I am sure I have read on a few sites one should not get a set calibrated until after a "fair" bit of usage. That to my mind means the figures can drift during the bedding in period. So even if one bought a set spot on who is to say a few weeks later it has not regressed.I've had the Gz2000 for nearly a week,my Af9 got panel issues and currys couldn't replace it.
They offered a Ag9, but took the price of what the Ag9 costs and paid the balance for my current Gz2000 .
which I'm glad I did as couldn't be more happier with it.
