Ayre MX-R upgrade costs?

If I recall correctly, it it about $11K. From what I have heard the '20' upgrade is a significant improvement.
BTW, I own the MXR's, too, and I have a hard time believing that they can be made any better.
I would contact Ayre's Michael Wiedmair and get it from the horse's mouth. Though he can't say if it is 'worth' it, he can give you the details on what is upgraded and why it is done.

I recall hearing that Ayre increased upgrade prices last December. Oh well, I’m not in a rush.
Good to know about Michael, he was always my go to guy.

Actually, looking at the website, I recall seeing that they replace everything except the connectors and something else- Which seems odd as it wouldn't significantly add to the upgrade cost. Perhaps they still use the same parts in the Twenty version.
