What would u like on sacd?

What would my Audiogoner friends like to see and hear issued on sacd? I myself would love to hear the great operas containing the great tenors that I love, such as Corelli, Bergonzi, Vickers, Stefano, and yes Delmonaco.I know that opera ussually get's pushed aside for other music that is more popular with a greater number of people. So any of you have your picks not yet issued on sacd?
