I haven't posted here for sometime but wanted to provide some quick feedback after having my 55" VT30 calibrated and home theater audio calibrated this past Monday by one of the best in the industry.
In a word, WOW!

I simply cannot believe the level of improvement. Not sure since others have mentioned it definitely making a big difference but I simply was not prepared for the level of difference it truly made. I bought my display last October and waited until now for W. Jeff Meier to calibrate it when doing his calibration tour in Oregon. He's one of the best and I would be happy to share more feedback if someone wants to ask more via a PM. I do want to provide input to everyone wondering if it is worth the cost that I was using the recommended D-nice settings that improved my picture past the provided THX setting so it wasn't like I felt my PQ was horrible. Still I never felt like the PQ had the wow factor it should being the top of the line plasma display from Panasonic so widely reviewed in a positive light for the most part. Yes, the display like any has flaws but the pop to the PQ is now where it should be.
Here is Jeff's information for those interested:

He is truly that good. All the doubt wondering if it was going to be worth the cost simply vanished quickly once I was able to experience the PQ more since Monday. It was so much worth the wait. I truly can't wait to watch the best of my blu-rays again just to experience the improvement. The picture has a level of depth and 3 dimensional quality to it that can't believe let alone the accuracy with the colors, contrast, gamma, etc. And the extra hundred to do the audio was easily also worth it. I only had the video scheduled but since he had time after asking him questions on what he could improve, I couldn't help but have him tweak the audio as well.

After all the work is done, he provides a professional report detailing before and after data.
Long story short, I recommend to anyone that hasn't had their display calibrated to do it even if satisfied but feeling like it doesn't have the pop or wow factor it should. That is if the calibrator is up to a high standard to truly make a difference. I have read some say that the calibration may add the extra 15% or so improvement over the D-nice settings. All I can say is even though it is subjective and hard to put a percentage improvement on things in life knowing each person views things differently, my impression is that the percentage improvement is much greater than I was led to believe when asking those having a calibration performed what they thought. I am not exaggerating to get replies or responses but more letting everyone know that I truly feel I have a totally new display installed in my home theater room. Of a side note if anyone is interested, Jeff was the one that was supposed to help calibrate the displays that Value Electronics used last year as a shootout but he was not available at the time. I can provide more through a PM if interested. He's done some very highend calibrations including those in the business.
Oh, I know Htwaits will likely reply telling me to post my calibration results in the cal thread

. By the way, thanks Htwaits since you recommended I wait for Jeff Meier months ago when I asked you via a PM. You were right, he's that good and one of the very best! Anyhow I intend to add a review in the calibration thread soon when time permits, just wanted to let VT30 owners here know my experience. I just received an early Christmas present.

Happy viewing!
