Query: Very poor sound quality

I saw this opera performed at Glimmerglass and found it simply wonderful. Wanting to hear the opera again, and thinking that a recording with Placido Domingo should be pretty good (at least!), I was very disappointed to discover how poor this recording is.I am not talking about the actual performance, but the mastering of the sound quality on the CD. The recording is so soft that even with my stereo turned up to full volume (and I have tried it on four different stereos) the record is muted, hard to hear, and very frustrating to listen too.There are plenty of recordings of this opera out there, including other recordings with Placido--spend your money elsewhere.
