It can be a factor in Brand value and Brand quality, but as i mentioned earlier, Sony is in a different TV market with flat panel TV´s then they were with CRT. They have a strong Yen and fierce competition so why shouldn´t they suffer from all those factors? I was suggesting that the Brand value might have been and still is a factor that reduce the damage from all those factors.
For your father it´s sony, for me it´s denon with no emperical evidence except money wasted
BLASPHEMER!
Seriously, though, I have had the exact opposite experience. The 3 Denon receivers (and 1 car head unit) I have owned are among the best purchasing choices I have ever made. And all of them have worked and still work with zero problems despite, in some cases, years of heavy use.
