Query: Very good opera poor CD quality

I bought the CD as a present for my father.When I got it I was very unplesantly surprised that the sound of the recording is dull( it was made originally in 1961) and it was not digitally retouched although according to the descrition the CD was made in 2000.I contacted the seller regarding the problem no response at all.I dont recommned that CD if you are looking for good sound quality.Ovearall the opera is a masterpiece.
