The instrument has to sound for a good sound and enough "oomph" comfortable for our entire attic. Operation is simple, the remote tiny, but works well, the display is easy to read. Both CD (also MP3) and USB flash drive works fine, radio and cassette I do not use. An asterisk deduction because the display does not have ID3 tags, or at least filename of MP3s shows - at least I have not figured out how to do that and in the manual is also nothing about it. I think it is impossible. Still, a good solid machine!
