Review by Anonymous: Sony 50XS955 Plasma Display Posted on June 8, 2005 by Gregg Loewen I just had Gregg Loewen from Lion AV calibrate my Sony 50XS955 almost 2 weeks ago. He is a great ISF tech and did a wonderful, thorough job calibrating my display. (I don’t hand out compliments lightly) (6/8/2005)
