Audiogon speaker wire gurus, please help me

I need help form the audiogon experts. I want to upgrade my audioquest gibraltar speaker wire. Current components are dali ms4 speakers, cary 500mb monoblocks, first sound preamp, richard gray power, and acoustic zen reference + transparent audio interconnects. The room is excellent sonically (designed by Rives) and does not add any sonic signature. I'm looking for some warmth, a large 3-dimentional sound stage, and air between instruments. My budget is 2-3K for 10 ft of speaker wire (bi-wire). Can anyone help me out with suggestions? I will confess to having no knowledge of speaker wires or cables, and unfortunately have just been taking suggestions until now from people who have an interest in selling me something. Am looking for unbiased opinions. Thanks guys!
