Query: Get the BMG edition instead

Although the performance is, I feel, one of the best available of this opera (see my review for the BMG edition), this Opera D'Oro release is from a noisy and distorted mono sound source whereas the BMG release is from the original clean stereo Austrian radio tapes. The only thing you get here that BMG failed to provide is a German-English libretto, which one should be able to download.
