Top 10 Must-have Classical CD's

I just upgraded all of my components and am now into tube amps. Everything sounds so good and I am, therefore, buying lots of new music.

What few classical CD's that I have picked up through the years have started a desire to flesh out my library.

I would be interested in, please, a list of "top ten" recomendations for the clasical newby including the piece, artist, label etc.

Thanks!
