I use th Shunyata Antares balanced IC. For me is one of the best IC. I compared them with many cables from Audioquest, Harmonic Tech and Acoustic Zen, and the Antares represent a big step up. The only problem with Shunyata is the high cost. But now the Antares is discontinued, so you can buy used at very affordable price.
Hope this help you.
