Is my plasma too old?

[mrchallenge]

Hi, I have a Pioneer Elite Pro-940HD 42' Plasma.

I bought it for $3300 back in early 2007. At the time, it was pretty top of the line stuff and got good reviews when it came out.

I use it primarily to watch blu rays since I don't watch alot of TV. Films look very cinematic on it.

I can't help but wonder though, the contrast ratio of my plasma is around 600:1 to 800:1. That was considered pretty high back in 2007, but is now considered pitiful compared to newer models. Even your average entry level LCD from best buy has a better contrast ratio than that.

Am I reading too much into it or is my TV a little too old and now being outperformed by newer model LEDs? Am I missing out on details that I would've gotten on a tv with a higher contrast ratio?
