I must say that the next TV we will buy will be dramatically downsized. I will never spend more than 600€ on a TV.
The last one was purchased four years ago, an at that time 1.900€ Samsung with all the bells and whistles. Since two years, exactly when the warranty was over it shows a nasty stripe vertically at the left of the screen. Recently I read that the lifespan of modern flat screens is as short as it was never before.
I‘m a sound aficionado and happily my wife is also. I have spent the money in tube gear, a nice turntable and so on. The screens may become better over the years of development but I must not be the avantgarde buyer. Regarding the next purchase of a TV I will be happy with that what was expensive three years ago.
The 1.900€ investet in the Samsung TV 4 years ago means the value is gone. The money invested in my Oracle Delphi turntable or the Mcintosh tube gear means an invest which is value keeping.
