The locals describe the climate here as 'perfect one day, better the next'. It's probably just as well that our systems sound different every time we listen since it makes life more interesting. It would get boring if our systems sounded the same all the time. Probably the way to make your system sound its best is to have an extra system that sounds really crappy. Play some music through it first, shudder, and then change to your regular system which should then sound marvellous.
I have made some progress in that I have built a workbench to eventually build amps and also installed a shelf rack to hold tools etc. You can see a photo down at the end of this blog entry.
