I bought Burson discrete audio Opamp type : standard fly lead. Replaced Opa627au*2 in Xiang Sheng DAC-02A upgraded with little mod cap and tube. First listen was amazed and excited. I

t’s sound next step from any opamps. I can listen any kind of music without hiss or noisy. Everything are improved and more audiophile.

I’m very impressed !!!
