Hello Zexion
I don't have as much experience with amplifiers as the Sennheiser GSX1000.
But I have retourned my Lightsync. The bass can't be adjusted, the sound is okay, now I think it gives better.
The bass was pretty blatant and since I couldn't adjust it, I returned them and used my old Logitech 5.1 speakers again.

The lightsync is okay, but you don't really notice it.

I imagine the Z333 would be a better choice for you.
