Long time listener-a few comments

I have enjoyed almost every episode of this well scripted and researched show. What has been bothering me are the esthetics of the show. There are about 4 sound effects/transition sounds that are used in every show. I would really like to see these improved sound quality wise AND more variety to the sounds. Personally I especially dislike the tinny old time piano effect used. As a classical musician I am especially sensitive to sound but I am close to be not being able to listen anymore...but I am drawn back by the presentation of the stories. Any hope for sound variety?
