Is this system more about pleasing you or your daughter? Get her what she wants because she will probably end up not using what you think she may like and it will sit there collecting dust or break it. Don't overthink it.
Speakers for daughter
I was going to buy powered small speakers for my daughter's first sound system to go with A Project Debut Carbon Evolution but now she seems ok to accept an integrated amplifier from me to power speakers. Thinking about the Elac UNI-FI UB 51 or ELAC Uni-FI Slim B5 U5 after researching similar priced speakers such as the Elac Debut 2.0 B5.2, Paradigm Monitor SE Atom, Wharfedale Diamond 12.1, and Kef 150. I have not listened to any speakers yet at the price point. Any comments?
