Very new to forum. Would greatly appreciate your knowledgeable input. Intend to have garden party, with limited space and without access to mains electricity. Have done some research and am considering the purchase of Astell&Kern AK Jr & Ultimate Ears UE BOOM 2. Like the idea of having high res sound, and weather proof speaker that could be hung from a garden parasol. Would be great to know what components you'd buy, and whether securing high res music is going to be an issue.
