I have a few questions: Do you see every pixel discretely? Does a vertical or horizontal single-pixel wide line render crisply? There are things beyond highly accurate color representation that make a monitor great.
You can literally see things in your images on an LCD that you could never have hoped to have seen on any CRT.
If I were you, facing a decision to spend thousands more on a new CRT or LCD, I'd see if I could put them side by side and compare directly. Have you ever put a good LCD on your system and compared it side by side with your Artisan? Perhaps an Eizo LCD, for example.
IMO, CRT technology - even tweaked to the max and with gee whiz self-calibrating functionality - is last century's tech.
