Here's an idea for a neutral cable at your price point:
Cardas Audio 1 meter Neutral Reference RCA... For Sale | Audiogon
The Cardas can a little laid back but will be very quiet.
I'll bet you could get a pair of the Cerious Matrix from Bob if you go to his ad and offer him $400.
$500 or higher gets you much better options. Sort by price and see what is available here like I just did.
