Avalon Symbol with ceramic tweeter

Does the ceramic tweeter make a huge difference?
Can buy a symbol ,5 year old with ceramic tweeter upgrade or a 2 year old one with the original tweeter ,for the same price.
Which to choose?
Avalon will say offcourse that it`s a big upgrade.
I like to hear if it`s worth the price difference , about 1000usd for the tweeter upgrade.
Haven't heard the original Symbol, but the new ceramic tweeter in the new Symbols sounds really excellent.
