Best RCA interconnect up to ~$100?

A third vote for DH Labs interconnects. I got 2 pairs of used 1-meter DH Labs BL-1 Series 2 interconnects for $75 total off of eBay. One of my best audio buys ever. 

The DH Labs interconnects seem good. I need 6’ (2 meter) pair currently $220 on ebay. I’ll keep my eye out. Thanks

I'd check Pine Tree Audio ...

AudioQuest Golden Gate are around $140.00.  Have a pair coming today for my new Mofi Turntable coming next week.  I have read good things about those cables.  We will see I guess. They have to be better than the 20.00 cables I have laying around right?

You can’t go wrong with Blue Jeans at your price point. Also, I’ve had good luck with custom cables made by performance audio in Salt Lake City. Great to deal with, lots of wire & design options, and high quality.
