Hey all! I'm looking for an Xmas present for my mom -- an iPad accessible amp to take to the fitness classes she teaches so that she can use the music on her iPad and have a better speaker than the one at her facility. I've looked at a few, but I was wondering about any you all might recommend. I'm looking for a fairly nice one, preferably bluetooth (if they all aren't already) so that she can add additional speakers and headsets down the line. Thank you so much!
