Replace Audio Envy (-1) with AntiCable (+1).
The Audio Envy were very dry and thin sounding. I tried to give them away, but no takers.
The AntiCable are simple, clear and inexpensive. ($50 to $500 per pair, depending on the materials and length / Award Winning Analog RCA Interconnects and Interconnect Systems (anticables.com). There are others to try, but these have worked for me.
I am not in the audio business and have no affiliation with either company.
Good luck
