I just want to find out what brand you guys prefer to connect my Outlaw 755 (200x5) amp to my preamp. Need five .5m cables for around a $100. I came across "Signal Cables." Are they any good? Right now, I'm just using very cheap "RCA" cables to connect the two. Will upgrading to those exotic brands be any improvement? I notice that some brands can cost a fortune. Any advice will be appreciated. Thanks.
