无源前级（或带buffer的无源前级）

Thanks Nattawa, very professional!

I am using w4s stp-se which is a passive pre-amp with buffer, feed by an Apogee pro DAC with high output (over +4 for sure), drive a active pro monitor with +4db input sensitivity, sounds pretty good to me. If I use SPL, it sounds "aggressive" sometimes, and volume had to be kept down to very low settings, which can be a bad thing as you said..
