Best RCA to mini adapter or RCA to mini cable?

Thanks everyone, I appreciate it.

The Zu Pivot is a good cable. Big, big improvement over a Radio Shack I had or the readily available Monster (though it was significantly better than the RS and cheap at $20). The Zu is good value, especially if you get it on auction at ebay. Clearer, more open, better highs. I'm now experimenting with a Bis Audio cable with copper Eichmann RCAs that they made up for me and am even happier. Vinnie at Red Wine Audio likes the Audiopath cable -- silver with silver Eichmann and the guys at 6moons like the Crystal Cable. Try 'em all and let us know!
btw use Apple Lossless on your iPod.

Yea, Apple Lossless is great. Anyone have any experience with Blue Dragon RCA to mini from moon audio? I bought there Blue Dragon Sennheiser headphone cable and it sounds real balanced. Great improvement over stock. Wondering if the Blue Dragon connector is the best way to go since its voiced match to the headphone cable. Any thoughts?

I second the Audio Line Out recommendation, but would add that for a laptop, USB is worth exploring (via a USB DAC). also, for the iPod there are min-to RCA cables from Kimber and Cardas that are better than most mini-to-mini solutions.
