Well, I'm not one to tell anyone on how they should spend their money. All I can tell you is if it were me, yeah, I'd go for it. It takes away all the what if feelings and questions that might arise.
Then again not everybody experiences that. There are a lot of very happy 60's owners out there, and I have no doubt that you'll truly love yours as well, should you decide to stick with them.
That being said, if you got the extra dough, and would like thier flagship speakers, then by all means, yes, go for it buddy!
