Query: Casta Diva in a Tin Can

This was the first "Norma" I ever purchased, and it turned me off to live opera recordings for a LONG time (I am still wary of them and investigate them carefully).While I recognize that Norma was a great Callas role (I am not a Callas fan), unfortunately, this 1952 does not show it. In fact, the entire recording sounds like it was recorded in a tin can, and there is an annoying (though periodic) hiss. The volume balance is also a problem--some tracks are inaudible while others will blast you into the next room.The moral of the story is, pick another "Norma" to purchase (preferably the Sutherland/Horne one).
