Biwire fix

My uncle has been downsizing and gave me a pair of mint condition B&W Matrix 801 S2s.

He also gave me a box containing really thick (wide diameter) biwire cables called MIT2, and some really thick and stiff power cords from demo shows years ago. There was also a black box (Maughanbox ListenUp) for bass augmentation. He and two of my other uncles were contributing editors in the 70s for a while and even published in the Absolute Sound when it was the size of a thin Reader’s Digest book.

The B&Ws are pre production eval units he ended up purchasing after one of his demo shows. Lots of cables and power cords have "For Demonstration Only" labels.

The spade connectors on the MIT2 biwire amplifier end are smaller than normal. They are too narrow to fit on the binding posts at the amp. They actually fit around the posts on an old Forte 1A but not the Hegel or my Ampzilla monoblocks.

Is it worth it to switch for larger spades? Anyone familiar with this cable from the past?

I would rather not have to purchase 2 pairs of speaker cables (or even one pair if jumped).

So anxious to hear them!

Thanks everyone!
