I use few......that I am very familiare with and few of my own that are mixed bag of reference recordings with helpful material for evaluating dynamics, stage, seperation, low level detail, harmony, balance, realism etc.
You can try Usher demo CDs I,II,
Chesky rec. demo.
Stereophile demo discs.
But for the ladies.....I think that number of tracks on both Usher CDs are great weapon. I ask my wife to listen to few tracks from those CDs and she loved it.( through my new CD player which she saw for the first time. When I told her that I was thinking about buying it, she said......YAPPPP
I THINK IT IS WORTH IT, without asking how much was it and after 30min of listening in silence. Well, she did not know that I already bought it,.......shhhhh.)
