Interconnects for Rotel amp/prepro

Perhaps this would be more appropriate in the Cables category but it also fits the Amps/Preamps category which is probably viewed more than the Cables area. Can I ask the forum who owns and uses Rotel multi-channel amps powering a Rotel preamp/processor or AVR which audio analog RCA cable interconnects you are using (length, brand, model or series, price each)? Which brand really opens up the potential and soundstage/detail of Rotel equipment preferably with B&W loudspeakers?

I'm on a budget (max $40.00 each interconnect) and am considering Audioquest Alpha-Snake or G-Snake, Monster Ultra Series THX 600 or 800, Blue Jeans LC-1, etc. My length is 4' per interconnect x 5 (5.1 surround sound). Thanks.
