The great aspect of classical music is that you have a choice of many, many recordings.
If you have a favorite chamber work, I suggest that you go out and find different renditions, I enjoy reading the reviews and finding about all the recordings on classicstoday.com.
When you get the hang of classical music, you might end up with collecting different interpretations of your favorite works.
It's okay to have a couple sets of the complete symphonies of Beethoven!
