Audio Sensibility Impact SE. They dont break the bank and made a very audible improvement in my setup.
I agree, after trying some more expensive din to rca interconnects I stumbled on the Audio Sensibility. I use them on all my turntables, and was so happy with them that I use a pair of 3.5mm to rca connectors to hook my Ipod (lossless files) to a stereo and a 3.5mm male to male to play the Ipod in my vehicles. My wife noticed the instant improvement. The "impact cables" are good, and as you go up the ladder, they get even better
I'm not saying that the Audio sensibility are the best interconnects money can buy, but for my $$ I've been really impressed. Since these products are not sold in the store, there is no markup. Steven Huang has always given me great service, and has made custom cables for me.
