Greetings
And you have it ... there is no right answer.
I played with the 11" Sony OLED and as beautiful as the image is on that ... better than any plasma out there right now ... it was a toy and I would not do any serious viewing on it.
There is something to be said about big picture, big sound ... as opposed to big sound small picture. I think we tend to tolerate big picture crappy sound more.
Audio Ark is not interested in my services. Tried ... as they say they do it in house ... and they don't. But they still tell you it's done ...
National AV ... their stuff is calibrated usually. You can tell which of the flat panels are worked on by looking for the THX sticker on the bezel somewhere. Doesn't stop someone from resetting the TV though.
Sense Audio (formerly premier audio) ... the projectors are calibrated.
