Query: Never worked correctly

All of the features seem to work as advertised, except the unit powers itself off after about 15 minutes. That's highly annoying and renders it useless. I saw another review here on Amazon that recommended a reset procedure, but multiple attempts yielded no results. The unit still powers itself off after 15 minutes. For the 15 minutes that the unit will stay powered on, it works as advertised. Sound quality is about what you'd expect from such small speakers and low-wattage power amp. It sounds totally acceptable. Not mind-blowing hi fidelity sound, but totally passable. I'm giving a try to the Teac all-in-one to see if it works any better. If not, I'll break down and piece together a component system. I just like the idea of how easy to use an all-in-one is, but quality of the components seems to be a pretty consistent issue with all of these brands.
