DAC ZD3 and OP Amp swap

[delaforetnoire]

As you know, ZD3 allows OP Amp swap to improve, or change, the sound.

I open this track to share your experiences here.

●● In wich technical way, OP Amp in a DAC can color the sound?

☆☆☆ Lets try, listen and share ! ☆☆☆

I have to say that the sound with original opamps is the same than with my Topping E30 pro II, really good but same mood, à lot of clinical trebbles.

With the other opamp provided by Fosi as a gift, this is another color : the trebble is softer, the médium is forward with a magic warm, the bass is in perfect place.
This is less tiring for long hours of listening.

The change is a real thing, not a psychoacustic perception.
