I have a pair of 10Ft long, MonsterCable M series MCX-1s Bi-wire for sale. They have Bananas at the amp end and gold, large spades at the speaker ends. They have the monster cable interlock connections so you can change the connection type by unscrewing the connectors and replace them with bananas, pins, what ever you want.
The cables are in great condition, originally cost $85, plus $25 for the connectors. Looking to sell them for $45 or will consider trades for a good component cable (Audio Quest YIQ-1 1.5 Meters, etc)
