Happy Listening!

When in doubt, call the manufacturer directly.
That being said, Ayre is one of the best companies out there.
They repaired my MX-R's after a capacitor blew up.
The cost was minimal, considering that they had to check both monoblocks in order to make sure they were up to spec.

Thanks, appreciate it. Just double checking. 

Yes they will- they charge $1500 plus around $6 for a new box.  They cover return shipping.  Took 2 weeks from door to door.

@OP, 
Yes, they will upgrade any QB-9. They did 2 for me that I bought 2nd hand. In fact, I had the seller ship them directly in order to save on re-shipping.
Also, it doesn't matter which model. They essentially replace the entire innards, so the price is the same.

Why would they care as long as you're paying?
