I can only say that I have been listening almost every day to this recording and don't find the orchestra or any vocal performances a bar to great enjoyment. I think a fuller orchestra would have been any nicer and richer, but I've really enjoyed this. The BBC broadcast of extracts has a fuller orchestra, but I only intermittently listened to it in the years when it was all I had. Listening to the full opera without breaks is really satisfying. I'm not meaning to deny what people above said they felt, but to point out that for some of us this is a very enjoyable release that bears repeated listening.
