Recommended CD's for classical good recording ?

HI,

I have been checking around and purchasing CD's (I am getting more and more into classical music) but several of the recommended classic recordings were done back in the 40's and 50's, and don't sound all that dynamic in my system. They are somewhat flat and 1-dimensional. Perhaps they are better on vinyl? Most of the best recordings I have were recorded either recently or back in the 70's.

What are some good recordings to seek out? There is a good classical music store nearby
