Query: Worst sound quality in a CD...

I love Beethoven's Symph #5 (who doesn't?) but the sound quality is terrible---granted the recording here is from the 1940's, and I wasn't expecting great sound quality. However, the sound quality on this CD was so bad that I doubt I'll bother to listen to it again---I couldn't hear much and my only regret is I can't return it.
