(Install the part01 of the stereo-wet version. Install the part01 and then the part02 and part03 of surround version. It is important to sort.)
Wet-stereo version The price is only € 89.
I suggest you buy only after trying the demo.
Surround vs Stereo mode
If you do not have a surround sound system, but there is enough memory (RAM), I suggest you also install the surround version. If you activate the front and rear stops too, then you will get a more compact and fuller sound than the simple stereo.
Surround (and wet and dry) version The price is only € 109.
Upgrade from stereo to surround version The price is only € 20.
