Never tried Audience, but can recommend Grover Huffman. They do everything you mention and come with a 60 day guaranty and you'll come in under your budget.
Power cable for quiet background
I am having Audience powerchord for cd player and tube int amp. I need suggestion for an upgrade that does not alter current characteristic of the system. (open and detail and great soundstage), and would give a more quiet background. Looking for $500 each. New or used.
