I have upgraded the speakers in my theatre room and have for sale 7 x Wharfedale Diamond 8 series speakers. 2 x 8.3 Floorstanders, 4 x 8.1 Bookshelf and 8 Centre. All in excellent condition apart for 1 small mark (about 5mm in size) on the top back corner of 1 of the 8.3. The speakers are black in colour and available for pick up in Currans Hill 2567, SW Sydney. After $450 for the set, would be a great set of speakers for someone starting out on a budget.
The key differences are the THX Optimsizer has Brightness (PLUGE), Contrast (Sort of ramps test), Colour and Tint where it uses the phones camera along with a colour filter (it uses red and yellow?) instead of the more traditional blue filters. Those cardboard and plastic filters that come with the discs are pretty far off, so best not to use them. You also get a sharpness pattern and geometry pattern.
S&M has all this plus 100 other patterns that are way more specialised.
