Query: Poor sound quality

Barber's Adagio is one of the most beautiful pieces of classical music in existence. This album doesn't give it fair treatment. The sound quality is terrible; it's thin and lacks depth, and the average volume of the first track is so low that you have to crank your stereo to the point of hearing hissing white noise.I recommend passing this one by, and buying a different version.
