Short Run .5M Interconnect on a budget?

Hi Dhcod, the Lightspeed Attenuator likes to see interconnects to the power amp with capacitance of less that 100pf (picofarad) per foot The .5mt should not be a problem with any good quality interconnect, the sounds of which are personal and system depentant taste.
I always say that if you want to add a touch of brightness go with silver or silver coated cable, if you want to tame a bit of brightness then go with copper cable. And of course you can have a combo of silver going into the Lightspeed and copper comming out.

Tough to say. An option is 47 Labs OTA Storatos Cable and two sets RCA plugs for total of $300. In short runs, they are tonally superior - imo, in my system - than Museaus, but do not provide the pitch black background.

I like Signal Cable products. well made. affordable. nice looking. For 2 pair: Analog One - $72. Analog Two - $100. Silver resolution - $200.

I recently added Grover Huffman interconnects and speaker cable with revealing results. Planned a shoot out with anti-cable, nordost, signal, reality, blue jean. Never happened. The Huffman went in last and never came back out. So clearly superior to the others in my system. Nice guy too
