I USE CANARE RCA TO CONNECT 3800 TO 7400, I THINK IT'S A GOOD C/P RATE CABLE, YOU CAN ALSO CONSIDE BELDEN AS WELL.
I USE TO CONNECT LIKE THIS "前中置BI-AMP駁adcom後置駁返MY OLD OLD 馬仔AMP "
HOPE CAN HELP!
canare not bad ...i try to compare with some $2000 pair cable , honestly , the sound feild was different but the signal % was just the same , so i guess its good enough to go if you are not expert for stereo adjust vocal.
