AudioQuest - Pre-Amp Jumpers ' RCA Male > Male with RCA to RCA Connectors - Black

Repeat after me, "I will not allow pre-out/main-in to ruin the sound of my system!". Most receivers with pre-out/main-in use metal pins to complete the circuit. Replacing them with the AudioQuest Preamp Jumper can, and will reduce distortion across this bridge, giving you the clean and clear sound you want.
