Hearme,
I have not heard the CA 200 but it is very well regarded in reviews.
If you have the budget for it just go for it.
However, buying from the US and even Audiogon is not without risk.
I think the landed price on the A'gon listing is going to be more than $3K
There was also some issues with importing used goods on another thread.
Finally there's the old 110 vs 230 V discussion - just want you to be aware.
The amp itself is a great design from CJ.
However, buying used and from the US is tricky.
Regards.
