Hi, I would like to calibrate the Loewe Xelos SL32 and the Pioneer 504. I've read about how important proper screen calibration is, so I wonder what tools are available (and where to buy them from), and what advise (maybe procedures) can someone give me. This would be a DIY job, so any pointers, links, sample pictures etc. would be appriciated. I have never done this before, and my new Xelos will be arriving on monday. The pioneer will be my next purchase (this is for the launge) about 3 weeks time. Enough time to play calibration on the Xelos. Any help would be appriciated.
