balanced to unbalcned circuit before TPA3116 amplifier

I have used successfully (thanks to this forum) the above amplifier for an 8 speaker installation I build. (powered from 24V dc PSU)

I would like to rebuild this project and I wonder if using a balanced to unbalnced board before that amplifier will improve the sound?

the input signal is from computer via an motu ultralight mk2 interface.

Is it acctuall need to make the signal unbalacned before feeding the amp?

another question is this amp board will be better quality for 8 small 8ohm speakers?
