IC advice


looking to upgrade my current pre-dac IC (aq diamondback) with up to $200 pair. my pre is lector zoe and dac is by prometheus audio.
looking to improve on wider soundstage and bass reproduction and to have an overall good cable.

short list so far:

used nordost red dawn
grover huffman IC's
TMC yellow lable

any opinions on my list ? any other suggestions ?
added to the list HGA silver lace.
any responses ?
Why isn't Anti-Cables on that list.. In my system, it was better than any other cable I tried including multi-thousand dollar cables.
