Post Info

The opamp works great in the X-duuo XD-05 Basic, however, when installed in the Little bear B4-X, it introduces a hiss noise and it can be perceibed at low and medium volumes. A total of three were bought and the one working in the X-duuo works without issues, but the other two had this issue right out of the box
