Pioneer were displaying their 506 XDE showing bog standard DVD and 436 XDE showing Hi-Def 1080i at the Scottish Hifi show today. The blacks are just outstanding and a big difference from my 434. The bezel is thinner than the 434, so it does look a bit smaller. Loved the blue power LED rather than the green LED that the 434 has. Very impressed by these two it must be said. On the way home, popped past Comet in Buchanan Galleries, they have a 436 XDE and a Pana 500 Viera side by side showing a Hi-Def feed. Both were very good but the Pioneer was just that bit better. Best price I could find today was 2600 for 436 XDE with side speakers and swivel stand. Also visited John Lewis in Glasgow. They have no Pioneer plasmas on display, but I did find the 436 XDE was priced at 2795 no speakers.
