Well, I suppose you can't duplicte the "electricity" of being at the Met but other than that, Live in HD is the best. I mean many in the audience even applauded the performers at the end of each act and they justly deserved the applause for their acting as well as their singing. Caution: the opera is loooonnnggg -- almost 6 hrs -- and even with intermissions its a marathon. You need to love the the music and Wagner isn't for everyone, but the themes -- power vs love -- are universal and at the end, there were several around me who were emotionally moved as I was.
