Query: Great Songs undone by poor audio quality

Let me say, that I'm not a big fan of EC, but I really love his work with Cream. So when I brought the boxed set home, I immediately put in CD two and prepared myself to be blown away. I was, but not by the music, but by the horrendous sound quality of the CDs...The quality was so bad that I returned the boxed set for a refund.
