Feedbacks - V4 SS Opamp
ASUS Xonar Essence STX

I just received a pair of the dual Burson Supreme opamps and i am very very impressed! the difference was so much bigger then i actually expected to be, rich but tight bass responds and clean soft highs. just how i like my sound so that was a great purchase.
