I bought a Athearn genesis CSX MP15ac w/sound on Ebay used for $110.00,This engine runs quite well.It has the QSI sound decoder in it.It is very detailed! 
I do believe Atlas uses the same QSI decoder(dual mode).The sounds are realistic to me.Of course the sounds are adjustable(volume,different horns,manual throttle nothing,etc) via DCC controller.Personally i would trust the Atlas version over the Athearn(IMHO).BTW here is a video i made for Youtube of the QSI sound <!-- m --><a class="postlink" href="http://www.youtube.com/watch?v=RuPNLMVKHnw">http://www.youtube.com/watch?v=RuPNLMVKHnw</a><!-- m --> It is the same as the Atlas MP15ac.
