What Interconnect for Mcintosh mr-78 tuner

I recently purchased this piece and I would like to know what Interconnect would sound good with this tuner. I have tried the Audience au-24 but it sounded thin with this tuner.
I have also tried wy-wires and it sounded good but I don't want to spend 800.00 for an Interconnect. My budget is between 200-500 and I don't mind buying used.
