Hi Larry,
I don’t know which Arcam amp you own, or if all are the same. But I owned an Arcam Alpha 10 years ago, and it required BFA style banana plugs, such as Nordost Z-Plugs which are hollow. I used Nordost Super Flatline cables back when I owned that Arcam amp. I really liked that style banana plug and have been using them ever since. IMHO, they are a fantastic connector and I prefer them over spades. They have great contact area and, buy nature, have constant outward pressure, holding them firmly in contact with the inside of the binding post.
If it were me, I would get the cables fixed. For anything near that cost, you’re not likely to get anything better.
My current speaker cables are simple Audioquest Type 4, no frills cables from Audio Advisor. They use the BFA style, low mass banana plugs. I have bananas on both ends because I prefer them. They don’t loosen like spades sometimes do. I checked Audio Advisor earlier. All of their speaker cables said "temporarily out of stock". Likely a victim of COVID induced supply chain issues, or possibly staffing issues for building their cables.
Good luck with whatever you choose.
