Careful with your ears - they are yours, afterall...

One thing NOT mentioned here (there is a bunch of stuff in that OP... ), diaphragms do fatigue with age. They change character - some say, become "brittle". Dunno. But I do know that replacing them can yield a smoother and more pleasing response.

There's a Thread on here about Refresh your Vintage Compression Drivers or somesuch. Give it consideration...
