Hello Edmund,
I just got delivery of my new A5 Domnator too.
First impression is it is very noisy.
Second impression, after 1 week of mining I have calculated that I have got 180 Years of mining ahead of me to get my $ 10,000 back !
I now think that I have made a very very bad decision to buy this machine.
I should have stuck with Litecoin, rewards there are much better.
