I'm looking for something equivalent to Andrea Bocelli's Sentimento. It's a collection of songs, not an entire opera. SACD or very good quality CD preferred.
This isn't what you want, but I'm recommending it anyway.
Puccini's Turandot, with Joan Sutherland in the title role, and with (a young) Luciano Pavarotti, conducted by Zubin Mehta (Polygram #414274). Recorded in the '70s and still the finest performance and recording of this opera I've heard. Sutherland is amazing.
