Replace Levinson 5-way binding post?

I recently purchased a used ML No. 23.5 amp. To my dismay, the 5-way posts had been damaged by the use of pliers from a prior owner. I would like to replace them. Does anyone out there have experience with this? I don't want to send the unit back to Madrigal. It functions fine. Madrigal uses cheap plastic posts and there are better quality posts available such as those from Cardas. Does anybody out there know if these will work? What type of solder is best? Are there other good 5-way posts out there that would work?

Please help!

Thanks,

Mark
