Difference from Ayre V5X and V5XE amps ?

I have the ayre v5x amp and I am very satisfied, should I consider upgrading to ths 5xe, can anyone tell me if it is worth it, thanks
I have a V1xe and it was worth updating. Call Ayre and speak to Michael Weidermeir. He is in charge of production and updates...one of the nicest people I've ever met. He will give you the scoop on the project.
Just for your reference, the price of the upgrade from a V-5x to a V-5xe in the US is less than 10% of the original price of the unit. While it is here at the factory, we will also perform a full battery of tests and make sure everything is running properly. And finally, the resale value will be increased.
