I enquired about the picture quality of the pioneer 436 xde compared to the panasonic pv500 range and this is the response I got fom LE Concepts: Dear Sir, Thank You for your enquiry. The Pioneer PDP-436XDE is a huge leap in terms of picture quality over the Hitachi 42PD5200 screen you currently own and is significantly better than the Panasonic PV500 range by eliminating solarisation, eliminating false contours and the artefacts that result from this and certainly offer the same depth of black to white gradation as the Panasonics. All of this we have demonstrated in store on analogue and digital TV reception and cable/sky and DVDs. The Pioneer has a huge range of picture adjustments that the end user may perform and we are looking to offer a professional calibration disc with each screen sold. I would suggest that this is the best plasma screen ever released onto the market. Pioneer PDP-436XDE Kit £2499.99 3 Year Warranty sounds good to me!
