I just replaced the straps with wire. I cut two short pieces of speaker wire, stripped the insulation off both ends and attached the right top post to the right bottom post and did the same with the left posts. I can't say at this point that it sounds better than how it did with the metal strap, but it certainly sounds just as good. But in my case because I lost the metal strap it sounds remarkably better than having nothing. My ears are happy now.
