I hope you had a great time in Brissy Adrian.
Adrian, had I realised in time I would have tried to help you out or pointed you in the right direction, as I have a fairly good understanding of amps. I make a point of only buying audio equipment from specialists (Todd's HiFi). There are lots of amps that all look the same so if you don't know what you want, I guess it can be confusing. And with an amp, you want to to get it right as it's the backbone of your whole set up. Hope you are happy with what you ended up getting anyway.
A couple of years ago lightning blew up one of my amps (yikes it was a $3000 one and luckily insurance covered it, but that's another story) and ever since then as soon as I hear a storm, the lead gets pulled out from the wall. I got told by an electrician that this was the surest way (as compared to surge protector boards) to prevent damage.
If you don't already have OFC cables (oxygen free copper) get them- I can't speak highly enough of them, really does make a difference. And there's also a few easy neat little tricks to increase the perfomance of speakers, but that's a whole other discussion

I love amps as much as I do scopes (yes, I did actually just say that

), especially if I can manipulate sound waves on them
