Interconnect recommendations, please


I've recently revamped my system with a new integrated amp (Teac AI-2000) and new DAC (Burson DA-160). Overall I'm really happy with the changes and now am looking to find the right ICs to dial the sound the rest of the way in...

Specifically I'd like to find some ICs that will bring out a bit of high-end sparkle, inner detail, and air/openness to the sound.

My current ICs are Cardas Quadlink 5C so I'm looking for ideas that would provide a relative improvement over those in the areas noted above. Budget is about $150-$200 for a 1M pair, new or used.

Thanks in advance for your suggestions!

Recently I purchased some Atlas Equator 2.0 spk. cables from Futureshop.co.uk (also HifiCables.co.uk) and if their IC's are anything like their spk. cables. Oh my goodness. What fantastic spk. cables for a very reasonable cost. Very well constructed and the copper wire is 6N and 14ga. My next purchase will be Atlas Equator Mk 2 IC's. Please do check out this company out. I'm very impressed.
I like the over achieving Condutor by Audience. It is their entry level cable that hasn't gotten a lot of press here.
In general you probably want a cable with some silver in it. The Conductors don't but have an open and neutral sound anyway. You might want to check out Home Grown cables. I use the Silver Lace which has been subject to rising prices and is over your budget but they make some that are less expensive. The other thing that should go without saying is to buy used cables, they almost always represent a good deal.
Grover Huffman. Interconnects compelled me to go all Huffman. Did for me what you are looking for in addition to presenting the music with a "wholeness" I'd never heard. Not too expensive. Wonderful guy to deal with.
I found the 5c's sounded a bit on the dark muddy side when I used them in a old system I had. A lot of good suggestions above to which I'll add JPS
