Query: Blu-ray at its best?

I thought that the Franco Zeffirelli film starring Placido Domingo and Teresa Stratas on my copy of DVD was great. But, except for a bit of audio glitch, this is a good example of Blu-ray at its best. Video is so sharp and detailed on my 92" CRT projected screen that all emotions on the performers' faces hit me like never before. For the first time, I keenly felt the anguish portrayed and couldn't hold back my tears.A must own for all opera lovers!
