IIRC, phillips is one of the more reputable brands when it comes to CRTs, and this one uses NF diamondtron - the best tube in the market at the moment. I would be hesitant to call it the best, there is NEC/Mitsubishi which is regarded the best in consumer grade market. then again there are some high class brands like Eizo, Iyama, Totoku an whatnot...
