware store because it is a black plate screw. Used in HIFMAN HE6, SENNHEISER HD 800 Beyerdynamic T1, Audeze LCD 3, STAX SR009, etc. Thank you very much for visiting this page! We carefully pack your products and ship from Japan.
