Innuous Phoenix net

I’m debating whether to add an Innuous Phoenix net to my system. I’m using  a Zenith 3, matrix spdif, Phoenix USB, and PS Audio directstream 2.  I don’t have lots of technical knowledge.  I’m wondering if the Phoenix net would result in sound improvement.  Also, how it would function with the Matrix spdif or whether I would just remove the matrix? Amy  other input would be welcome. Thanks.
