A few people have been asking me about the cost involved and TBH I wasn't really sure of the total myself so I knocked up a little spreadsheet with the info. I converted it to HTML using Excel so I hope this works:
Cost breakdown
So, the total was 1106.97 Euros, roughly £740. I could have saved a lot of money by building my own PSU (the massive V4P LC Audio one is overkill really) and by ordering the quantity of wire & cable from them that I really needed. I've got enough of their special "Teflar 2" speaker wire (used to connect the modules to the speaker terminals) left to make a decent run of speaker cable! I ordered 10m and actually needed about 1m 
Still haven't had a chance for a decent listening session yet
